Sutton T127 M12 x 1.75 Spiral Point Tap Cu - HSSE - CrN - DIN 376
Available
The Sutton T127 is a spiral point (gun) tap (Cu designation) for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a chromium nitride (CrN) coating. This listing covers 3 sizes from M12 x 1.75 to M20 x 2.5.
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 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 376: reduced shank with square drive.
