This tool is engineered to handle slotting in a range of materials, including steel, cast iron, copper and their alloys, as well as titanium and its alloys. The Alcrona Primax coating minimizes built‑up edge and enhances wear resistance, while the powder‑metallurgical HSS substrate provides a tough, reliable cutting edge. The combination of a 30° helix and a 12° rake angle supports smooth chip formation and productive cutting in shallow slots, pockets, and shoulder geometry with reduced cutting forces. The Weldon 12 mm shank ensures solid clamping and minimal runout with standard toolholding, giving you consistent results across multiple setups.
