Irwin HSS Pro Tin Coated Drill Bits - 40 Piece Set

Irwin

Drill through metal and tough alloys with ease using Irwin HSS Pro TiN drill bits. Engineered for superior performance, these drill bits offer up to 40-60% increased speed and 10-20% increased feed compared to traditional HSS bits, without significantly compromising their lifespan. The Titanium Nitride (TiN) coating acts as a poor heat conductor, efficiently diverting heat into chips and coolant, thus prolonging drill bit life. Featuring a 135° split point grinding tip, they ensure perfect centring and require less drilling pressure. The high-quality HSS steel body with a 2.5µ TiN coating provides exceptional hardness (approx. 80 HRC) and wear resistance, while its low coefficient of friction minimizes power consumption and heat generation. Ideal for professional and DIY use in home improvement projects. Irwin HSS Pro Tin Coated Drill Bits, designed for metal drilling, durable TiN coating, high speed and feed rates, 135° split point, wear-resistant, low friction.
