Irwin Pro Titanium Nitride Coated Drill Bit

The Irwin IRW10502592 is a 6.5mm diameter HSS Pro TiN Coated Drill Bit measuring 6.5 x 101mm in size, supplied as a single bit. This intermediate diameter is particularly useful for specialist applications requiring precise hole sizing between standard 6mm and 7mm dimensions, commonly found in engineering and metal fabrication work. The 6.5mm size provides exact tolerances for specific fixings and components whilst the extended 101mm length offers improved reach and depth capacity. Enhanced with Titanium Nitride coating, this drill bit achieves 40-60% faster drilling speeds than conventional HSS bits, with feed rates improved by 10-20%. The 135° split point tip delivers perfect centring and reduced drilling pressure, ensuring clean, accurate holes from first contact. Constructed from premium HSS steel with a 2.5µ TiN coating offering 80 HRC hardness, the bit features outstanding wear resistance. The coating's thermal properties ensure heat is diverted into chips and coolant rather than the bit itself, reducing power consumption and maintaining cutting performance in harder alloys.
