Ideal for tight-pocket machining and shallow-slot work, this drill excels at producing precise slots and clean shoulders with minimal deflection. The combination of a 30° helix and a 12° rake promotes efficient chip evacuation and smooth entry, while the Alcrona Primax coating reduces wear under demanding cutting conditions. The 10 mm Weldon shank ensures reliable clamping in standard toolholders, making setup quick and repeatable. Whether you’re profiling, deburring, or preparing slots for inserts, this tool delivers consistent results across a range of metallic materials.
