Sutton T249 M6 x 0.75 Spiral Flute Tap R45 VA DH - HSSE - Steam Oxide - DIN 374
Available
The Sutton T249 is a spiral flute tap (R45 spiral, VA DH designation) for metric fine (MF) threads, made from premium grade high speed steel (HSSE) with a blue steam-oxide finish. This listing covers 7 sizes from M6 x 0.75 to M14 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 374: reduced shank with square drive.
Where this product is used
- Use in stainless steels and high strength steels up to 1000 N/mm2.
- Blind holes.
- Suitable for synchronous tapping in machine operations.
