Nitro-Max taps are manufactured to DIN/ANSI specifications, with DIN lengths to allow for longer reach and deeper threading in a single pass. The ANSI shanks and squares are common to North American toolholding systems. TiCN (Titanium Carbo Nitride) coating helps to reduce galling, microwelding, seizing and adhesive wear. It allows for a smoother threading operation. TiCN helps to hold sharp edges and reduces the coefficient of friction. Manufactured from M35 Cobalt (HSS-E) with a high Vanadium content, these taps offer higher heat resistance and red hardness over conventional High Speed Steel taps. 1/4" - 20, nitro max spiral point tap
