About this product
This Irwin 12mm HSS Cobalt drill bit is designed for heavy-duty drilling in stainless steel and other high alloys, suiting tasks such as M12 clearance holes, pilot holes and general fabrication work in demanding materials.
It is made from HSS steel with 5% Cobalt content, which improves red hardness and heat resistance, giving extended life compared with standard HSS bits. The 135° split point grinding centres the bit 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, while a golden tempered surface finish reflects the heat treatment process. Overall length is 151mm with a working length of 101mm, supplied as a single bit.
