Irwin Pro Titanium Nitride Coated Drill Bit 4.5mm 80mm Pack of 1
The Irwin IRW10502585 is a 4.5mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 80mm, supplied as a single bit. This intermediate size bridges the gap between 4mm and 5mm diameters, offering precise sizing for specialist fixings and applications requiring exact hole dimensions in metalwork. The 4.5mm diameter is particularly useful when working with specific bolt sizes or when exact tolerances are required for metal fabrication projects. The Titanium Nitride coating enables speed increases of 40-60% compared to standard HSS drill bits, whilst the 10-20% boost in feed rates improves productivity without compromising tool lifespan. Featuring a 135° split point grinding tip, this drill bit delivers perfect centring and reduced drilling pressure from initial contact. The high-quality HSS steel body with 2.5µ TiN coating (80 HRC hardness) provides exceptional wear resistance, whilst the low friction properties reduce power consumption and heat generation during operation. Features and Benefits: • 4.5mm x 80mm dimensions for precise metalworking applications • TiN coating delivers 40-60% speed improvement • 135° split point for accurate hole positioning • Low friction coating diverts heat into chips and coolant • Suitable for harder, tougher alloys Specifications: Tip Diameter (mm): 4.5 Working Length (mm): 47 Overall Length (mm): 80 Pack Qty.: 1 Size: 4.5 x 80mm
