Sutton T158 M6 x 0.75 Spiral Point Tap VA - HSSE - Steam Oxide - DIN 374
Available
The Sutton T158 is a spiral point (gun) tap (VA designation) for metric fine (MF) threads, made from premium grade high speed steel (HSSE) with a blue steam-oxide finish. This listing covers 18 sizes from M6 x 0.75 to M20 x 1.5.
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 ISO 2 / 6H. The tap is built to DIN 374: reduced shank with square drive.
Where this product is used
