IRWIN HSS Pro TiN Coated Drill Bit 4.5mm x 80mm
High-speed steel drill bit with TiN coating for 40-60% faster drilling in metals. 135° split point for precision. 80mm length.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for superior performance in drilling metal and harder alloys. With a titanium nitride (TiN) coating, these bits allow for a 40-60% increase in drilling speed and a 10-20% boost in feed rate compared to standard HSS twist drill bits, all while maintaining longevity.
Key features include a 135° split point grinding tip that ensures precise centring and reduces drilling pressure. The TiN coating, known for its poor heat conduction, diverts heat into the chips and coolant, minimising heat transfer to the drill bit and enhancing durability.
Crafted from high-quality HSS steel, each bit is coated with 2.5µ Titanium Nitride (TiN), offering an impressive hardness of approximately 80 HRC and exceptional wear resistance. The low coefficient of friction reduces power consumption and heat generation during drilling, making it a reliable choice for demanding applications.
