Sutton T192 M12 x 1.75 Spiral Flute Tap R40 - HSSE - Bright - DIN 376

The Sutton T192 is a spiral flute tap (R40 spiral, N designation) for metric coarse (M) threads, made from premium grade high speed steel (HSSE) with a bright finish. This listing covers 5 sizes from M12 x 1.75 to M20 x 2.5.

The 40° 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 N designation is for normal, general purpose materials, with a normal rake angle and normal thread relief. 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 376: reduced shank with square drive.
