DETAILED DESCRIPTION OF THE INVENTION
[0034] The following description is of exemplary embodiments that are presently contemplated for carrying out the present invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles and features of the present invention. The scope of the present invention is not limited by this description.
[0035] Referring to
[0036] In some embodiments, the body 102 can include a connector 104. The connector 104 can be configured to secure an insert 106. The insert 106 can be configured to perform work on a workpiece 1. The work can be a type of finishing. This can include cutting, turning, chamfering, de-burring, grooving, knurling, grinding, buffing, burnishing, polishing, etc. In some embodiments, the body 102 can be configured to engage to a rotatable drive 200 (e.g., a portable drill, a handheld drill, etc.). The rotatable drive 200 can also be part of an automatic machine tool (e.g., a lathe). For example, the body 102 may be configured to be part of a cartridge of tools for the automatic machine tool. In some embodiments, the rotatable drive 200 can be configured to engage the workpiece 1. A portion of the workpiece 1 may be inserted into a mouth 108 of the body 102. The rotatable drive can cause the tool 100 and/or the workpiece 1 to rotate. Rotating the tool 100 and/or the workpiece 1 can cause the insert 106 to make contact with at least a portion of the workpiece 1. Rotating the tool 100 and/or workpiece 1 can further cause the insert 106 to perform work on the workpiece 1.
[0037] The body 102 can be fabricated from a rigid material, such as tool steel or other metal. The body 102 can include a first end 110. The body 102 can include a second end 112. The first end 110 may include the mouth 108. The mouth 108 may oppose the second end 112 such that the second end 112 and the mouth 108 define a longitudinal axis 114. The second end 112 can be configured to engage with the rotatable drive 200. The rotatable drive 200 may be a drill, rotating motor, etc. The rotatable drive 200 can be electrically driven, air driven, etc. The second end 112 can be configured to be received by a securement means. In some embodiments, the securement means may be part of the rotatable drive 200. For example, the second end 112 may be configured to be received by a chuck (e.g., a securement means) of a drill (e.g., a rotatable drive 200). In some embodiments, the second end 112 can be configured as a shank extending from a portion of the body 102. The shank may extend from the body 102 along the longitudinal axis 114. The shank may have a cross section that is cylindrical, cubic, hexagonal, etc. A surface of the shank may be smooth, textured, toothed, etc. The cross section and/or surface texture of the shank may be selected to provide a better engagement with the securement means.
[0038] The first end 110 can include an elongated body with sidewalls 116. The sidewalls 116 may be conjoined with a stop 118. The mouth 108 may be formed by an opening located at an end of the body 102. The mouth 108 may be positioned to be opposite the stop 118 and in line with the stop 118 along the longitudinal axis 114. In some embodiments, the mouth 108, the stop 118, and the second end 112 can all lie within the longitudinal axis 114. The body may further include a workpiece aperture 120. The workpiece aperture 120 may extend from the mouth 108 to the stop 118. The workpiece aperture 120 may define a chamber 133 within the body 102. The first end 110 can be configured to receive at least a portion of the workpiece 1. For example, the workpiece 1 may be inserted through the mouth 108 to be received by the workpiece aperture 120. This may include at least a portion of the workpiece 1 lying within the chamber 133 defined by the workpiece aperture 120. In some embodiments, the workpiece 1 may be inserted through the mouth 108 and into the workpiece aperture 120 until a portion of the workpiece 1 abuts the stop 118. For example, the workpiece 1 may be inserted through the mouth 108 and into the workpiece aperture 120 until a distal end 2 of the workpiece 1 abuts the stop 118. As will be explained later, some embodiments can include an insert 106. Some embodiments of the tool 100 can be configured such that the distal end 2 of the workpiece 1 abuts the insert 106, thereby preventing the distal end 2 of the workpiece 1 from making contact with the stop 118. (See
[0039] Depending on the work to be performed, the workpiece 1 may be inserted into the body 102 so that the insert 106 performs work on the workpiece 1 as the workpiece 1 and/or the tool 100 are moved relative to each other (e.g., translatable relative to each other) along the longitudinal axis 114. This can include performing work on the workpiece 1 as the tool 100 and/or workpiece are rotated or not rotated. Some embodiments can be configured to allow the distal end 2 of the workpiece 1 to move towards the stop 118 without making contact with the stop 118. This can be achieved by the workpiece 1 abutting the insert 106, whereby the insert prevents any further movement of the workpiece 1 towards the stop 118. As will be explained later, this can also be achieved via use of a pin 124. In other embodiments, the distal end 2 of the workpiece 1 can be moved towards the stop 118 until the distal end 2 of the workpiece 1 abuts the stop 118.
[0040] The first end 110 can include an outer surface 3. A cross section of the first end 110 at the outer surface 3 can be cylindrical, cubic, hexagonal, etc. The first end 110 of the body can include an inner surface 122a and an outer surface 122b. It is contemplated for the cross section of the first end 110 at the inner surface 122a to be cylindrical, but other shapes such as cubic, hexagonal, etc. can be used. The chamber 133 formed by the workpiece aperture 120 can define an inner diameter ID spanning from subtending ends of inner surfaces 122a of the sidewall 116. The inner surfaces 122a of the sidewall 116 within the chamber 133 can form a chamber wall. The distance spanning from subtending points on the outer surface 122b can define an outer diameter OD. It is contemplated for the inner diameter ID to be greater than a cross sectional diameter of the workpiece 1, or at least the distal end 2 of the workpiece 1, that the body 102 is intended to receive. For example, if the cross sectional diameter of a distal end 2 of a workpiece is 10 mm, the inner diameter ID may be greater than 10 mm. It is contemplated for the tool 100 to be used for workpieces 1 having distal ends 2 with cross sectional diameters ranging from 1 mm to 1,000 mm. However, the tool 100 can be configured to perform work on workpieces 1 with any length of cross sectional diameter. It is contemplated that for larger workpieces 1, the workpiece 1 and/or tool 100 may be held in fixed equipment suitable to the application. For example, the workpiece 1 may be held in a securement means of a lathe while the tool 100 is attached to a jig or some other mechanism that is connected to a rotatable drive 200 of the lathe.
[0041] A sidewall 116 can include a connector 104. The connector 104 can be configured to secure an insert 106 to the body 102. This can include removably securing or permanently securing the insert 106 to the body 102. In some embodiments, the connector 104 can be configured as a recess to receive and temporarily retain an insert 106. For example, the connector 104 can be a socket formed within the sidewall 116 to hold an insert 106 in place. In some embodiments, the connector 104 can be located on an inner surface 122a of the sidewall 116. For example, securing an insert 106 within the connector 104 can allow the insert 106 to be exposed to the chamber 133 formed by the workpiece aperture 120.
[0042] There can be more than one connector 104. Any connector 104 can be located at any location on the sidewall 116. It is contemplated for the insert 106 to perform work on the workpiece 1, and thus placement of the connector 104 may be dictated by the type of work expected to be performed. For example, the insert 106 may be used to form a groove in the workpiece 1 at a certain distance from the distal end 2 of the workpiece 1. In embodiments where the distal end 2 of the workpiece 1 is caused to abut against, or almost abut against, the stop 118, the distance along the longitudinal axis 114 from the stop 118 to the connector 104 can be used to determine where the groove may be formed on the workpiece 1. For instance, a distance from the stop 118 to the connector 104 can be X. If the workpiece 1 is inserted into the mouth 108 and through the workpiece aperture 120 so that its distal end 2 abuts, or almost abuts, the stop 118, the connector 104 can be located at a distance X from the distal end 2 of the workpiece 1. This may cause the insert 106 (when one is secured to the connector 104) to also be located at a distance X from the distal end 2 of the workpiece 1. Thus, when the tool 100 is used to perform work on the workpiece 1, the work can be performed at the distance X from the distal end 2 of the workpiece 1. For example, a groove can be formed in the outer surface 3 of the workpiece 1 at a distance X from the distal end 2 of the workpiece 1 by inserting the workpiece 1 into an embodiment of the tool 100 so that the distal end 2 abuts, or almost abuts, the stop 118 and where the distance from the stop 118 to the connector 104 is X. The tool 100, having an insert 106 secured to the connector 104, and/or the workpiece 1 can be caused to rotate. This can cause the insert 106 to generate a groove in the outer surface 3 of the workpiece 1 at the distance X from the distal end 2 of the workpiece 1.
[0043] As will be explained in detail later, some embodiments can include a pin 124. The pin 124 can be configured to allow the distal end 2 to almost abut the stop 118. For example, the pin 124 can be spring loaded to allow the workpiece 1 to move towards the stop 118 but cease the movement when the pin 124 is flush with, or approximately flush with, the stop 118. This may allow the distal end 2 to almost come into contact with the stop 118.
[0044] In addition to being located at any distance along the longitudinal axis 114, any connector 104 can be located at any radial location along the inner surface 122a. A radial location can be defined as a position point along a path following the inner surface 122a at a given position along the longitudinal axis 114.
[0045] Some embodiments can include a plurality of connectors 104. Any two or more connectors 104 can be located at a same or different distance along the longitudinal axis 114. For example, a first connector 104 can be located at a distance X from the stop 118. A second connector 104 can be located at a distance J from the stop, where J can be greater than or less than X. Any two re more connectors 104 can be located at a same or a different radial location along the inner surface 122a.
[0046] A connector 104 can be configured to secure an insert 106 so that the insert 106 makes contact with an outer surface 3 of the workpiece 1. This can include causing the insert 106 to make contact with the workpiece 1 without the workpiece 1 making contact with the inner surface 122a of the sidewall 116. In some embodiments, at least two connectors 104 can be positioned at different radial locations so as to cause the inserts 106 secured therein to both make contact with an outer surface of the workpiece 1. This can include preventing the outer surface of workpiece 1 from making contact with the inner surface 122a of the sidewall 116. For example, a first connector 104 can be positioned so as to subtend a second connector 104 (e.g., be 180-degrees from each other). The workpiece 1 may be bound by the inserts 106 of the 180-degree separated connectors 104 so as to prevent the outer surface 3 of the workpiece 1 from making contact with the inner surface 122a of the sidewall 116. More than two connectors 104 can be used for this purpose. Furthermore, other radial locations and degrees of separation can be used for this purpose.
[0047] Alternatively, a connector 104 can be configured to secure an insert 106 so that the insert 106 makes contact with the outer surface 3 of the workpiece 1, where the outer surface 3 near the distal end 2 of the workpiece 1 does not make contact with the inner surface 122a of the sidewall 116 but the outer surface 3 of the workpiece 1 is capable of making contact with a portion of the inner surface 122a at or near the mouth 108. This can allow the workpiece 1 to be held approximately parallel to the longitudinal axis 114. In some embodiments, the mouth 108 of the body 102 can include a buffer ring 126. The buffer ring 126 can be an annular element configured to fit within the chamber 133. The buffer ring 126 can have an opening that may be configured to allow the workpiece 1 to be slid therethrough. The buffer ring 126 may be configured such that the outer surface 3 of the workpiece 1 at or near the mouth 108 can make contact with the buffer ring 126. The contact with the buffer ring 126 can allow the workpiece 1 to be held approximately parallel to the longitudinal axis 114. The buffer ring 126 can be fabricated from a material that is softer than that of the workpiece 1. The buffer ring 126 may be replaceable. In some embodiments, the buffer ring 126 can be sacrificial. In some embodiments, the buffer ring 126 can include a bearing race. This may allow the buffer ring 126 to rotate independently and freely with respect to the tool.
[0048] As the tool 100 and/or workpiece 1 is caused to rotate and/or caused to move along the longitudinal axis 114, the outer surface of the workpiece 1 at or near the mouth 108 can make contact with the inner surface 122a and/or the buffer ring 126. The workpiece 1 may be bound by the inserts 106 so as to prevent an outer surface 3 of the distal end 2 of the workpiece 1 from making contact with the inner surface 122a of the sidewall 116 at or near the stop 118 while the tool 100 and/or workpiece 1 is caused to rotate and/or caused to move along the longitudinal axis 114. In some embodiments, the workpiece 1 may be bound by the inner surface 122a at or near the mouth 108 and/or the buffer ring 126 so as to hold the workpiece 1 approximately parallel to the longitudinal axis 114 while the tool 100 and/or workpiece 1 is caused to rotate and/or caused to move along the longitudinal axis 114.
[0049] Some connectors 104 can secure an insert 106 so that the insert 106 forms an angle that is normal, oblique, or acute to an outer surface 3 of the workpiece 1. This can include configuring the connector 104 so that is secures an insert 106 so that it forms an angle that is normal, oblique, or acute to the longitudinal axis 114.
[0050] Embodiments of the tool 100 with a plurality of connectors 104 can be used with each connector 104 having an insert 106 secured therein, with only some connectors 104 having an insert 106 secured therein, or only one connector 104 having an insert 106 secured therein.
[0051] Referring to
[0052] The workpiece 1 may be a billet, a pipe, a rail, a rod, a bar, a tube, an engine part, piece of hardware, etc. The workpiece 1 may include metal, wood, ceramic, plastic, polycarbonate, etc. The material and/or configuration of the head 130 may be selected based on the type of material of the workpiece 1 and/or the type of work to be performed on the workpiece 1.
[0053] As noted above, the connector 104 may be configured to secure an insert 106 so that the insert 106 forms an angle that can be normal, oblique, or acute to the longitudinal axis 114. In addition, or in the alternative, the head 130 can be angled with respect to the shaft 128 so that the head 130 can form an angle that is normal, oblique, or acute to the longitudinal axis 114. Causing the insert 106 and/or the head 130 of the insert 106 to form an angle that is normal, oblique, or acute to the longitudinal axis 114 can be done to cause the insert 106 and/or the head 130 of the insert 106 to form an angle that is normal, oblique, or acute to an outer surface of the workpiece 1. This may be done to facilitate performing a type of work.
[0054] Additionally, or in the alternative, the body 102 may be machined to receive and hold a different degree insert 106, such as a 60-degree, 45-degree, or other degree insert 106. In some embodiments, the inner and/or outer surfaces 122a, 122b of the sidewalls 116 can be modified to accommodate holding an insert 106 at a certain angle with respect to the longitudinal axis 114. For example,
[0055] For instance, the tool 100 may be used to generate a chamfer at a distal end 2 of the workpiece 1. (See
[0056] As another example, the head 130 of the insert 106 may be at any angle, including an angle that is normal to the outer surface of the workpiece 1. The workpiece 1 may be inserted through the mouth 108 and into the workpiece aperture 120. The insert 106 can be positioned so that it makes contact with an outer surface 3 of the workpiece 1 at the distal end 2 of the workpiece 1. The insert 106 can be configured so that it can remove a portion of the workpiece 1 at the outer surface 3. The tool 100 and/or workpiece 1 may then be caused to rotate via the rotatable drive 200. The workpiece 1 and/or tool 100 may be caused to move along the longitudinal axis 114. For example, the workpiece 1 may be caused to move in the rearward direction 132 and/or the tool 100 may be moved in the forward direction 134. This can cause the insert 106 to cut the workpiece 1 at the distal end 2 of the workpiece 1 to remove a corner 4 of the workpiece 130. The workpiece 1 can be moved in the rearward direction 132 until a desired portion of the corner 4 is removed, thereby forming the chamfer cut.
[0057] Referring to
[0058] Some embodiments can include a set of inserts 106, each insert 106 having a different shaft-length, head-configuration, shaft-head angle, etc. For example, a set may include a first insert 106 having a head 130 configured for cutting, a second insert 106 having a head 130 configured for de-burring, a third insert 106 having a head 130 configured for polishing, etc. The workpiece 1 can be first cut via the first insert 106. After cutting the workpiece 1 with the first insert 106, the first insert 106 can be removed from the body 102. The second insert 106 can be secured to the body 102. The workpiece 1 can then be de-burred via the second insert 106. After de-burring the workpiece 1 with the second insert 106, the second insert 106 can be removed from the body 102. The third insert 106 can be secured to the body 102. The workpiece 1 can then be polished via the third insert 106.
[0059] Referring to
[0060] For example, the first insert 106 (having shaft 128 length Y) can be secured to a first connector 104. The tool 100 can be used for turning, as described herein, to generate the first region 5a of reduced cross sectional diameter at or near the distal end 2 of the workpiece 1, the reduction of cross sectional diameter corresponding to the shaft length of Y. The first insert 106 can be removed from the first connector 104. The second insert 106 (having shaft 128 length of Z) can be secured to a second connector 104. The second connector 104 can be located on the body at a distance from the stop 118 and/or pin 124 that is less than the distance from the stop 118 and/or pin 124 the first connector 104 is located. The tool 100 can again be used for turning, as described herein, to generate a region 5b of reduced cross sectional diameter at or near the distal end 2 of the workpiece 1, the reduction of cross sectional diameter corresponding to the shaft length of Z. Thus, the workpiece 1 can be worked to have two regions 5a, 5b of reduced cross sectional diameter.
[0061] As another example, the first insert 106 (having shaft 128 length Y) can be secured to a connector 104. The tool 100 can be used for turning, as described herein, to generate a region 5 of reduced cross sectional diameter at or near the distal end 2 of the workpiece 1, the reduction of cross sectional diameter corresponding to the shaft length of Y. The first insert 106 can be removed from the connector 104. The second insert 106 (having shaft 128 length of Z) can be secured to the same connector 104. The tool 100 can again be used for turning, as described herein, to generate a reduced cross sectional diameter at or near the distal end 2 of the workpiece 1 within the same region 5, the reduction of cross sectional diameter corresponding to the shaft length of Z. Thus, the workpiece 1 can be worked to have a single region of reduced cross sectional diameter, but the reduction in diameter can occur in stages.
[0062] As another example, the first insert 106 can be secured to the first connector 104 and the second insert 106 can be secured to the second connector 104 to perform turning. The workpiece 1 can be inserted into the mouth 108 of the body 102 until the distal end 2 makes contact with the second insert 106. The tool 100 and/or workpiece 1 can be caused to rotate. The workpiece 1 and/or tool 100 can be caused to move along the longitudinal axis 114. This can include causing the workpiece 1 to move in the rearward direction 132 and/or causing the tool 100 to move in the forward direction 134, thereby generating the first region 5a of reduced cross sectional diameter on the workpiece 1. The workpiece 1 can be further moved in the rearward direction 132 and/or the tool 100 can be further moved in the forward direction 134 until the distal end 2 of the workpiece 1 makes contact with the first connector 104. At this point, the first region 5a may be partially formed. The workpiece 1 can be further moved in the rearward direction 132 and/or the tool 100 can be further moved in the forward direction 134, thereby generating the second region 5b of reduced cross sectional diameter on the workpiece 1 by the second insert 106 as the first insert continues to generate the first region 5a. Thus, the workpiece 1 can be worked to have two regions of reduced cross sectional diameter without having to interchange any inserts 106.
[0063] Other implementations and permutations of performing work and/or interchanging inserts 106 can be done to achieve a desired type of work on the workpiece 1. For example, some embodiments can be used to generate more than two regions of reduced cross sectional diameter. This can be achieved by using more than two inserts 106 of different shaft lengths. Some embodiments can include performing multiple types of work. This can be achieved by interchanging inserts 106 to perform the type of work. As noted above, some implementations can allow for simultaneous working without having to interchange inserts 106. This can be achieved by using the tool 100 with a first insert 106 in a first connector 104 and a second insert in a second connector 104, where the first insert 106 and the second insert 106 perform work on the workpiece 1 as the tool 100 and/or workpiece 1 is caused to rotate and/or move along the longitudinal axis 114.
[0064] Some embodiments can include more than two inserts 106. Any first insert 106 may be the same as or different from a second insert 106. Any second insert 106 can be the same as or different from a third insert 106 or the first insert 106. Any third insert 106 can be the same as or different from a fourth insert 106, the second insert 106, or the first insert 106. And so on. The first insert 106 may be configured to perform the same or different type of work as the second insert 106, the third insert 106, the fourth insert 106, etc. The first insert 106 may be located at a same or different radial location along the inner surface 122a and/or the same or different distance along the longitudinal axis 114 as that of the second insert 106, the third insert 106, the fourth insert 106, etc.

[0066] The port 136 may further allow for discharge of work by-product. For example, as work is being performed on the workpiece 1, work by-product, such as swarf, chips, turnings, filings, shavings, etc.) can be generated. The work by-product may be collected within the chamber 133. The work by-product may be extracted through the port 136. This may be done to allow for the escape of the work by-product (e.g., drilling chips) so that they do not bind and/or damage the workpiece 1 or a surface of the workpiece 1. Discharging the work by-product can be achieved by reaching into the port 136 and pulling the work by-product out from the chamber 133. This can also be achieved by using forced air (e.g., forced air form a compressed air source) to blow out the work by-product. This can also be achieved by positioning the tool 100 so that the work by-product falls from the port 136. In some embodiments, the work by-product can be expelled from the chamber 133 via the port 136 automatically. This can be achieved by the centrifugal force acting on the work by-product as the tool 100 is caused to rotate, where the centrifugal force may cause the work by-product to be expelled from the port 136.
[0067] Some embodiments, at least one through-hole 142 can be provided. The through-hole 142 can extend from the outer surface 122b of the sidewall 116 to an inner surface 122a of the sidewall 116. The through-hole 142 may lead to a portion of the chamber 133 where the port 136 is located. The through-hole 142 can facilitate holding the insert 106 in place. For example, the through-hole 142 may be threaded to receive a threaded bolt. The threaded bolt may be inserted into the through-hole 142 and advanced radially inward toward an insert 106 that has been placed in the connector 104. The threaded bolt may be advanced until it makes contact with the insert 106. This may include holding the insert 106 in position.

[0069] In some embodiments, the buffer ring 126 can extend beyond the mouth 108. This may be done to provide a protective barrier between the first end 110 of the body 102 and a portion of the workpiece 1. For example, the workpiece 1 may be part of another object. The tool 100 can be used to perform work on the workpiece 1 while the buffer ring 126 portion that extends beyond the mouth 108 can prevent the tool 100 from making physical contact with the object to which the workpiece 1 is attached. For example, the buffer ring 126 can make contact with the object of the workpiece 1 so that it prevents the first end 110 from making contact with the object. As noted above, the buffer ring 126 may be made of material that is softer than that of the workpiece 1. This can include being softer than the object to which the workpiece 1 is attached.

[0071] The length of the pin 124 can be such that, as the pin 124 traverses a path along the longitudinal axis 114, the pin distal end 146 can protrude into and/or be retracted from the chamber. For example, when the pin head 130 abuts the mechanical stop, the pin distal end 146 may protrude into the chamber 133. When the pin 124 is moved in the rearward direction 132, the pin distal end 146 can be caused to move out from the chamber 133 and into the pin aperture 144.
[0072] In some embodiments, a spring 154 can be placed within the bore 150. This can include positioning the spring 154 between the distal end 152 of the shank and the pin head 148. This can be done to bias the pin 124 in the forward direction 134. This can further include biasing the pin 124 in the forward direction 134 so that the pin distal end 146 protrudes into the chamber 133. This can further include biasing the pin 124 in the forward direction 134 so that the pin distal end 146 protrudes into the chamber 133 unless the pin 124 is acted upon so as to cause the pin 124 to move in the rearward direction 132. In some embodiments, the spring 154 can be configured to prevent the pin distal end 146 from being retracted into the pin aperture 144 but still allow movement of the pin 124 in the rearward direction 132. This can include allowing the pin 124 to be moved in the rearward direction 132 until the pin distal end 2 is flush or approximately flush with the stop 118. This may be done to prevent the distal end 2 of the workpiece 1 from making contact with the stop 118.
[0073] In some embodiments, the pin 124 can freely rotate within the pin aperture 144. This may be done to allow the distal end 2 of the workpiece 1 to abut against a non-rotating member as the tool 100 and/or workpiece 1 is caused to rotate. This may prevent unwanted work and/or damage being done to the distal end 2 of the workpiece 1. For example, as the tool 100 and/or workpiece 1 is rotated to perform work on the workpiece 1, the workpiece 1 and/or tool 100 may be caused (intentionally or inadvertently) to move relative to each other along the longitudinal axis 114. The distal end 2 of the workpiece 1 may abut against the pin distal end 146 as opposed to abutting against the stop 118. In some embodiments, the pin 124 and the workpiece 1 may remain stationary (with respect to rotational motion) while the tool 100 is caused to rotate. In some embodiments, the pin 124 may be caused to rotate with the workpiece 1 as the workpiece 1 is caused to rotate. The spring 154 can allow the pin distal end 146 to move forward 134 and/or rearward 132 so as to facilitate a desired type of work. For example, allowing the pin 124 to move forward 134 and/or rearward 132 can allow the workpiece 1 to be moved relative to the tool 100 along the longitudinal axis 114. As noted above, in some embodiments, the spring 154 may be configured to prevent the pin distal end 146 from being retracted into the pin aperture 144. This may include allowing the pin distal end 146 to move rearward 132 until it is flush or approximately flush with the stop 118. This may allow the workpiece 1 to be moved up to the stop 118 without making physical contact with the stop 118.
[0074] In some embodiments, the pin distal end 146 can include a pad 156. The pad 156 can include a material that is softer than that of the workpiece 1. This can be done to provide protection to the workpiece 1 when the workpiece makes contact with the pad 156.
[0075] In some embodiments, the pin 124 and/or the spring 154 can be secured within the bore 150 via a cap 158. For example, the cap 158 can be configured to removably secure to the distal end 152 of the shank. This can be achieved by the cap 158 being threaded so that it can threadingly engage with threading of the bore 150. This may be done to facilitate interchangeability and/or replacement of the pin 124 and/or spring 154.
[0076] While exemplary embodiments may describe the tool 100 being rotated via a rotatable drive 200, other implementations can be used. For example, the workpiece 1 can also be caused to rotate via a rotatable drive 200. This can include causing the workpiece 1 to rotate while holding the tool 100 stationary. For example, the second end 112 of the tool 100 can be secured so as to remain stationary. The workpiece 1 can be inserted into the tool 100 via the mouth 108. The workpiece 1 can then be caused to rotate via the rotatable drive 200. In some embodiments, the workpiece 1 and the tool 100 can be caused to rotate with separate rotatable drives 200. This can include causing the workpiece 1 to rotate in one direction while causing the tool 100 to rotate in another direction. This can further include causing the workpiece 1 to rotate in a same direction as the tool 100 but at a different rotational speed. Rotation of the tool 100 and/or the workpiece 1 can be along the longitudinal axis 114.
