IRWIN HSS Pro TiN Coated Drill Bit, 6.5mm x 101mm
Premium IRWIN TiN-coated HSS drill bit (6.5mm) for metals and alloys. 135° split point, 40–60% faster drilling.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for precision drilling in metal and tough alloys. Featuring a premium high-speed steel (HSS) body with a 2.5μm Titanium Nitride (TiN) coating, these bits offer exceptional durability and heat resistance. The TiN coating, boasting an impressive hardness of ~80 HRC, minimises wear while reducing friction and heat generation during drilling.
Key Features:
- 135° split point tip ensures accurate centring and reduced drilling pressure, eliminating walking for cleaner starts.
- 40–60% faster drilling speeds and 10–20% increased feed rates compared to standard HSS bits, enhancing efficiency without sacrificing bit lifespan.
- Heat management: TiN’s poor thermal conductivity diverts heat into chips/coolant, preserving the bit’s cutting edge.
- Low friction: The coating reduces power consumption and heat buildup, ideal for prolonged use.
Ideal for professionals and hobbyists alike, this 6.5mm x 101mm drill bit (63mm working length) delivers superior performance in stainless steel, cast iron, and hardened alloys. A must-have for high-precision metalworking.
