Sutton T381 M14 x 2 Forming Tap Synchro - PM-HSSE V3 - TiN
Available
The Sutton T381 is a forming (roll) tap (synchro) for metric coarse (M) threads, made from powder metallurgy, vanadium grade high speed steel (PM-HSSE V3) with a gold titanium nitride (TiN) coating. This listing covers 13 sizes from M2 x 0.4 to M20 x 2.5.
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.
Where this product is used
- For aluminium and aluminium alloys.
- Blind holes up to 2 x d1.
Design features
- Powder metallurgy, vanadium grade high speed steel (PM-HSSE V3). The very fine and uniform grain structure allows high hardness while keeping good toughness, for materials up to 40 HRC and difficult-to-machine materials such as stainless steels.
- Gold titanium nitride (TiN) coating for 3 to 8 times longer tool life than uncoated tools, with higher speeds and feeds.
- Form C chamfer, 2.5 x P.
- Thread tolerance 6HX.
- For high speed and precision tapping.
- For rigid tapping in CNC machines with synchronised feed.
- Process of plastic deformation to imprint thread on material.
- h6 endmill shank.
