IRWIN HSS Pro TiN Coated Drill Bit, 8.0mm x 117mm
High-performance 8.0mm TiN-coated HSS drill bit for metal & alloys. 40-60% faster drilling with extended bit life.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for superior performance when drilling metal and harder alloys. Designed for professional use, this high-speed steel (HSS) drill bit features a Titanium Nitride (TiN) coating, enhancing durability and extending tool life. Compared to standard HSS drill bits, the TiN coating allows for 40-60% higher drilling speeds and 10-20% increased feed rates, all while maintaining optimal bit longevity.
The 135° split point grinding tip ensures precise centring and reduces drilling pressure, providing clean, accurate holes with minimal effort. The TiN coating is highly resistant to wear, with a hardness of approximately 80 HRC, while its low friction coefficient reduces power consumption and heat generation during drilling operations.
