Hoffmann Group 47 i&Eaniit' Tapping heads for machines with only one direction of rotation With built-in reversing gears for automatic return. After reaching the thread depth, the unit automatically reverses by raising the machine spindle (low-wear ball system ). Accelerated return (approx. factor 1.8xnm„). Length compensation by tension. With anti-rotation arm. Maintenance-free For cutting right- and left-hand threads. With quick-change system. Application: For automatic tapping on non-reversing machines with manual feed. For tapping through holes (with collets No. 335420 / 5430) and blind holes (with collets No. 335610 / 5620). Optional extras: For quick-change tapping collets see: No. 335420 / 5430 (without safety dutch) No. 335610 / 5620 (with safety clutch).

When set correctly, the safety clutch prevents tap breakage.. 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 Ml 8 - 42) on request.
