The set of 6 cobalt drill bits for metal and stainless steel from Alpen offers a high-quality solution for precise drilling work in tough and hard materials. The twist drills are made from HSS Cobalt, which increases their durability and resistance. With a reinforced core diameter, these drill bits are particularly suitable for stainless and acid-resistant chrome-nickel steels. The short design enables optimum handling, especially when used with hand drills. The set includes the most common diameters from 2 to 8 mm, which are supplied in a practical cassette with a triangular shank. This design ensures a secure hold in the drill chuck and makes handling easier.
