AYSWJTiNSDHSS TiN Coated Straight Shank Drill TiNSDSold0pcsThe WJ HSS TiN Coated Straight Shank Drill TiNSD is the TiN-coated version of the basic SD, recognisable by its gold finish. The coating is the difference: TiN lowers friction and resists wear and heat, keeping the same HRC30 rating as SD while extending tool life and usable speed. For stainless steel, however, substrate beats coating - choose the cobalt STD (HRC40); for deeper holes use LSD or SSD; for lowest cost per piece go back to SD. The substrate is HSS with a TiN coating. Sizes cover diameter 1~13mm, flute length 18~114mm and overall length 40~152mm, in 136 variants. Made in Taiwan. What does the coating actually change? On the same HSS substrate it makes the flute face more wear-resistant and chip flow smoother - the gap shows most in dry or high-speed drilling. Can it drill stainless? The listed materials are carbon and alloy steel plus aluminium and copper; use STD for stainless. Typical applications: production drilling where tool-change intervals matter, high-speed drilling of general steel, and hole-making in moulds and jigs.
