Percussive tools.-The cutter 1 of a pneumatic pick or like tool is attached to the body by means of a T-headed socket 5 engaging a recess 2 in the cutter and held by a pin 9, the end 4 of the socket being screwed to the body of the tool. Sufficient longitudinal play is left for the bit to move forward as shown in Fig. 4 on an idle blow, or for controlling an automatic stop. The parts of the cutter may be soldered, welded or riveted.
