DETAILED DESCRIPTION

(17) Referring now to the drawings and specifically to FIGS. 1 to 6 and 10A-10D, there are shown guide devices 100, 200, and 300, all of which are suitable for use with a drill bit.

(18) Each of guide devices 100, 200, and 300 comprise a hollow body 2 having a first end 4, a second end 6 and a continuous section 8 intermediate the first end 4 and the second end 6. An opening 2a extends from the first end 4 through the continuous section 8 to the second end 6. The hollow body 2 is generally defined by an inner wall 2b bounding the opening 2a, and an outer wall 2c. In each of guide devices 100, 200, the cross sectional internal diameter d of opening 2a bound by inner wall 2b is constant from the first end 4 of hollow body 2 to the second end 6 of hollow body 2. In the guide device 300, the cross sectional internal diameter may vary along the length of the device, as shown in FIG. 10C. In some embodiments, guide device 100 comprises a cross sectional internal diameter d of approximately 0.3 (0.76 cm). In some embodiments, guide device 200 comprises a cross sectional internal diameter d of approximately 0.28 (0.71 cm). In some embodiments, a guide device 100, 200 comprises a cross sectional internal diameter d between approximately 0.28 (0.71 cm) and 0.3 (0.76 cm). In various embodiments, the cross sectional internal diameter d can be any other size depending on the diameter of drill bits to be used with the guide devices 100, 200. For example, where a hole is to be drilled with a 9/32 (0.28125) drill bit, a suitable internal diameter d may be between 0.282 and 0.3. Preferably, the internal diameter d is slightly larger than the diameter of the drill but, but small enough to prevent significant movement of the drill bit laterally (e.g., by translation) and/or radially (e.g., by tilting) away from the central axis of the hollow body 2.

(19) Referring specifically to guide device 100, FIGS. 1 to 3, the cross sectional external diameter D of opening 2a bound by outer wall 2c is variable from the first end 4 of hollow body 2 to the second end 6 of hollow body 2. Conveniently, this provides thinner and thicker portions along the external walls 2c of hollow body 2 to enable a user to easily grip and manipulate guide device 100 into a desired position. In some embodiments, guide device 100 comprises a cross sectional external diameter D that ranges between approximately 0.4 (1.02 cm) and 0.6 (1.52 cm). In certain embodiments, the cross sectional external diameter D may include portions larger and/or smaller than the range of between 0.4 and 0.6, for example, based on considerations such as a size of a drill bit to be used with the guide device 100, ergonomic considerations, or the like.

(20) Guide device 100 is provided with a first end 4 and second end 6 having a greater cross-sectional external diameter D than that of continuous section 8. In some embodiments, the cross sectional external diameter D for guide device 100 is approximately 0.5 (1.27 cm) for a length of approximately 0.5 (1.27 cm) at first end 4 of hollow body 2, approximately 0.4 (1.02 cm) for a length of approximately 0.35 (0.89 cm) at continuous section 8 of hollow body 2, and approximately 0.6 (1.52 cm) for a length of approximately 0.4 (1.02 cm) at second end 6 of hollow body 2. The cross-sectional external diameter D may be determined based on the desired cross-sectional internal diameter d such that a structurally robust wall thickness is maintained. Moreover, the relative lengths of the first end 4, second end 6, and continuous section 8 may be varied, for example, to provide a structurally robust guide device 100, to accommodate a desired configuration of apertures, etc.

(21) In use, a drill bit 32 (FIG. 8) is positioned within the opening 2a of the hollow body 2 such that the drill bit extends through the opening 2a from the first end 4 to the second end 6 and is coaxially or substantially coaxially located with the hollow body 2 of the guide device 100 and 200, and orthogonally located relative to a material or substrate being drilled. Guide device 100 and 200 can thereby allow a drill bit to freely rotate about the fixed rotational axis of the drill to create a hole, whilst preventing free lateral or tilting movement around the hole being drilled. In this way, the guide device 100 and 200 allows a user to control the position and size of the hole being created by the drill.

(22) Drill bits may be designed such that each drill bit comprises a sharpened or tapered end that cuts a hole in a material and a spiral screw thread or auger that lifts the material up out of the hole and out of the material. In the embodiment shown in FIGS. 1 to 3, guide device 100 is further provided with a plurality of apertures 12, 14 and 16 located spaced apart on the hollow body 2 of guide device 100. Apertures 12, 14 and 16 extend through the hollow body 2 from the inner wall 2b to the outer wall 2c such that the space within opening 2a is in communication with the exterior space surrounding the guide device 100. Apertures 12, 14 and 16 may be perpendicular to the central axis of the opening 2a or may extend at an angle smaller than 90 degrees relative to the central axis of the opening 2a. Apertures 12, 14 and 16 may be sized and shaped to facilitate ejection of dust and waste material from guide device 100. Thus, dust and waste material being carried away from the material being drilled by the auger may pass radially out of the hollow body by passing from the space within opening 2a, through the inner wall 2b and outer wall 2c at an aperture 12, 14, 16, to the exterior space surrounding the guide device 100. In some embodiments, the apertures 12, 14, and 16 may advantageously prevent clogging that may occur if all dust and waste material were carried through the length of the guide device 100 by the auger portion of the drill bit.

(23) In some embodiments, each of apertures 12 and 14 are approximately 0.08 (0.2 cm) in width. In various embodiments, the apertures 12 and 14 may have a width between approximately 0.05 and 1.2. Each of apertures 12 and 14 may be regularly spaced apart on the circumferential body of guide device 100 at the second end 6 of hollow body 2 and continuous section 8 of hollow body 2 respectively. Apertures 12 situated proximal to second end 6 of hollow body 2 may be more numerous than either of apertures 14 or 16 to facilitate ejection of dust closer to the sharpened or tapered end of the drill bit. This may prevent dust build-up inside the guide device 100, which may cause the drill bit to slow down or become blocked whilst in use.

(24) Apertures 12, 14 and 16 may further act as a heat sink to dissipate any heat generated by the drill bit whilst rotating within the guide device 100. For example, heat may be generated due to friction such as between the drill bit and the material being drilled, and/or between the drill bit and the interior wall 2b of the hollow body 2. Accordingly, heated particles and/or air contained within the opening 2a may be allowed to move outward and away from the drill bit through apertures 12, 14, 16.

(25) Guide device 100 may further comprise a locating section 20. Locating section 20 is provided to assist a user to position the guide device 100 correctly and easily on a material being drilled. In some embodiments, locating section 20 comprises a hollow cylindrical section integrally formed at the second end 6 of guide device 100 remote continuous section 8. The internal diameter of locating section 20 corresponds to diameter d bound by inner wall 2b of hollow body. In some embodiments and as shown in FIGS. 1 to 3, the width or external diameter D of locating section 20 is reduced relative to largest extent or fullest external diameter D at the second end 6 of hollow body 2 such that locating section 20 is in effect indented relative to said fullest external diameter D. In some embodiments, external diameter D of locating section 20 is approximately 0.4 (1.02 cm), whilst external diameter D of second end 6 of hollow body 2 is approximately 0.6 (1.52 cm).

(26) The location section 20 may be particularly useful, if a user desires to create a hole in a first material through a fixing aperture in a second material in order to secure the second material to the first material. A user is able to easily seat guide device 100 in the fixing aperture of the second material using locating section 20 to facilitate drilling a hole in the first material. It is preferable for locating section 20 to seat tightly within the fixing aperture, to ensure a drill bit will be centered within the guide device. Consequently, a hole when created, will be centered within the fixing aperture of the second material.

(27) Accordingly, in some embodiments, guide device 100 is suitable for use in a circular shaped fixing aperture which has a diameter of approximately 0.4 (1.02 cm) or greater.

(28) Although, locating section 20 comprises a hollow cylindrical section with a cross sectional external diameter of approximately 0.4 (1.02 cm), it is easily understood that the shape and size including the cross sectional external diameter of locating section 20 can be adapted as desired by a person skilled in the art to enable the guide device seat within any shape or size fixing aperture.

(29) In one example, the guide device could be used in conjunction with a fastening system comprising rails or track which are used to mount cladding materials to a substrate. Usually, with such fastening systems, the rail or tracks are provided with elongate fixing apertures to facilitate movement of the cladding materials due to environmental conditions when mounted to the substrate. Locating section 20 of guide device 100 can be configured to seat within the elongate fixing apertures such that the guide device 100 is centered within the elongate fixing aperture of the fastening system. The use of guide devices with materials having fixing apertures is described in greater detail with reference to FIGS. 7 and 8.

(30) Referring now to FIGS. 4 to 6, guide device 200 includes a locating section 20 configured to seat within an elongate aperture 52 of the kind shown in profile 50 of FIG. 7. Guide device 200 comprises a hollow body 2 having a first end 4, a second end 6 and a continuous section 8 intermediate the first end 4 and the second end 6. Opening 2a extends from the first end 4 through the continuous section 8 to the second end 6. The hollow body 2 is generally defined by an inner wall 2b bounding the opening 2a, and an outer wall 2c. Guide device 200 extends approximately 1.5 (3.81 cm) from first side 4a of first end 4 to second side 6a of second end 6. In some embodiments, the guide device 200 may be longer or shorter than 1.5, for example between 0.5 and 3, between 1 and 2, etc., based on a length of a drill bit to be used with the guide device, a desired depth of a hole to be drilled in a substrate, a thickness of a substrate to be drilled, etc.

(31) In this embodiment, guide device 200, comprises a substantially cylindrical shape at first end 4 and a substantially hexagonal shape at second end 6. The external cross-sectional diameter D of continuous section 8 proximal second end 6 increases in thickness until the shape of the hollow body changes from a circular shape to hexagonal shape. In some embodiments, the hexagonal shape extends approximately 0.62 (1.58 cm) from line 8a (shown in FIG. 4) to second side 6a. Similar to the guide device 100 depicted in FIGS. 1-3, cross sectional internal diameter d of opening 2a bound by inner wall 2b is constant from the first end 4 of hollow body 2 to the second end 6 of hollow body 2. In some embodiments, cross sectional internal diameter d is approximately 0.28 (0.71 cm), for example, based on an external diameter of a drill bit to be used with the guide device 200 and/or a diameter of a hole to be drilled in a substrate.

(32) Locating section 20 of guide device 200 comprises an indent 22 on opposing sides 22a of the hexagonal shaped second end 6. In some embodiments, each indent 22 recesses opposing sides 22a of the hexagonal shaped second end 6 by approximately 0.068 (0.17 cm) such that the hexagonal shape of the indented locating section 20 is smaller with two longer sides than the hexagonal shape of second end 6.

(33) Guide device 200 is further provided with a plurality of apertures 24 located spaced apart on hexagonal shaped second end 6, wherein apertures 24 are sized and shaped to facilitate ejection of dust and waste material from the guide device 200. Similar to the apertures 12, 14, 16 described with reference to FIGS. 1-3, the apertures 24 in guide device 200 permit the passage of dust and waste material such that at least a portion of the dust and waste material can leave the guide device 200 without having to be carried as far as the first end 4 within the opening 2a by the auger portion of the drill bit. In some embodiments an aperture 24 is located on each face 24a or some of the faces 24a of the hexagonal shaped second end 6. In some embodiments, each of apertures 24 is configured to occupy up to approximately 70% of the width of each face 24a of the hexagonal shaped second end. In further embodiments each of apertures 24 are approximately 0.18 (0.48 cm) in diameter. This ensures that dust build-up inside the guide device 100, which may cause the drill bit to slow down or become blocked whilst in use, is prevented or reduced.

(34) In some aspects, the size of apertures 24 can be determined so as to facilitate the passage of dust or other debris out of the opening 2a. Because debris within the opening is being carried by an auger portion of a rotating drill bit, the debris may generally be moving along a spiral or helical path along the inner edge 2b bounding the opening 2a. When debris leaves the opening at an aperture 24, it can travel in a direction tangent to the circular profile of inner edge 2b, rather than radially outward. Accordingly, increasing the size of the apertures 24 may allow a greater portion of the debris to be propelled outward through the apertures 24.

(35) Each of guide devices 100, 200, 300 are preferably formed from a suitable metal such as steel, in which the various features of each respective guide device 100, 200 are easily machined. In some aspects, guide devices 100, 200, 300 may be formed from other suitable hard metals, such as titanium. Preferably, the material of the guide devices 100, 200, 300 is resistant to degradation due to heat build-up from mild contact pressure during use. Moreover, the material is preferably ductile and rigid so as to resist input forces over a lifecycle including hundreds or thousands of uses.

(36) In various embodiments, the guide devices described herein may be designed to be compatible for use with a particular profile or other structure to be mounted to a substrate, or to be compatible with an industry standard fixing aperture or other structure. For example, guide devices 200 and 300 are designed for use with a profile 50 comprising elongate hexagonal shaped fixing apertures 52 such as that shown in FIG. 7. Profile 50 is one example of a profile that forms part of a fastening system used to mount cladding materials to a substrate, in particular fiber cement cladding materials mounted to a structural substrate. Profile 50 is provided with hexagonal shaped elongate fixing apertures 52. Locating section 20 of guide device 200, 300 is configured to seat within the elongate fixing apertures 52 such that guide device 200, 300 is centered within the hexagonal shaped elongate fixing aperture 52 of profile 50.

(37) Profile 50 may be one of a plurality of panel support profiles used to form a fastening system, whereby a first panel support profile 50 is inverted relative to the second panel support profile 50 such that the first and second panel support profile members seat together. The shape of the first panel support profile allows two first panel support profiles to interlock such that one of the two panel support profiles can be fixed to a building substrate and support and retain a cladding panel fixed to the other panel support profile. For example, one of the tracks can be affixed to the back side of a heavy paneled building product, such as a 4 ft.8 ft. (121.9 cm243.8 cm) cladding panel. The other one of the tracks can be affixed to a building frame. The fastening system can comprise more than one pair of the elongated tracks arranged in a spaced apart relationship between the cladding panel and the building frame. The tracks facilitate alignment of the cladding panel to the building frame and allow a large, heavy cladding panel to be easily and quickly attached to the building frame. The tracks are also designed to be self-locking in that the weight of the cladding panel automatically locks the track on the back side to the track on the building frame. Furthermore, the tracks are designed to be positioned in a manner such that they are concealed from view and do not detract from the aesthetics of the cladding panel.

(38) In some embodiments, the profile 50 can be formed from extruded aluminum alloy or folded steel. It is to be understood, that any other suitable material or forming technique known to a person skilled in the art can also be used, for example, the material chosen to form a support profile 50 suitable for attaching a cladding panel to a structural substrate could also be formed from one or more of machined wood, fiberglass, plastic, hardened rubber, metal alloys, carbon fiber, or other similarly hardened woven composites. It is also understood that the forming technique used to form the profile 50 is selected in accordance with the material chosen to form the profile 50. Such suitable forming techniques include, for example, extrusion, mold casting, sheet folding or machining.

(39) In the panel support profile 50 of FIG. 7, fixing apertures 52 are configured to seat a nut or fasteners comprising a polygon shape. In some instances, fixing aperture 52 comprises an elongate polygonic shape, wherein at least one pair of opposing sides of the polygonic shape are longer than the other sides of the polygonic shape to allow lateral movement of a fastener within the fixing aperture 52. In most instances, nuts or fasteners comprise a hexagonal shape, thus in this instance, the fixing aperture 52 comprises a hexagonal open ended channel or an elongate hexagonal open ended channel, however it is to be understood that any polygonic shaped aperture or elongate polygonic shaped aperture suitable to seat a nut or fastener can also be used. One of the advantages of using this shaped fixing aperture is that an end user is able to drill holes for the fasteners or fixing elements easily without needing to lift or move the first panel support profile member.

(40) Referring now to FIG. 8, there is shown an example of guide device 200 together with a drill 30 in use. The guide device 200 and drill 30 are being used to create a hole in a substrate 40 through a hexagonal shaped elongate fixing aperture 52 of a profile 50, such as the profile 50 depicted in FIG. 7, such that a fastener may be accommodated within the hole to secure the profile 50 to the substrate 40. Substrate 40 may be a building substrate, such as a building framework, or may be an article to be mounted to a building substrate, such as an exterior cladding panel. Drill 30 is provided with a drill bit collar 34.

(41) In use, drill bit 32 is positioned within the opening 2a (FIGS. 4-6) of the hollow body 2 such that the drill bit 32 extends through the hollow body 2 from the first end 4 to the second end 6, and is coaxially located with the hollow body 2 of the guide device 200 and orthogonally located relative to a material being drilled (e.g., the substrate 40). Guide device 200 allows drill bit 32 to freely rotate about the fixed rotational axis of the drill to create a hole, whilst preventing free lateral movement around the hole being drilled. In the perspective view of FIG. 8, the locating section 20 (FIGS. 4-6) is seated within and surrounded by the fixing aperture 52. The material of the support profile 50 surrounding the fixing aperture 52 maintains the guide device 200 in a fixed location while a hole is drilled in the substrate 40. In some aspects, an end of the locating section 20 (FIGS. 4-6) of the guide device 200 rests against the substrate 40 and/or the second end 6 (e.g., the indent 22 as shown in FIGS. 4-6) of the guide device rests against the surface of the support profile 50.

(42) Initially, drill bit collar 34 sits above guide device 200, as the tip of the drill bit 32 rests on the surface of the substrate 40 and the length of the drill bit 32 beyond the drill bit collar 34 is greater than the length of the hollow body 2. As the hole is being drilled, the auger (not shown) of drill bit 32 lifts the detritus 26 up out of the hole being created towards apertures 24, where it is ejected from guide device 200. As the hole is drilled and the tip of the drill bit 32 extends into the substrate 40, drill bit collar 34 moves into contact with the first end 4 of guide device 200 when the drill bit 32 has created a hole of desired depth in substrate 40. When the drill bit collar 34 comes into contact with the first end 4 of the guide device 200, the drill bit 32 is prevented from penetrating deeper into the substrate 40. The contact between the drill bit collar 34 and the guide device 200 can indicate to a user drilling the hole that the hole is completed, and may prompt the user to remove the drill 30, drill bit 32, and/or the guide device 200 from the hole and continue to drill a second hole at another fixing aperture of the support profile 50. In some aspects, the contact between the drill bit collar 34 and the guide device 200 may further be advantageous by preventing a user from inadvertently drilling a hole deeper than desired, which may penetrate, puncture, mar, or otherwise disturb the other side of the substrate 40 (e.g., the visible exterior surface of a wall cladding panel or the like).

(43) After a hole is drilled to the desired depth within the fixing aperture 52, a mechanical fastener can be inserted through the fixing aperture 52 of the support profile 50 and into the hole in the substrate 40 to fix the support profile 50 to the substrate 40. For example, suitable mechanical fasteners for fixing the support profile 50 to the substrate 40 through fixing aperture 52 may include short or long fiber cement screws, angled pro-twist screws, and/or undercut anchors with or without undercut holes.

(44) Referring now to FIGS. 9A-9C, there is shown an example of a fastening system 60 which may be assembled using the guide devices 100, 200 disclosed herein. The fastening system 60 comprises two first panel support profile members, such as profiles 50 depicted in FIGS. 7 and 8. In the embodiment shown, two profiles 50 are seated together to form each row of the fastening system 60. For clarity, profiles 50 hereinafter are referred to as the first and second panel support profile member 50a and 50b. It is to be understood that references to the first panel support profile member 50a should where appropriate extend to the second panel support profile member 50b.

(45) Referring specifically to FIGS. 9A and 9C, there is shown a cladding panel 62 attached to a structural substrate 54 using fastening system 60. Cladding panel 62 can comprise a building material comprising cementitious materials, gypsum, or other suitable inorganic building materials such as those containing cellulose, glass, steel or polymeric fibers. In the embodiment shown, cladding panel 62 comprises a fiber cement cladding panel comprising a front face 62a and a rear face 62b and an edge member 62c intermediate to and contiguous to the front face 62a and the rear face 62b. Structural substrate 54 typically comprises a building framework comprising timber or metal framing materials.

(46) In the embodiment shown, a plurality of fastening systems 60 are used to attach cladding panel 62 to structural substrate 54. It is to be understood that the number of fastening systems and/or fastening configurations used to attach the cladding panel 62 to structural substrate 54 is variable and is dependent on both the size and shape of the cladding panel 62 and the desired wind load levels that the end user wishes to achieve.

(47) For example, in the embodiment shown, a 4 ft.8 ft. (121.9 cm243.8 cm) cladding panel 62 having a thickness of 7/16 (1.1 cm) required 8 fastening systems to attach the cladding panel to the structural substrate and to achieve a minimum design loading of 54.6 psf. In this example, each fastening system was attached to the panel and the structural substrate using fasteners wherein the fasteners were spaced apart from each other by 12 (30.5 cm). The first fastener used to attach the first panel support profile member 50a to the rear face of the cladding panel 62b was placed at 6 (15.2 cm) from edge member 62c. The fasteners used were undercut anchors.

(48) Referring specifically to FIG. 9C, there is shown an enlarged side view of one fastening system 60 of FIG. 9B, wherein a cladding panel 62 is attached to structural substrate 54 using fastening systems 60.

(49) First panel support profile member 50a comprising a first arm 53, a second arm 55 and a bridging portion 57 intermediate the first and second arm 53, 55 is attached to the rear face 62b of the cladding panel 62 using fasteners via fixing apertures 52. Similarly second panel support profile member 50b, also comprising a first arm 53, a second arm 55 and a bridging portion 57 intermediate the first and second arm 53, 55 is attached to the structural substrate 54 using fasteners via fixing apertures 52. The fasteners may be inserted through fixing apertures 52 into pre-drilled holes in the cladding panel 62 and the structural substrate 54. Pre-drilling may be accomplished using any of the guide devices 100, 200 depicted and described with reference to FIGS. 1-6 and 8.

(50) First panel support profile member 50a is inverted relative to the second panel support profile member 50b such that the first and second panel support profile members 50a and 50b seat together. Second arm 55 seats within the u shaped receiving channel defined by bridging portion 57, first arm 53 and projecting member 53a such that first arm 53 of the first panel support profile member 50a is seated adjacent to the second arm 55 of the second panel support profile member 50b and vice versa. Projecting member 53a of the first arm 53 is retained by the recess defined by side section 57 and second arm 55. The weight of cladding panel 62 forces first and second panel support profile members 50a and 50b into position thereby attaching cladding panel 62 to structural substrate 54.

(51) In practice, an end user firstly attaches the first and second panel support profile members 50a and 50b to each of the cladding panel 62 and the structural substrate 54 separately using the methods described above with reference to FIGS. 1-8, and then the first panel support profile member 50a and second panel support profile members 50b are secured together. The end user can use any suitable means to secure the first and second panel support profile members 50a, 50b together, as the shape of the first and second panel support profile members 50a, 50b allows the first and second panel support profile members 50a, 50b to interlock.

(52) For example, the end user could hang the first and second panel support profile members 50a, 50b together whereby first panel support profile member 50a is moved into a position where it is raised out of alignment with second panel support profile member 50b such that second arm 55 of first panel support profile member 50a are positioned above the u-shaped receiving channel defined by bridging portion 57, first arm 53 and projecting member 53a of the second panel support profile members 50b. Projecting member 53a of first panel support profile member 50a is also positioned above the recess defined by side section 57 and second arm 55 of the second panel support profile members 50b. The first panel support profile member 50a is then moved into alignment with second panel support profile member 50b such that second arm 5 of first panel support profile member 50a is seated within the u-shaped receiving channel defined by bridging portion 57, first arm 53 and projecting member 53a of the second panel support profile members 50b; and projecting member 53a of first panel support profile member 50a is seated within the recess defined by side section 57b and second arm 55 of the second panel support profile members 50b.

(53) Alternatively, the first and second panel support profile members 50a, 50b are slid into position whereby second arm 55 of first panel support profile member 50a is seated within the u-shaped receiving channel defined by bridging portion 57, first arm 53 and projecting member 53a of the second panel support profile members 50b; and projecting member 53a of first panel support profile member 50a is seated within the recess defined by side section 57b and second arm 55 of the second panel support profile members 50b.

(54) In either method, the weight of the cladding panel forces first and second panel support profile members 50a, 50b into the interlocking position. The advantage of the present invention is that is provides a fastening system that is quick and easy to install for the end user.

(55) FIGS. 10A-10D depict a further embodiment of a guide device 300. Similar to the guide devices 100, 200 described above, the guide device 300 includes a hollow body 2 having a first end 4, a second end 6, and a continuous section 8 intermediate the first end 4 and the second end 6. Similar to the guide device 200, the second end 6 of the guide device 300 has a generally hexagonal cross-sectional profile, including a plurality of apertures 24 distributed radially about the second end 6 on faces 24a of the hexagonal second end 6. A locating section 20 similarly comprises an indent 22 on sides 22a of the second end 6, such that the second end 6 can be seated securely within the fixing apertures 52 of the profile 50 depicted in FIGS. 7 and 8.

(56) The first end 4, second end 6, and continuous section 8 of the guide device 300 may be attachable and detachable sections. As shown in the exploded view of FIG. 10D, the continuous section 8 may be inserted through the second end 6 and into the first end 4 along a longitudinal axis 2d to form the assembled guide device 300. The first end 4 includes an internal stop 4a and internal threading 4b within its interior opening. The second end 6 has an internal opening that narrows at interior wall 6a. The continuous section 8 includes a collar 8c and external threading 8b compatible with the internal threading 4b of the first end 4. Thus, when the continuous section 8 is inserted through the second end 6, the collar 8c is restricted from traveling beyond the interior wall 6a of the second end 6. The continuous section 8 and the first end 4 can be coupled together by engaging the external threading 8b and the internal threading 4b such that the continuous section 8 is rigidly secured to the first end 4. The internal stop 4a can block the continuous section 8 from traveling beyond a desired distance into the first end 4. For example, the internal stop 4a may be located at a distance of between 0.125 and 0.25 from the continuous section receiving end of the first end 4. In some embodiments, the threaded portion of the continuous section 8 may be as long as or slightly longer than the length of the internal threaded portion of the first end 4. For example, if the first end 4 contains a threaded section 0.25 long adjacent to the internal stop 4a, the continuous section 8 may have external threading 8b along approximately 0.25 to 0.3 of its exterior surface.

(57) When assembled, certain components of the guide device 300 may be movable. In the example configuration of guide device 300, the first end 4 and the continuous section 8 may be rigidly attached, while the second end 6 may be able to rotate freely about the longitudinal axis 2d. The second end 6 may further be able to slide freely along the longitudinal axis 2d between the collar 8c and the body of the first end 4. Drill bit securing apertures 4c are provided in the first end 4 such that the first end 4 may be secured to a drill bit disposed at least partially within the guide device 300 along the longitudinal axis 2d. For example, the drill bit securing apertures 4c may have internal threading such that the drill bit may be secured by set screws or any other mechanical fixing means inserted through the drill bit securing apertures 4c. Thus, in use, the second end 6 may remain in a fixed position and orientation (e.g., with the locating section 20 inserted into a fixing aperture 52 of a profile 50), while the first end 4 and continuous section 8 rotate along with the drill bit as a hole is drilled.

(58) In some embodiments, the fixing of a portion of the guide device 300 to the drill bit itself may be advantageous by providing for precise depth control and eliminating any requirement to use a separately attached drill bit collar on a drill bit being used to drill holes in a substrate. The securing location of the first end 4 along a drill bit can be determined such that, when the second end 6 is abutting the first end 4, the drill bit extends beyond the second end 6 by a distance equal to the depth of the hole to be drilled. With the first end 4 secured to the drill bit in this position, the drill bit may be prevented from drilling a hole deeper than the desired depth into the substrate. Accordingly, the guide device 300 may provide precise depth control by incorporating the functionality of a drill bit collar.
