Irwin HSS Pro TiN-Coated Drill Bit 11 mm x 142 mm IRW10502600

The Irwin HSS Pro TiN Coated Drill Bit is designed for drilling metal and tougher alloys. It combines high-speed steel with a 2.5 µm Titanium Nitride coating to improve wear resistance and reduce friction. The bit features a 135° split point grinding tip for precise centering and lowered drilling pressure, enabling more controlled starts. relative to traditional HSS twist drill bits, it offers 40–60% faster drilling and 10–20% higher feed without a substantial reduction in lifespan. The TiN coating helps divert heat into the chips and coolant, contributing to cooler operation and extended edge life. The bit body is made from high-quality HSS steel and measures 11.0 mm in tip diameter and 142 mm in overall length, with a 94 mm working length.
