About this product
This 3.3mm HSS Cobalt drill bit from Irwin is designed for drilling stainless steel and other high alloy materials, suiting specialist metalworking and technical fabrication where precise clearance is needed. It has an overall length of 65mm and a working length of 36mm.
The bit is made from high quality HSS steel containing 5% Cobalt, which improves red hardness and heat resistance, giving extended life compared to standard HSS bits. A 135° split point grinding allows the bit to centre accurately without centre punching, reducing drilling pressure and preventing walking. The industrial quality ground flute aids accurate drilling and efficient chip removal, and the bit has a golden tempered surface finish.
