Sutton T689 M6 x 0.75 Spiral Point Tap Black Magic - PM-HSSE V3 - Hardlube - DIN 374
Available
The Sutton T689 is a spiral point (gun) tap (UNI designation, Black Magic range) for metric fine (MF) threads, made from powder metallurgy, vanadium grade high speed steel (PM-HSSE V3) with a Hardlube (TiAlN + WC/C) coating. This listing covers 17 sizes from M6 x 0.75 to M20 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 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 6HX. The tap is built to DIN 374: reduced shank with square drive.
Where this product is used
- Through holes.
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.
- 3 to 4 flutes, depending on size.
- Form B chamfer, 4.5 x P.
- Thread tolerance 6HX.
- The UNI designation is for normal, general purpose materials, with a normal rake angle and high thread relief, in powder metal high speed steel.
