Sutton T390 M12 x 1.75 Straight Flute Tap Left Hand Intermediate - HSS - Bright - ISO 529
Out of stock
The Sutton T390 is a straight flute tap (intermediate chamfer, left hand) for metric coarse (M) threads, made from high speed steel (HSS) with a bright finish. This listing covers 11 sizes from M3 x 0.5 to M20 x 2.5.
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 LH. The tap is built to ISO 529: short machine tap construction.
