The IRWIN HSS Pro TiN Coated Drill Bit is engineered for superior performance when drilling metal and tougher alloys. Its advanced Titanium Nitride (TiN) coating enhances durability and efficiency, allowing for 40–60% faster speeds and 10–20% increased feed rates compared to standard HSS drill bits, without compromising lifespan.
A key feature is the 135° split point tip, ensuring precise centring and reduced drilling pressure for smoother operation. The TiN coating (2.5µm thickness, ~80 HRC hardness) minimises friction, reducing heat build-up and power consumption while maximising wear resistance. Heat dissipation is optimised, as TiN redirects thermal energy into chips and coolant rather than the bit itself.
Ideal for professionals and DIY enthusiasts, this bit is crafted from high-quality HSS steel for reliability in demanding applications. Its 9.5mm diameter and 125mm overall length (81mm working length) make it versatile for various drilling tasks.
Key Benefits:
- TiN coating extends bit life and improves performance.
