IRWIN HSS Pro TiN Coated Drill Bit Set, 2.5mm x 57mm, 2-Pack
Premium TiN-coated HSS drill bits (2.5mm x 57mm) for metal/alloys. 40–60% faster drilling. Heat-resistant & durable.
The IRWIN HSS Pro TiN Coated Drill Bits are engineered for precision drilling in metal and tough alloys. These high-speed steel (HSS) drill bits feature a Titanium Nitride (TiN) coating, enhancing their durability and performance. The TiN coating provides a hardness of approximately 80 HRC, ensuring superior wear resistance and extended bit life.
- Increased Speed & Efficiency: Compared to traditional HSS bits, these allow 40–60% higher drilling speeds and 10–20% increased feed rates without compromising bit lifespan.
- Optimised Heat Dissipation: TiN’s poor conductivity directs heat into the chips and coolant, reducing wear on the drill bit.
- Precision Design: The 135° split point grinding tip ensures accurate centring and reduces drilling pressure for smoother operation.
- Reduced Friction: The TiN coating’s low coefficient of friction minimises power consumption and heat generation during drilling.
Ideal for professionals and DIY enthusiasts alike, these drill bits deliver long-lasting performance in demanding applications.
