Abstract: A subassembly is provided for a pipe lathe. The pipe lathe includes a segmented base ring and a drive gear assembly. The segmented base ring is structured to be removably coupled to a work piece having a perimeter. The subassembly includes a gear ring, a separate ring member, at least one tool mounting portion disposed on the separate ring member. The separate ring member is fastenable to the gear ring, in order that the separate ring member rotates with the gear ring but not independently with respect thereto. A number of tool assemblies mount to the tool mounting portion to machine the work piece. The gear ring includes a plurality of teeth, which cooperate with the drive gear assembly of the pipe lathe to rotate the subassembly about the perimeter of the work piece.

The segmented base ring is structured to be removably coupled to a work piece having a perimeter. The subassembly includes a gear ring, a separate ring member, at least one tool mounting portion disposed on the separate ring member, and a plurality of fasteners. The fasteners extend through the apertures of the separate ring member and fasten the separate ring member to the gear ring, in order that the separate ring member rotates with the gear ring but not independently with respect thereto.

Abstract: An indexable cutting insert for beveling a pipe end, and having a first quadrilateral surface and a second quadrilateral surface in spaced, generally parallel relationship to each other separated by a non-parallel planar sidewall comprised of four side flank portions defined as a portion of the sidewall extending from one corner of the insert to an adjacent corner of the insert. The non-parallel sidewall and both the first and second surfaces define intersecting cutting edges. A related method is also disclosed.
