Sutton T385 M3 x 0.5 Straight Flute Tap Intermediate - HSS - Bright - ISO 529
Available
The Sutton T385 is a straight flute tap (intermediate chamfer) for metric coarse (M) threads, made from high speed steel (HSS) with a bright finish. This listing covers 29 sizes from M2 x 0.4 to M52 x 5.
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 intermediate chamfer (Form D, 3.5 to 5 threads on the lead), generally for through holes.
The thread tolerance is ISO 2 / 6H. The tap is built to ISO 529: short machine tap construction.
