Heavy Duty Self-Reversing tapping attachment

Tapping AttachmentsTapmatic's 'Constant Speed' Tapping is based on one of the basic rules of machining, 'Never reduce rpm during a cut'. For instance, when blind hole tapping is performed by a rigid tapping system or by machine spindle reversal, rpm are reduced as the machine feed stop is approached and the tap begins to slow. You are changing speeds in the middle of the cut and that reduces tap life drastically.Tapmatic's self-reversing tapping attachment maintains 'Constant Speed' in blind holes as well as through holes. Tap life is increased with these additional advantages: Accurate thread depth /- 1/5 of a revolution at speeds up to 5,000rpm; Increased production by eliminating 2 machine reversals per tapped hole; No reversal related machine wear and tear; High rpm capability to utilise the latest 'Top Speed' tap designs and a 25% increase in tap life.
