Sutton T201 M5 x 0.8 Spiral Flute Tap R45 VA DH - HSSE - TiCN - DIN 371
Out of stock
The Sutton T201 is a spiral flute tap (R45 spiral, VA DH designation) for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a TiCN coating. This listing covers 6 sizes from M3 x 0.5 to M10 x 1.5.
The 45° right-hand spiral flute suits blind holes in long chipping materials: the high helix angle curls the chips and transports them back out of the hole. The tap cuts on reversal, so the flutes have rake on both front and back faces. The chamfer is Form C (2.5 x P), generally for blind holes.
The thread tolerance is ISO 2 / 6H. The tap is built to DIN 371: reinforced shank with square drive.
