Sutton T157 M6 x 0.75 Spiral Point Tap - HSSE - TiN - DIN 374
Available
The Sutton T157 is a spiral point (gun) tap (N designation) for metric fine (MF) threads, made from premium grade high speed steel (HSSE) with a gold titanium nitride (TiN) coating. This listing covers 14 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 N designation is for normal, general purpose materials, with a normal rake angle and normal thread relief. 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.
