Sutton T907 1 BA Straight Flute Tap Set - HSS - Bright - ISO 529
Available
The Sutton T907 is a three-piece straight flute tap set for BA threads, made from high speed steel (HSS) with a bright finish. This listing covers 10 sizes from 10 BA to 1 BA.
Each set contains three taps in the same thread size: a taper tap, an intermediate tap and a bottoming tap. 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 taper tap has a Form A chamfer (6 to 8 threads on the lead), for short through holes. The intermediate tap has a Form D chamfer (3.5 to 5 threads on the lead), generally for through holes. The bottoming tap has a Form E chamfer (1.5 to 2 threads on the lead), for blind holes with very short thread run-out.
The set is built to ISO 529.
