In practical use, this drill supports stable cutting in long milling cycles with reduced chatter and a smooth pocket or slot finish. The Alcrona Primax coating enhances wear resistance and helps minimize built-up edge on tough metals, extending tool life across a range of alloys. The combination of neck relief and a generous reach maintains rigidity while allowing deeper slots and pockets, enabling efficient milling without frequent tool changes. Ideal for precise slotting and shoulder milling in steel, cast iron, copper alloys, and titanium alloys, it delivers predictable, high-quality results that align with professional machining workflows.
