ABSTRACT:
A rotary cutting tool having a shank and a head at one end of the shank, the head having a flat bed portion. A clamp for carrying a bit is mounted for rotation on the bed portion for angular adjustment of the bit relative to the bed portion. This clamp has a groove in one of its faces, the bit being axially slidable therein to different extended positions, and the groove has a depth less than the thickness of the bit such that the bit projects laterally from the groove for engagement with the bed portion. As the clamp is drawn toward the bed portion, the bit is clamped in the groove against the bed portion in any predetermined adjusted angular and extended position.
