Abstract
A tool holder system for mounting a cutting tool to a drive unit of a cutting tool apparatus. The tool holder system has a collet having a longitudinal bore for receiving a tool and a collet holder having a longitudinal bore for receiving the collet and the tool received in the collet, and the collet holder is coupled to the drive unit of the cutting tool apparatus. The collet has a narrow slit extending through a wall thereof from an outer surface of the collet to its longitudinal bore and a force-receiving portion on the outer surface thereof which is spaced from the slit by a distance of less than 90 degrees. The collet holder includes at least one aperture aligned with the force-receiving portion for receiving at least one pressing member for pressing against the force-receiving portion to close the slit in the collet to clamp the collet around the tool substantially around its entire circumference so as to reliably and effectively retain the tool within the collet. The invention also includes structure for adjusting the collet holder both axially and radially with respect to the axis of rotation of the drive unit of the cutting tool apparatus to ensure that the tool is properl…
