IRWIN HSS Pro TiN Coated Drill Bit, 8.5mm x 117mm
High-speed steel drill bit with TiN coating for 40-60% faster drilling in metal and tough alloys. 8.5mm x 117mm size.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for optimal performance in drilling metal and tougher alloys. Featuring a high-speed steel (HSS) construction with a Titanium Nitride (TiN) coating, these drill bits offer superior durability and heat resistance. The TiN coating significantly enhances hardness (approximately 80 HRC) and reduces friction, leading to less heat generation and lower power consumption during drilling.
Improving upon traditional HSS drill bits, the IRWIN HSS Pro TiN allows for 40-60% higher drilling speeds and 10-20% increased feed rates without compromising longevity. The 135° split-point grinding tip ensures precise centring, minimising walking and reducing drilling pressure for cleaner, more accurate holes.
The TiN coating also acts as a thermal barrier, diverting heat into the chips and coolant rather than the tool itself, thereby prolonging bit life. Designed for professionals and serious DIYers, this drill bit delivers efficiency and reliability in high-demand applications.
