About this product
This Irwin HSS Cobalt drill bit is designed for drilling stainless steel and other high alloys, suiting demanding metalworking tasks such as pilot holes, clearance holes and heavy-duty fabrication. It is manufactured from HSS steel containing 5% Cobalt, which improves red hardness (heat resistance) and gives significantly extended life compared with standard HSS bits, along with a golden tempered surface finish.
The 135° split point grinding allows the bit to centre accurately from first contact, reducing drilling pressure and preventing bit walk without the need for centre punching. An industrial quality ground flute aids accurate drilling and efficient chip removal.
Diameter: 8.5mm. Working length: 75mm. Overall length: 117mm.
