Irwin Pro Titanium Nitride Coated Drill Bit

The Irwin IRW10502576 is a 3mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 61mm, supplied individually. This popular smaller diameter is extensively used for light to medium-duty metalwork applications, including small fixings, electrical installations, precision engineering work, and general fabrication tasks where accurate hole sizing is required. The 3mm diameter offers excellent versatility for a wide range of drilling applications whilst maintaining good strength and durability. Enhanced with Titanium Nitride coating, this drill bit achieves 40-60% faster drilling speeds than traditional HSS bits, with feed rates improved by 10-20% without compromising tool lifespan. The 135° split point grinding tip ensures perfect centring from first contact, reducing drilling pressure and eliminating the need for centre punching in most applications. Manufactured from high-quality HSS steel with a 2.5µ TiN coating (80 HRC hardness), this drill bit provides exceptional wear resistance. The low friction properties of the coating reduce power consumption whilst diverting heat into chips and coolant, ensuring the drill bit maintains cutting performance throughout extended use in professional metalworking environments.
