## Description

The Irwin HSS Pro Titanium Nitride Coated Drill Bits are engineered for drilling metal and harder, tougher alloys with exceptional efficiency. Compared to traditional HSS twist drill bits, these advanced bits allow for speed increases of 40-60% and feed rates boosted by 10-20%, all without significantly reducing the drill bit's lifespan. The 2.5µ Titanium Nitride (TiN) coating provides outstanding wear resistance with a hardness of approximately 80 HRC, whilst its low coefficient of friction reduces power consumption and heat generation during operation. As TiN is a poor conductor of heat, the thermal energy produced during drilling is diverted into the chips and coolant rather than the drill bit itself, extending tool life and maintaining performance. Each drill bit features a 135° split point grinding tip that ensures perfect centring and reduced drilling pressure, delivering clean, accurate holes from the first contact. The drill bit body is manufactured from high-quality HSS steel, providing a robust foundation for the advanced TiN coating. Available in a comprehensive range of sizes to suit various metalworking applications. Features and Benefits: &bull; Titanium Nitride coating with 80 HRC hardness for exceptional wear resistance &bull; 40-60% faster drilling speeds compared to traditional HSS bits &bull; 135° split point tip for perfect centring and reduced pressure &bull; Low friction coating reduces heat and power consumption &bull; High-quality HSS steel construction for durability
