The Irwin IRW10502599 is a 10mm diameter HSS Pro TiN Coated Drill Bit measuring 10.0 x 133mm in size, supplied individually. This popular diameter is one of the most frequently used sizes for heavy-duty metalworking, ideal for M12 and M14 clearance holes, structural steel fabrication, and industrial maintenance applications involving steel and harder alloys. The 10mm size offers excellent versatility for demanding drilling tasks, whilst the substantial 133mm 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, with feed rates improved by 10-20% without compromising durability. The 135° split point grinding tip ensures perfect centring and reduced drilling pressure from initial 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 thermal properties ensure heat is diverted into chips and coolant rather than the bit itself, reducing power consumption and maintaining cutting performance throughout extended use in the most demanding metalwork environments.
