Chamfer-cutting tools

A chamfer-cutting tool kit, wherein the chamfer-cutting tool kit is configured to be selectively assembled into an upper-chamfer configuration for cutting an upper chamfer between an upper face of a workpiece and an edge face of the workpiece adjacent to the upper face, and wherein the chamfer-cutting tool kit is further configured to be selectively assembled into a lower-chamfer configuration for cutting a lower chamfer between the edge face of the workpiece and a lower face of the workpiece adjacent to the edge face and opposite the upper face, the chamfer-cutting tool kit comprising:

• a cutter comprising a shaft and a conical cutting surface, wherein the shaft comprises a first end and a second end opposite the first end, and wherein the shaft defines a cutter rotation axis, wherein the first end is configured to be operatively coupled to a motor when the chamfer-cutting tool kit is assembled into the upper-chamfer configuration, and wherein the second end is configured to be operatively coupled to the motor when the chamfer-cutting tool kit is assembled into the lower-chamfer configuration;
• a bushing comprising an outer cylindrical contact surface configured to engage and operatively roll along the edge face of the workpiece, wherein the bushing is configured to be rotatably coupled to the shaft between the conical cutting surface and the second end of the shaft when the chamfer-cutting tool kit is assembled into the upper-chamfer configuration and when the chamfer-cutting tool kit is assembled into the lower-chamfer configuration;
• an upper-edge guide block configured to be selectively coupled relative to the cutter when the chamfer-cutting tool kit is assembled into the upper-chamfer configuration, wherein the upper-edge guide block comprises an upper-face guide surface configured to engage the upper face of the workpiece, wherein a position of the upper-edge guide block is configured to be selectively adjusted along the cutter rotation axis relative to the conical cutting surface of the cutter and relative to the outer cylindrical contact surface of the bushing to selectively define a first chamfer cutting region of the conical cutting surface between the upper-face guide surface and the outer cylindrical contact surface of the bushing;
• and
• a lower-edge guide block configured to be selectively coupled relative to the cutter when the chamfer-cutting tool kit is assembled into the lower-chamfer configuration, wherein the lower-edge guide block comprises a lower-face guide surface configured to engage the lower face of the workpiece, wherein a position of the lower-edge guide block is configured to be selectively adjusted along the cutter rotation axis relative to the conical cutting surface of the cutter and relative to the outer cylindrical contact surface of the bushing to selectively define a second chamfer cutting region of the conical cutting surface between the lower-face guide surface and the outer cylindrical contact surface of the bushing.
