It consists of deep grinding (processing) of the raw material, which translates into significantly extended drill bit life and improved performance . The product conforms to DIN 338 (parallel shank helical drills, jobber series) and ISO 235 (parallel shank and stub series drills and Morse taper shank drills).The products are made with added cobalt (8%), which further increases their durability and strength. Cobalt drills are designed for drilling in hard steel alloys, they also feature higher mechanical and thermal resistance.
