Sutton T400 M3 x 0.5 Forming Tap Single Coolant Groove - HSSE - TiN - ISO 529
Available
The Sutton T400 is a forming (roll) tap with single coolant groove for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a gold titanium nitride (TiN) coating. This listing covers 4 sizes from M3 x 0.5 to M6 x 1.
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 GH4 / 6H. The tap is built to ISO 529: short machine tap construction.
Where this product is used
- For cold forming of threads in materials with good flow characteristics.
- Through or blind holes.
- Depths up to approx. 1.5 x d1.
