Looking for a reliable drill bit for demanding metal drilling? The IRWIN HSS drill bit with titanium nitride (TiN) coating, 6.5 mm diameter, is designed for fast, precise, and stable performance. The industry-grade ground flute efficiently removes chips and ensures clean holes without overheating the tool.
The TiN coating, with a hardness of approx. 80 HRC, is highly wear-resistant and, thanks to low friction, provides up to 6× longer life than standard HSS drill bits with black oxide. You can work with higher speeds (by 40–60%) and a faster feed (by 10–20%), while heat is transferred more to the workpiece and coolant than to the drill bit itself.
