Irwin Pro Titanium Nitride Coated Drill Bit

The Irwin IRW10502595 is an 8mm diameter HSS Pro TiN Coated Drill Bit measuring 8.0 x 117mm in size, supplied individually. This popular diameter is extensively used for M10 clearance holes and general heavy-duty metalworking applications, making it essential for engineers, fabricators, and maintenance professionals working with steel and harder alloys. The 8mm size offers excellent versatility for medium to heavy-duty drilling tasks, whilst the 117mm 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%. The 135° split point grinding tip delivers 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 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 demanding metalwork environments.
