A linearly and angularly adjustable holder for a cutting tool having primary and secondary cutting edges includes a basic element, a receptacle element for the cutting tool rotatably mounted on the basic element, and a setting element slidably mounted on the basic element. The receptacle element is mounted on the basic element so as to be pivotal about the point of intersection of the primary and secondary cutting edges of the cutting bit. An adjustment screw 50 whose threaded portion is seated in the basic element and whose head engages a recess in the receptacle element serves to perform the angular adjustment. The linear adjustment is accomplished with the aid of a double threaded adjustment screw which connects a wedge and the basic element and which slidably engages the setting member to control the length of the holder. |
