The safety clutch prevents tap breakage when set correctly. Blind hole threads can be tapped down to the bottom. The self-adjustment mechanism compensates for misalignment errors between the machine spindle and the component. The flexible length compensation is effective on compression and tension. It prevents the thread being cut incorrectly with manual or power feed. Application For tapping internal threads on reversible drilling machines, turret lathes. Applicable horizontally and vertically for right-handed threads. Supplied with 1 chuck key. Note Size 42 (= MT 5, for metric threads M18 - 42) on request.
