About this product
This Irwin 3.0mm HSS Cobalt drill bit is designed for drilling stainless steel and other high alloys, suiting small to medium fixings, pilot holes and general fabrication work. The bit body is made from HSS steel with 5% Cobalt content, which improves red hardness and heat resistance, giving extended tool life when working demanding materials.
A 135° split point grinding provides accurate centring from first contact, reducing drilling pressure and preventing the bit from wandering. The industrial quality ground flute design supports precise drilling and efficient chip removal, helping to avoid binding during use.
The bit has a golden tempered surface finish resulting from its heat treatment. Overall length is 61mm, with a working length of 33mm.
