Sutton T667 1-1/8 x 7 TPI Spiral Flute Tap R15 H - PM-HSS Co - TiCN - DIN 2184-1
Available
The Sutton T667 is a spiral flute tap (R15 spiral, H designation) for UNC threads, made from powder metallurgy, 8% cobalt high speed steel (PM-HSS Co) with a TiCN coating. This listing covers 11 sizes from 1/4 x 20 TPI to 1-1/8 x 7 TPI.
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 H designation is for hard materials that form short chips, with a low rake angle and low thread relief. The chamfer is Form C (3 x P), generally for blind holes.
The thread tolerance is 2BX. The tap is built to DIN 2184-1.
