Irwin Pro Titanium Nitride Coated Drill Bit

The Irwin IRW10502572 HSS Pro TiN Coated Drill Bits measure 1.0 x 34mm in size and are supplied as a pack of 2. This smallest diameter in the range is ideal for precision drilling applications including pilot holes, small fixings in delicate metalwork, electronics enclosures, and intricate fabrication projects where accuracy is paramount. The compact 1mm diameter offers exceptional control for detailed work, whilst the twin-pack format provides excellent value and ensures a spare is always available for critical projects. Enhanced with Titanium Nitride coating, these drill bits achieve 40-60% faster drilling speeds than traditional HSS bits, with the coating's wear resistance particularly valuable given the delicate nature of this diameter. The 135° split point tip ensures perfect centring, crucial for preventing breakage in this fine size. 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 reduce power consumption and heat generation, critical factors when working with such a fine diameter where heat build-up can quickly compromise cutting performance.
