To assemble the collet, gently insert the groove of the collet into the eccentric ring inside the nut, and then snap the collet into place. To disassemble the collet, tilt the collet to the side until it snaps out of the eccentric ring, and remove it from the nut.
Notice: In case of a Ø12.2 mm tool, do not use a Ø12–11 mm collet. Instead, use a Ø12.5–11.5 mm collet. (For general cutting applications, a Ø13–12 mm collet is usable.)
