After removing the cutting tool from the MAXIN, the clamping nut must be unscrewed one extra turn to prevent reduction of the clamping power and to ensure maximum gripping force. Preset screw in order to adjust the projection length of the cutting tool you can use a preset screw inside the MAXIN internal bore part #9. This is supplied as an optional accessory. Insertion of SC collets and shanks. The cutting tool should be inserted into the collet before inserting it into the MAXIN chuck.
