Pro Titanium Nitride Coated Drill Bit 7.5mm 109mm Pack 1

The Irwin IRW10502594 is a 7.5mm diameter HSS Pro TiN Coated Drill Bit measuring 7.5 x 109mm in size, supplied as a single bit. This intermediate diameter fills the gap between 7mm and 8mm sizes, offering precise hole dimensions for specialist fixings and engineering applications where exact tolerances are critical in metalwork. The 7.5mm diameter is particularly valuable for specific bolt clearances and custom fabrication projects requiring accurate sizing. The Titanium Nitride coating delivers exceptional performance with 40-60% faster drilling speeds compared to conventional HSS bits, whilst maintaining excellent tool life. The 135° split point tip provides perfect centring from initial contact, eliminating bit 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. The low friction properties of the coating reduce power consumption whilst diverting heat into chips and coolant, ensuring the drill bit maintains cutting performance even when working with harder, tougher alloys.
