Sutton T472 1/2 x 26 TPI Straight Flute Tap Taper - HSS - Bright - ISO 529
Available
The Sutton T472 is a straight flute tap (taper chamfer) for BSB threads, made from high speed steel (HSS) with a bright finish. This listing covers 4 sizes from 5/16 x 26 TPI to 1/2 x 26 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 529: short machine tap construction.
