Sutton T164 9/16 x 12 TPI Spiral Point Tap - HSSE - Bright - DIN 2184-1
Available
The Sutton T164 is a spiral point (gun) tap (N designation) for UNC threads, made from premium grade high speed steel (HSSE) with a bright finish. This listing covers 18 sizes from #2 x 56 TPI to 1 x 8 TPI.
The gun (spiral point) nose curls the chip forward, ahead of the tap and out of the hole, so chip clogging is avoided and coolant can flow without problems. It suits through holes.
