A set of 19 high-speed steel cobalt drill bits with a bronze surface finish, stored in a durable metal case. Each bit is cylindrical with a ground, 135° cross-cut tip designed for precise drilling into a range of materials. The set covers sizes from 1 mm to 10 mm in 0.5 mm increments, and the bits are compatible with standard drill chucks for sizes 1–10 mm. Made from a cobalt alloy, they are suitable for drilling into steel, VA-steel, cast steel, non-ferrous metals, plastics, and special alloys, with a maximum tensile strength of 1100 N/mm². The bits are supplied in a metal storage case for organization and protection and feature a bronze finish for easy identification and durability.
