M32 3-1/4" Cone Master Collet
The Martin Master collet has a slot in the face of the collet that goes through to the head angle to allow pads to be clamped into place. Pads are held in the collet using a square lug which is threaded into the pad and secured by a taper-threaded locking screw. The collets do not have to be removed from the spindle to change the pads. The clamps stay with the pads and cannot be lost.
