Abstract

A rotatable cutting bit which comprises an elongate bit body which has a forward end (37) and a rearward end and which defines a peripheral surface (42). The bit body contains a first seat (46) at the axially forward end thereof. A first cutting insert (60) is mechanically retained in the seat so as to present a clearance cutting edge (72) which radially extends past the peripheral surface of the bit body. The first cutting insert has a leading cutting edge (80) disposed at a lead angle (C) between 50 degrees and 80 degrees.
