Irwin Pro Titanium Nitride Coated Drill Bit – 10502591

The Irwin IRW10502591 is a 6mm diameter HSS Pro TiN Coated Drill Bit measuring 6.0 x 93mm in size, supplied individually. This versatile diameter is one of the most frequently used sizes for metalworking applications, ideal for M8 bolt clearance holes, cable gland installations, and general fabrication work in steel and harder alloys. The 6mm diameter offers excellent versatility for both light and medium-duty drilling tasks. The Titanium Nitride coating delivers impressive speed increases of 40-60% compared to traditional HSS drill bits, whilst feed rates can be boosted by 10-20% without compromising the bit's lifespan. The 135° split point grinding tip ensures perfect centring from initial contact, reducing drilling pressure and eliminating the need for centre punching. 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, maintaining cutting performance throughout extended use.
