Shank-Tool Protector


In the Safe-Lock System, special drive keys in the chuck and grooves in the tool shank prevent the milling cutter from spinning during extreme machining or that it is pulled out of the chuck.

In addition to the frictional clamping forces of the particular clamping system, the tool is held using positive locking in the tool holder through the constructive design of the Safe-Lock System.

The combination of pull-out protection and best runout accuracy lead to a low vibration and as a result very efficient machining.

Due to the increased cutting depths and feeds, the metal removal rate can be increased by up to 100%, and to a similar degree tool wear decreases due to the excellent runout characteristics.
