Sutton T363 G 1/8 x 28 TPI Forming Tap Multi Coolant Groove - HSSE - TiCN - DIN 5156
Out of stock
The Sutton T363 is a forming (roll) tap with multi coolant groove for BSPF (G) threads, made from premium grade high speed steel (HSSE) with a TiCN coating. This listing covers 6 sizes from G 1/8 x 28 TPI to G 3/4 x 14 TPI.
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 ISO 228 X. The tap is built to DIN 5156: reduced shank with square drive.
