Sutton T695 5/8 x 11 TPI Spiral Flute Tap R50 VA PM - PM-HSSE V3 - TiCN - DIN 2184-1
Available
The Sutton T695 is a spiral flute tap (R50 spiral, VA PM designation) for UNC threads, made from powder metallurgy, vanadium grade high speed steel (PM-HSSE V3) with a TiCN coating. This listing covers 10 sizes from #2 x 56 TPI to 5/8 x 11 TPI.
The 50° right-hand spiral flute suits blind holes in long chipping materials: the high helix angle curls the chips and transports them back out of the hole. The tap cuts on reversal, so the flutes have rake on both front and back faces. The VA PM designation is for stainless and tough steels, with the VA geometry in powder metal high speed steel. The chamfer is Form C (2.5 x P), generally for blind holes.
The thread tolerance is 2BX. The tap is built to DIN 2184-1.
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 to 4 flutes, depending on size.
- 50° right-hand spiral flute.
- Form C chamfer, 2.5 x P.
- Thread tolerance 2BX.
- 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 2184-1 construction.
