About this product
These Irwin HSS Pro TiN Coated Drill Bits are designed for drilling metal and harder, tougher alloys, supplied as a pack of two measuring 2.5 x 57mm (working length 30mm). The 2.5mm diameter suits small fixings, precision metalwork, pilot holes and general light-duty drilling in electrical, electronics and fabrication work. Manufactured from HSS steel with a 2.5µ Titanium Nitride coating of around 80 HRC hardness, the bits offer strong wear resistance. TiN is a poor conductor of heat, diverting heat into chips and coolant rather than the bit, and its low friction reduces power consumption. This allows drilling speeds 40-60% faster than standard HSS bits without significantly reducing tool life. A 135° split point grinding tip ensures accurate centring from first contact, reducing drilling pressure and preventing the bit from wandering.
