Irwin Pro Titanium Nitride Coated Drill Bit 12mm 151mm Pack of 1

The Irwin IRW10502601 is a 12mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 151mm, supplied individually. This substantial diameter is ideal for heavy-duty industrial applications, including large clearance holes for substantial fixings, structural metalwork, and demanding fabrication tasks involving thick steel sections and tougher alloys. The 12mm size offers excellent capability for major drilling operations, whilst the extended 151mm overall length provides superior depth capacity for thick materials and deep hole applications. Enhanced with Titanium Nitride coating, this drill bit achieves 40-60% faster drilling speeds than traditional HSS bits, significantly improving productivity in demanding environments. The 135° split point grinding tip ensures perfect centring and reduced drilling pressure from first contact. Manufactured from high-quality HSS steel with a 2.5µ TiN coating (80 HRC hardness), this drill bit provides exceptional wear resistance. The coating's poor heat conductivity ensures thermal energy is diverted into chips and coolant rather than the bit itself, reducing power consumption and maintaining cutting performance throughout extended use in the most challenging industrial metalwork applications.
