Sutton T393 M3 x 0.5 Spiral Point Tap Intermediate - HSSE - Bright - ISO 529
Available
The Sutton T393 is a spiral point (gun) tap (intermediate chamfer) for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a bright finish. This listing covers 13 sizes from M2.5 x 0.45 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 tap has a intermediate chamfer (Form D, 3.5 to 5 threads on the lead), generally for through holes.
The thread tolerance is ISO 2 / 6H. The tap is built to ISO 529: short machine tap construction.
