Irwin

The Irwin IRW10502588 is a 5mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 86mm, supplied individually. This popular diameter is extensively used across metalworking trades for medium-duty drilling applications in steel, aluminium, and tougher alloys, making it a workshop essential. The 5mm size is ideal for M6 bolt clearance holes and general fabrication work where slightly larger apertures are required. Enhanced with Titanium Nitride coating, this drill bit achieves 40-60% faster drilling speeds than conventional HSS bits, significantly improving productivity whilst maintaining excellent durability. The 135° split point tip ensures precise centring and eliminates bit walking. Constructed from premium HSS steel with a 2.5µ TiN coating offering 80 HRC hardness, the bit delivers outstanding wear resistance. The coating's poor heat conductivity ensures thermal energy is diverted into chips and coolant rather than the drill bit, reducing power consumption and extending operational life in demanding metalwork applications. Features and Benefits: • 5mm x 86mm dimensions perfect for medium-duty metalwork • 40-60% faster drilling speeds with TiN coating • 135° split point provides accurate hole positioning • 80 HRC hardness coating for exceptional wear resistance • Reduced heat generation extends tool performance Specifications: Tip Diameter (mm): 5.0 Working Length (mm): 52 Overall Length (mm): 86 Pack Qty.: 1 Size: 5.0 x 86mm
