Sutton T416 1-1/8 x 7 TPI Straight Flute Tap Bottoming - HSS - Bright - ISO 529
Available
The Sutton T416 is a straight flute tap (bottoming chamfer) for UNC threads, made from high speed steel (HSS) with a bright finish. This listing covers 23 sizes from #3 x 48 TPI to 1-1/2 x 6 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 bottoming chamfer (Form E, 1.5 to 2 threads on the lead), for blind holes with very short thread run-out.
The thread tolerance is 2B. The tap is built to ISO 529: short machine tap construction.
