This short-series drill excels at producing clean slots and precise shoulders in a range of tough materials. The combination of a flat Weldon shank and a robust Alcrona Primax coating reduces friction, minimizes built-up edges, and extends tool life under demanding milling conditions. The 3-flute geometry provides a good balance between material removal and finish quality, making it well-suited for high-accuracy slotting and shoulder operations in both ferrous and non-ferrous workpieces.
