Sutton T694 1/2 x 20 TPI Spiral Point Tap Black Magic - PM-HSSE V3 - Hardlube - DIN 2184-1
Available
The Sutton T694 is a spiral point (gun) tap (UNI designation, Black Magic range) for UNF threads, made from powder metallurgy, vanadium grade high speed steel (PM-HSSE V3) with a Hardlube (TiAlN + WC/C) coating. This listing covers 9 sizes from #4 x 48 TPI to 5/8 x 18 TPI.
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 UNI designation is for normal, general purpose materials, with a normal rake angle and high thread relief, 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 2BX. The tap is built to DIN 2184-1.
Where this product is used
- Universal high performance tapping.
- Use in stainless steels and high strength steels up to 850 N/mm2.
- Suitable for synchronous tapping in machine operations.
- Through holes up to 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.
- Hardlube (TiAlN + WC/C) coating for tapping hard-to-machine materials, with minimum quantity lubrication (MQL) or dry machining, longer tool life and higher cutting speeds.
- 2 to 4 flutes, depending on size.
- Form B chamfer, 4.5 x P.
- Thread tolerance 2BX.
- The UNI designation is for normal, general purpose materials, with a normal rake angle and high thread relief, in powder metal high speed steel.
