The tool’s 3-flute geometry, combined with a 30° helix and neck relief, supports smooth chip evacuation and stable engagement in confined pockets. The Alcrona Primax coating enhances wear resistance and edge retention, contributing to longer tool life and more consistent finishes across production runs. A Weldon flat shank ensures secure seating in standard milling holders, reducing runout and improving repeatability. Designed for versatile metalworking tasks, this drill excels in high-precision slots and shoulders, delivering reliable performance from steel components to titanium assemblies.
