Irwin Pro Titanium Nitride Coated Drill Bit – 10502574

The Irwin IRW10502574 HSS Pro TiN Coated Drill Bits measure 2.0 x 49mm in size and are supplied as a pack of 2. This fine diameter is frequently used for small pilot holes, precision metalwork, electronics enclosures, and detailed fabrication projects where accurate hole placement and sizing are critical to project success. The 2mm diameter strikes an excellent balance between precision and versatility, whilst the twin-pack format provides cost-effective convenience for workshops and trade professionals. Enhanced with Titanium Nitride coating, these drill bits achieve 40-60% faster drilling speeds than traditional HSS bits, with feed rates improved by 10-20%. The 135° split point tip delivers perfect centring, essential for accurate drilling at this fine diameter without walking or premature bit wear. Manufactured from high-quality HSS steel with a 2.5µ TiN coating (80 HRC hardness), these drill bits provide 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—particularly important when working with harder alloys at smaller diameters.
