An asymmetrical corner joint in a material having a planar surface, in which one side of the joint is shaped to be a slanted plane and the other side of the joint is shaped to be a beveled plane and a shoulder plane, such that when the joint is formed the slanted plane and beveled plane abut and the shoulder plane abuts a portion of the planar surface adjacent the slanted plane. A tool set for use with a router for shaping the two sides of the asymmetrical corner joint in one pass, the tool set including a bit with an angle cutting portion and a shoulder cutting portion, and a canting base for use with the router for tilting the angle of rotation of the bit such that the angle cutting portion cuts both sides of the cut and the shoulder cutting portion only cuts one side.

A coping cut machine can include a workpiece platform having a support surface for receiving a workpiece support surface. The coping cut machine can have first and second rotary cutting devices, each supporting at least one knife, and at least one workpiece alignment member supported by the workpiece platform for aligning a workpiece supported by the workpiece platform relative to at least one of the first and second rotary cutting devices. In response to sliding the workpiece along the at least one workpiece alignment member and during rotation of at least one of the first and second rotary cutting devices, the at least one knife operates to perform a coping cut on an end of the workpiece. The first and second rotary cutting devices can optionally be rotated in opposite directions to cut either end of a workpiece. At least one of the first and second rotary cutting devices can comprise a modular rotary cutting assembly having a keyed profile portion received in a keyed profile aperture of a drive wheel, and that is removable from the coping cut machine.

A groove processing apparatus of processing a groove having a triangular cross section in a side of a plate material is provided. The groove processing apparatus includes a cutting member, a first driving part and a second driving part. The cutting member cuts the side of the plate material and the first driving part moves the cutting member to first and second positions. The second driving part moves the cutting member in groove processing directions of the plate material. The first position corresponds to any one of the two sides of the triangular shape having the same vertex and the second position corresponds to the other thereof, and the vertex is positioned inside the plate material.

An apparatus (1300), including: a shaper cutter head (1308) having: a body (1312); a bore (1314) through the body; and a cutter 1310) secured to the body. Along a longitudinal axis (1306), the cutter has: a miter profile, a groove profile and a tongue profile for cutting a miter. The body has a portion (1352) comprising a recess (1320) disposed between the miter profile of the cutter and an end of the body. The recess defines a flat indexing surface (1326) protruding radially outwards from a portion of the body. When the shaper cutter head is rotated about the longitudinal axis, the body defines a body sweep (1360). The flat indexing surface is recessed from the body sweep.
