Milling chuck Collet sets

Insert groove of collet into eccentric ring of the clamping nut at the mark on the bottom of the nut. Push collet in the directionof the arrow until it clicks in place. Screw nut with collet onto tool holder. We recommend tightening the nut with a torquewrench.

After the nut is unscrewed from the toolholder, press on the face of the collet while simultaneously pushing sideways on the back of the collet opposite the mark until it disengages from the clamping nut.
