Sutton T463 3/8 x 16 TPI Forming Tap Single Coolant Groove - HSSE - Bright - ISO 529
Available
The Sutton T463 is a forming (roll) tap with single coolant groove for BSW threads, made from premium grade high speed steel (HSSE) with a bright finish. This listing covers 6 sizes from 1/8 x 40 TPI to 3/8 x 16 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 thread tolerance is Z3 Medium. The tap is built to ISO 529: short machine tap construction.
