About this product
This Irwin HSS Pro drill bit is designed for drilling metal, including harder and tougher alloys, in workshop and industrial settings. It measures 7.0mm in diameter with an overall length of 109mm and a working length of 69mm, supplied individually.
The bit is manufactured from HSS steel with a 2.5µ Titanium Nitride (TiN) coating of around 80 HRC hardness, giving good resistance to wear. TiN is a poor conductor of heat, so heat generated while drilling is diverted into the chips and coolant rather than the bit itself, and its low coefficient of friction reduces power consumption.
A 135° split point grinding tip ensures accurate centring and reduces drilling pressure. Compared with traditional HSS bits, speed can be increased by 40-60% and feed rate by 10-20%, without a significant reduction in tool life.
