Sutton T649 M18 x 2.5 Spiral Point Tap Left Hand - HSSE - Bright - DIN 376
Out of stock
The Sutton T649 is a spiral point (gun) tap (N designation, left hand) 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 gun (spiral point) nose curls the chip forward, ahead of the tap and out of the hole, so chip clogging is avoided and coolant can flow without problems. It suits through holes. The N designation is for normal, general purpose materials, with a normal rake angle and normal thread relief. The chamfer is Form B (4.5 x P), for through holes in medium and long chipping materials.
The thread tolerance is ISO 2 / 6H LH. The tap is built to DIN 376: reduced shank with square drive.
