Designed for durability and consistency, this tool combines the wear resistance of powder‑metallurgical HSS‑E with a bright finish that reduces built‑up edge and improves chip evacuation. The 30° helix promotes efficient cutting action in through‑slots and shallow grooves, while the 12° rake angle supports clean walls and precise dimensions in free machining metals. Ideal for shops seeking reliable, single‑tool versatility in compact milling operations where slotting and shoulder milling converge.
