A holder body 10 has a slender extension 11 provided with a V-shaped seat 12 for a similarly notched cutting bit 13. The tapered leg 18 of a reversible L-shaped clamp 19 bears against a recess 16 in the bit. A rear shoulder 21 in the holder body provides a fulcrum for the clamp, which is fastened to the body and urged against a rear face 22 thereof by a screw 26 engaging slightly offset holes 24 and 27 in the clamp and body, respectively. |
