IRWIN HSS Pro TiN Coated Drill Bit 12.0mm
High-speed IRWIN TiN-coated drill bit (12mm) for metal & tough alloys. 40-60% faster drilling with 135° split point.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for optimal performance when drilling metal and tough alloys. Featuring a Titanium Nitride (TiN) coating, it offers superior wear resistance and heat deflection, ensuring extended tool life and efficient drilling operations.
This drill bit increases speed by 40–60% and feed rates by 10–20% compared to standard HSS bits, without compromising durability. Its 135° split point tip ensures precise centring and reduced drilling pressure, minimising slippage and improving accuracy.
The low coefficient of friction from the TiN coating reduces power consumption and heat buildup, directing thermal load into the chips and coolant rather than the bit. Manufactured from high-speed steel (HSS) and coated with a 2.5µm TiN layer (approx. 80 HRC hardness), these bits excel in demanding applications.
