Abstract
A deformed sleeve for mounting a cutting tool in a bit holder has one end shaped as an ellipse. The deformation is done by the application of pressure before heat treating. No further machining is necessary after the heat treatment. The deformed sleeve is force-fitted into a bore in a bit holder and is retained therein in a non-rotating manner by friction.
