ABSTRACT:
An improved collet tool holder is disclosed characterized by use of formed cam surfaces upon the collet and tightening sleeve of the tool holder. Selective rotation of the sleeve relative to the collet causes selective, ramping, engagement of the complementary cam surfaces which causes selective compression of the collet to securely grip a cutting tool. The collet's internal aperture may optionally present a formed cam surface which engages a complementary cam surface formed upon the shank of the cutting tool.
