About this product
This Irwin HSS Pro drill bit is designed for drilling metal and tougher alloys, suiting engineers, fabricators and maintenance work. It measures 8.0mm diameter with a 117mm overall length and 75mm working length, supplied individually.
The bit is made from high-quality HSS steel coated with 2.5µ Titanium Nitride (TiN), giving a hardness of around 80 HRC and strong resistance to wear. Compared with traditional HSS bits, speed can be increased by 40-60% and feed by 10-20% without significantly reducing tool life, as TiN's low friction and poor heat conductivity divert heat into chips and coolant rather than the bit.
It features a 135° split point grinding tip for accurate centring and reduced drilling pressure from first contact, making it suited to heavy-duty metalworking and deep hole drilling in steel and harder alloys.
