What is the taper angle of a collet holder?
This collet as a taper angle of 6°, the ideal angle for run-out accuracy, gripping force and rigidity. The increased number of slits ensures the uniform tightening and high accuracy of the collet. The collet holder (CTH type) is pre-balanced by previously designing the holder to be as axisymmetrical as possible.
