The current invention provides apparatus and a method for use with a drill bit to form a hole in a workpiece, said apparatus including a clamping means to clamp a workpiece in which the hole is to be formed in position with the apparatus, a drill bit holder assembly and drive means for rotating the drill bit and moving the same into the workpiece so as to drill the hole at a required angle and depth into the workpiece. Typically the depth of the hole is set in relation to the thickness of the workpiece which is clamped in position at that time and the apparatus includes a first part which is held by a first hand of the user and movable by the user with respect to a second part which is held by a second hand of the user and the relative movement is translated into movement of the drill bit holder to move the rotating drill bit into the workpiece.

In an embodiment, a pocket hole jig is provided having a base, a lever, a clamp, a drill bit guide and a rack and pinion system. The rack and pinion system is configured to automatically adjust the pocket hole jig according to a position of the lever and the clamp.

A gauge plate is configured to drill at least one accommodation hole in at least one size by using a square reamer. The gauge plate contains: at least one alignment orifice defined thereof and corresponding to the at least one size so as to accommodate the square reamer in the at least one accommodation hole. The gauge plate contains four L-shaped slots formed on four corners thereof, corresponding to the at least one alignment orifice, and configured to define the at least one size of the at least one accommodation hole. The gauge plate further contains multiple V-shaped notches defined on the four peripheral sides thereof and corresponding to the four alignment orifices and the four T-shaped slots, and a size value portion is configured to display three size values.

A colleted bushing includes a collet and a bushing. The collet has a collet proximal end and a collet bore having collet threads. In addition, the collet has a collet bore taper located adjacent the collet proximal end, and a plurality of collet fingers located adjacent the collet proximal end and configured to be inserted into a workpiece hole of a workpiece. The bushing has a bushing proximal end, a bushing bore, a bushing outer surface, and bushing threads formed along a section of the bushing outer surface. The bushing is configured to be inserted into the collet bore and the bushing threads are configured to engage the collet threads in a manner resulting in movement of the bushing proximal end into contact with the collet bore taper causing the collet fingers to be urged radially outwardly and removably locking the collet within the workpiece hole.

A general purpose hole saw guide and a method of forming holes through surfaces, without the need of a centering bit, are provided. The hole saw guide includes a circular disk with concentric grooves on its surface. The disk is transparent and portable for placement on a surface through which a hole is to be drilled to facilitate the centering and stabilizing control of a hole saw on the surface. The method includes the steps of providing a transparent disk having concentric grooves; positioning the disk on a surface; mounting the disk to the surface; inserting a hole saw that is fitted to a drill into the grooves of the disk; drilling a hole through the disk and surface beneath it; and removing the disk from the surface after the hole has been drilled.

A pocket hole jig for locating pocket holes in a workpiece includes a base with a base plate and first and second side walls extending along the base plate, and a body disposed between the first and second side walls and slidable along the base in a forward direction and a rearward direction. The body includes a drill bit aperture angled downward toward the base plate. The pocket hole jig also includes a fastener configured to releasably couple the pocket hole jig to an adjacent second pocket hole jig.

A pocket hole jig includes base with a base plate and first and second lateral side walls extending along the base plate, and a body disposed between the first and second lateral side walls and slidable along the base in a forward direction and a rearward direction. The body includes a drill bit aperture angled downward toward the base plate. The pocket hole jig also includes a fence movable between a raised position and a lowered position and having a contact surface engageable with an end of the workpiece when the fence is in the lowered position to position the base a predetermined distance from the end of the workpiece. The contact surface is in a first position when the fence is in the raised position and a second position when the fence is in the lowered position. The second position is forward of the first position.

In an exemplary embodiment, a template for locating and drilling one or more holes in a door is provided. The template may include a body member having a first side portion, a second side portion, and a middle portion. The middle portion can be between the first side portion and the second side portion forming a profile that is configured to cooperatively engage with a portion of the door. The profile can include at least one curved portion to correspond to a curved portion of the portion of the door.

A pocket hole jig contains: a body, a holder, and a fitting sleeve. The body includes at least one accommodation orifice configured to house a driller, each accommodation orifice tilts downwardly and extends toward a bottom of the body, wherein the body also includes a first marking portion arranged on a first side surface thereof. The holder includes an operation room in which the body is fitted and moves relative to the holder, at least one through groove formed on a bottom of the holder so as to correspond to the at least one accommodation orifice, and a first scale section arranged on a first side surface thereof and aligning with the first marking portion. The fitting sleeve is fitted with the driller, and the holder further includes a depth scale section for measuring depths of holes drilled on wooden workpieces by the driller.

A mono-stable self-aligning template for installing brackets and treatments around an opening has a first plate having a top surface, a bottom surface, a front edge, a rear edge and a pair of opposing side edges. A plurality of openings is formed through the top surface of the first plate. The plurality of openings is arranged in at least a first array on a first side area on the top surface of the first plate. A mono-stable self-alignment device is coupled to the first plate. The mono-stable self-alignment device is perpendicular to the first plate.
