Sutton T329 M3.5 x 0.6 Forming Tap Multi Coolant Groove Cu - HSSE - CrN - DIN 2174
Available
The Sutton T329 is a forming (roll) tap with multi coolant groove for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a chromium nitride (CrN) coating. This listing covers 7 sizes from M3 x 0.5 to M10 x 1.5.
A forming tap has no flutes and does not cut: it rolls the thread by displacing the metal, so it makes no chips and suits blind and through holes. Forming needs more machine power because of the torque involved, the rolled thread is stronger than a cut thread because the grain structure stays uniform through the thread form, and the tapping drill size differs from that of a cutting tap. The chamfer is Form C (2.5 x P).
The thread tolerance is 6HX. The tap is built to DIN 2174.
