Sutton T176 3/4 x 16 TPI Spiral Point Tap VA - HSSE - Steam Oxide - DIN 2184-1
Available
The Sutton T176 is a spiral point (gun) tap (VA designation) for UNF threads, made from premium grade high speed steel (HSSE) with a blue steam-oxide finish. This listing covers 14 sizes from #4 x 48 TPI to 1 x 12 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. The VA designation is for stainless and tough steels, with a high rake angle and thread relief, so the chip flows continuously in an axial direction. The chamfer is Form B (4.5 x P), for through holes in medium and long chipping materials.
The thread tolerance is 2B. The tap is built to DIN 2184-1.
