Irwin Pro Titanium Nitride Coated Drill Bit 3.5mm 70mm Pack of 1
The Irwin IRW10502580 is a 3.5mm diameter HSS Pro TiN Coated Drill Bit with an overall length of 70mm, supplied as a single bit. This compact size is ideal for precision drilling work in metal fabrication, electrical installations, and general metalworking where smaller pilot holes or fixing points are required. The 3.5mm diameter offers excellent control and accuracy for detailed work, whilst the Titanium Nitride coating delivers 40-60% faster drilling speeds compared to conventional HSS bits. The 135° split point tip ensures perfect centring from the first contact, eliminating walking and reducing the need for centre punching. Manufactured from high-quality HSS steel with a 2.5µ TiN coating (80 HRC hardness), this drill bit provides exceptional wear resistance and extended tool life. The coating's low friction properties divert heat into chips and coolant rather than the bit itself, maintaining cutting performance even during demanding applications. Features and Benefits: • 3.5mm x 70mm dimensions perfect for precision metalwork • TiN coating enables 40-60% speed increase over standard HSS • 135° split point for accurate hole positioning • Low friction coating reduces heat generation • Suitable for drilling harder, tougher alloys Specifications: Tip Diameter (mm): 3.5 Working Length (mm): 39 Overall Length (mm): 70 Pack Qty.: 1 Size: 3.5 x 70mm
