Sutton T479 1-3/4 x 11 TPI Straight Flute Tap Pipe Taper - HSS - Bright - ISO 2284
Available
The Sutton T479 is a straight flute tap (taper chamfer) for BSPF (G) threads, made from high speed steel (HSS) with a bright finish. This listing covers 12 sizes from 1/8 x 28 TPI to 2 x 11 TPI.
Straight flutes suit through or blind holes, but they hold only a small amount of chips and do not transport them axially, so deep holes are best avoided except in short chipping materials. The tap has a taper chamfer (Form A, 6 to 8 threads on the lead), for short through holes.
The tap is built to ISO 2284.
