Irwin Pro Titanium Nitride Coated Drill Bit – 10502602

The Irwin IRW10502602 is a 13mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 151mm, supplied as a single bit. This is the largest diameter in the range, designed for the most demanding heavy-duty industrial applications, including major structural steelwork, large fixings, and fabrication tasks involving substantial metal sections and harder alloys. The 13mm diameter provides excellent capability for major drilling operations where substantial material removal is required. Combined with the 151mm overall length, this drill bit offers superior depth capacity for thick materials. The Titanium Nitride coating delivers exceptional performance with drilling speeds 40-60% faster than conventional HSS bits, whilst feed rates can be improved by 10-20%. The 135° split point tip provides perfect centring, eliminating walking and reducing drilling pressure. Constructed from premium HSS steel with a 2.5µ TiN coating offering 80 HRC hardness, the bit features outstanding wear resistance even under the most demanding industrial conditions. The low friction properties of the coating reduce power consumption whilst diverting heat into chips and coolant, ensuring the drill bit maintains cutting efficiency throughout extended use in professional metalworking environments.
