ABSTRACT:
A cutting tool assembly consisting of a cutting bit and a mounting block assembly for fixing the bit on a rotating drum or the like which will retain the bit in the mounting block at very high drum rotational speeds, which will accommodate high impact force and minimize the resulting wear experienced by the bit at high drum rotational speeds, and which permits quick and simple replacement of the bit when required.
