Irwin Pro Titanium Nitride Coated Drill Bit – 10502575

The Irwin IRW10502575 HSS Pro TiN Coated Drill Bits measure 2.5 x 57mm in size and are supplied as a pack of 2. This versatile diameter is commonly used for small fixings, precision metalwork, pilot holes for larger bits, and general light-duty applications across electrical installations, electronics work, and metal fabrication projects. The 2.5mm diameter offers excellent control and accuracy whilst providing sufficient strength for regular workshop use. The twin-pack format ensures excellent value and convenience for trade professionals. The Titanium Nitride coating delivers impressive performance with drilling speeds 40-60% faster than conventional HSS bits, whilst maintaining excellent tool life. The 135° split point grinding tip provides perfect centring from initial contact, reducing drilling pressure and eliminating walking. Constructed from premium HSS steel with a 2.5µ TiN coating offering 80 HRC hardness, these drill bits feature outstanding wear resistance. The coating's thermal properties ensure heat is diverted into chips and coolant rather than the bits themselves, reducing power consumption and maintaining cutting efficiency even when drilling harder, tougher alloys in demanding workshop environments.
