Sutton T357 M6 x 1 Straight Flute Tap DC IK - PM-HSS Co - TiCN - DIN 371
Available
The Sutton T357 is a straight flute tap (DC designation, internal coolant) for metric coarse (M) threads, made from powder metallurgy, 8% cobalt high speed steel (PM-HSS Co) with a TiCN coating. This listing covers 2 sizes from M6 x 1 to M8 x 1.25.
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 E (1.5 x P), for blind holes with very short thread run-out.
The thread tolerance is 6HX. The tap is built to DIN 371: reinforced shank with square drive. The internal coolant duct (IK) delivers coolant through the tap to the cutting zone.
