Sutton T670 M8 x 1.25 Straight Flute Tap GGG - Carbide VHM - TiCN - DIN 371
Available
The Sutton T670 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 3 sizes from M6 x 1 to M10 x 1.5.
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 chamfer is Form C (2.5 x P), generally for blind holes.
The thread tolerance is 6H. The tap is built to DIN 371: reinforced shank with square drive.
