About this product
This is a 12.0mm HSS Pro TiN Coated drill bit from Irwin, supplied individually with an overall length of 151mm and a working length of 101mm. It is designed for drilling metal, including harder and tougher alloys, and suits heavy-duty tasks such as large clearance holes, structural metalwork and thicker steel sections.
The body is made from high-quality HSS steel with a 2.5µ Titanium Nitride coating of around 80 HRC hardness, giving good wear resistance. Compared with standard 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 the chips and coolant rather than the bit.
A 135° split point grinding tip provides accurate centring and reduces drilling pressure from first contact.
