About this product
This Irwin HSS Pro TiN Coated Drill Bit is a 13.0mm diameter bit with an overall length of 151mm and a working length of 101mm, supplied as a single bit. It is intended for drilling metal and harder, tougher alloys, making it suitable for heavy-duty industrial applications such as structural steelwork and fabrication involving substantial material sections.
Compared with conventional HSS twist drills, speed can be increased by 40–60% and feed by 10–20% without significantly reducing tool life. The 135° split point tip aids centring and reduces drilling pressure, helping to prevent walking.
The bit body is made from HSS steel coated with 2.5 micron Titanium Nitride, giving a hardness of around 80 HRC and good wear resistance. TiN's low friction coefficient reduces power consumption and diverts heat into the chips and coolant rather than the bit itself.
