Irwin Pro Titanium Nitride Coated Drill Bit

The Irwin IRW10502600 is an 11mm diameter HSS Pro TiN Coated Drill Bit measuring 11.0 x 142mm in size, supplied as a single bit. This larger diameter is essential for heavy-duty metalworking applications, including structural steel fabrication, large clearance holes, and industrial maintenance work involving thicker metal sections and tougher alloys. The 11mm size combined with the extended 142mm overall length provides excellent depth capacity for demanding applications requiring substantial material removal. The Titanium Nitride coating delivers impressive performance improvements, with drilling speeds 40-60% faster than conventional HSS bits and feed rates boosted by 10-20%. The 135° split point tip delivers perfect centring from initial contact, eliminating walking and reducing drilling pressure for cleaner, more accurate holes. Constructed from premium HSS steel with a 2.5µ TiN coating offering 80 HRC hardness, the bit features outstanding wear resistance even under 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 applications.
