Sutton T773 M8 x 1 Forming Tap Multi Coolant Groove - HSSE - TiCN - DIN 2174
Available
The Sutton T773 is a forming (roll) tap with multi coolant groove for metric fine (MF) threads, made from premium grade high speed steel (HSSE) with a TiCN coating. This listing covers 16 sizes from M5 x 0.5 to M20 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.
