Sutton T122 M4 x 0.7 Spiral Point Tap W - HSSE - Plasma Nitride - DIN 371
Available
The Sutton T122 is a spiral point (gun) tap (W designation) for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a plasma nitride (Ni) finish. This listing covers 5 sizes from M4 x 0.7 to M10 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 W designation is for soft materials, with a very high rake angle and low thread relief for good chip flow. 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 371: reinforced shank with square drive.
