Dormer E239 HSS-E-PM Blue Ring Shark Spiral Flute Tap M20 Sprial Flute

Blue Shark taps are designed for high performance thread production in a wide range of stainless steels. On these E239 series taps, the back taper further facilitates chip evacuation, reducing chipping on the last threads of the taps and reducing the torque when the tap reverses.

• Special flute geometry prevents nest formation of swarf, reducing the risk of re-cutting swarf on reversal
• Super B coating is a low friction and self lubricating hard coating which prevents built-up-edge and provides very high wear resistance
• Back taper facilitates chip evacuation, reducing chipping on the last threads of the taps and also reducing torque when tap reverses
• 40 degree helix and specific rake designed for excellent performance when threading blind holes
• HSS-E-PM Premium Powder Metal substrate provides superior abrasion resistance and edge strength
