ABSTRACT:
A holder for a cutting tool bit in the form of an elongated block and an elongated tang is disclosed. The tang has provision for supporting a throw-away tip. The tang is generally rectangular in cross section and has an edge defining an acute angle and a cylindrical clamping member which has a flat wedge-like edge on one side. The clamping member is threaded to receive a headed screw that extends through said body, urging the surface into clamped relation with the edge of the tang. A jack screw is extended through the tang and engages the bottom of the blind hole for moving the tang in precise increments relative to the block.
