Sutton T116 M1.6 x 0.35 Spiral Point Tap VA PM - PM-HSSE V3 - TiCN - DIN 371
Available
The Sutton T116 is a spiral point (gun) tap (VA PM designation) for metric coarse (M) threads, made from powder metallurgy, vanadium grade high speed steel (PM-HSSE V3) with a TiCN coating. This listing covers 10 sizes from M1.6 x 0.35 to M10 x 1.5.
The gun (spiral point) nose curls the chip forward, ahead of the tap and out of the hole, so chip clogging is avoided and coolant can flow without problems. It suits through holes. The VA PM designation is for stainless and tough steels, with the VA geometry in powder metal high speed steel. The chamfer is Form B (4.5 x P), for through holes in medium and long chipping materials.
The thread tolerance is 6HX. The tap is built to DIN 371: reinforced shank with square drive.
Where this product is used
- Use in stainless steels and high strength steels up to 1000 N/mm2.
- Through holes.
- Suitable for synchronous tapping in machine operations.
- Depths up to approx. 3 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.
- TiCN coating for abrasive materials such as cast iron and aluminium alloys, and adhesive materials such as copper and copper-based alloys.
- 3 flutes.
- Form B chamfer, 4.5 x P.
- Thread tolerance 6HX.
- The VA PM designation is for stainless and tough steels, with the VA geometry in powder metal high speed steel.
- PM-HSSE V3 offers higher edge hardness than standard VA series.
- DIN 371 construction, reinforced shank with square drive.
