About this product
This Irwin HSS Pro drill bit is designed for drilling metal and tougher alloys, suiting tasks such as M8 bolt clearance holes, cable gland installation and general fabrication in steel. It measures 6.0mm diameter with an overall length of 93mm and a working length of 57mm, supplied individually.
The bit is made from high-quality HSS steel with a 2.5µ Titanium Nitride (TiN) coating, giving a hardness of around 80 HRC and strong resistance to wear. TiN's low coefficient of friction reduces power consumption and heat build-up, directing heat into the chips and coolant rather than the bit itself. Compared with traditional HSS twist drills, speed can be increased by 40-60% and feed rate by 10-20% without significantly reducing tool life.
A 135° split point grinding tip provides accurate centring from first contact, reducing drilling pressure and removing the need for centre punching.
