About this product
This Irwin HSS Pro drill bit is designed for drilling metal and tougher alloys, measuring 6.5mm diameter with an overall length of 101mm and a working length of 63mm, supplied as a single bit. The 6.5mm size suits precise engineering and fabrication work requiring tolerances between standard 6mm and 7mm sizes.
The bit is made from HSS steel with a 2.5µ Titanium Nitride coating of around 80 HRC hardness, giving good wear resistance and a low coefficient of friction. This allows drilling speeds to be increased by 40–60% and feed rates by 10–20% compared with standard HSS bits, without significantly reducing tool life, while reducing power consumption and heat build-up in the bit.
A 135° split point tip provides accurate centring and reduced drilling pressure, helping to prevent walking and produce clean, accurate holes.
