Sutton T671 M12 x 1.75 Straight Flute Tap GGG - Carbide VHM - TiCN - DIN 376
Available
The Sutton T671 is a straight flute tap (GGG designation) for metric coarse (M) threads, made from sub-micron grade solid carbide (VHM) with a TiCN coating. This listing covers 2 sizes from M12 x 1.75 to M16 x 2.
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 chamfer is Form C (2.5 x P), generally for blind holes.
The thread tolerance is 6H. The tap is built to DIN 376: reduced shank with square drive.
