Fein Annular Cutter Set M42, 2 In Cut D, 11 Pc 63134999027

11-Piece Cobalt Annular Cutter Set, 3/4" Weldon Shank This professional-grade 11-piece annular cutter set is engineered for high-performance drilling in hard-to-machine and inconsistent materials. Manufactured from premium M42 cobalt high-speed steel with a bright, uncoated finish, these cutters provide superior heat resistance and durability compared to standard HSS. The thin-wall design and specialized tooth geometry allow for aggressive, burr-free cutting, leaving a solid slug and requiring significantly less power than traditional twist drills. Equipped with a standard 3/4" Weldon shank (featuring two flats 90 degrees apart), this set is compatible with most major brands of magnetic drill presses and is ideal for heavy-duty industrial applications, including steel plate and structural metalwork.
