摘要

A cutting tool including a base having a turntable mounted thereon for rotation about a vertical axis. The base has a surface including a first detent portion at a predetermined position, and a second detent portion mounted on the turntable and being selectively engageable with the first detent portion to releasably secure the turntable in a predetermined position of angular adjustment relative to the base. The cutting tool also includes a spring biasing the second detent portion against the base surface, and a lever movable with the turntable to move the second detent portion to a withdrawn position allowing angular adjustment of the position of the turntable about the predetermined position of angular adjustment of the turntable relative to the base.
