Sutton T216 M14 x 2 Spiral Flute Tap R15 Ti - PM-HSS Co - TiCN - DIN 376
Available
The Sutton T216 is a spiral flute tap (R15 spiral, Ti designation) for metric coarse (M) threads, made from powder metallurgy, 8% cobalt high speed steel (PM-HSS Co) with a TiCN coating. This listing covers 5 sizes from M12 x 1.75 to M20 x 2.5.
The 15° right-hand spiral flute suits blind holes in tough, short chipping materials, up to 1.5 x D in depth. The slow helix does not transport chips well, so it has no advantage in soft or long chipping materials, especially deeper than 1.5 x d1. The chamfer is Form C (3 x P), generally for blind holes.
The thread tolerance is 6HX. The tap is built to DIN 376: reduced shank with square drive.
Where this product is used
- For Titanium based alloys.
- Blind holes up to approx. 1.5 x d1.
Design features
- Powder metallurgy, 8% cobalt high speed steel (PM-HSS Co). The cobalt keeps strength and hardness at very high cutting temperatures, which suits heavy duty tapping of materials up to 45 HRC.
- 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.
- 15° right-hand spiral flute.
- Form C chamfer, 3 x P.
- Thread tolerance 6HX.
- Unique cutting geometry for highly efficient swarf ejection.
- Optimised micro-finish for optimal process reliability and excellent thread quality.
- DIN 376 construction, reduced shank with square drive.
