Sutton T411 M8 x 1 Spiral Flute Tap Bottoming - HSSE - TiN - ISO 529
Available
The Sutton T411 is a spiral flute tap (R40 spiral, bottoming chamfer) for metric fine (MF) threads, made from premium grade high speed steel (HSSE) with a gold titanium nitride (TiN) coating. This listing covers 3 sizes from M8 x 1 to M12 x 1.5.
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 tap has a bottoming chamfer (Form E, 1.5 to 2 threads on the lead), for blind holes with very short thread run-out.
The thread tolerance is ISO 2 / 6H. The tap is built to ISO 529: short machine tap construction.
