The tool’s 4-flute geometry and 30° helix deliver steady chip flow and efficient material removal, making it well-suited for shallow to moderate-depth milling passes in free-machining steels and copper alloys. Powder-metallurgical HSS‑E combines wear resistance with toughness, helping extend tool life under tough milling conditions. The neck relief and long reach provide clearance for deep pockets and complex shoulder features without compromising rigidity. A 16 mm Weldon shank supports secure clamping and reduces runout for precise, consistent cuts. With its DIN 844 K standard and robust construction, this end mill is a reliable choice for shops performing pocketing, slotting, and ramping operations on common engineering materials.
