Sutton T180 G 1 x 11 TPI Spiral Point Tap - HSSE - TiN - DIN 5156
Available
The Sutton T180 is a spiral point (gun) tap (N designation) for BSPF (G) threads, made from premium grade high speed steel (HSSE) with a gold titanium nitride (TiN) coating. This listing covers 8 sizes from G 1/8 x 28 TPI to G 1 x 11 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 N designation is for normal, general purpose materials, with a normal rake angle and normal thread relief. The chamfer is Form B (4.5 x P), for through holes in medium and long chipping materials.
The thread standard is ISO 228. The tap is built to DIN 5156: reduced shank with square drive.
