• Length of cut: 53 mm
• Overall length: 110 mm
• Reach with neck relief: 64.5 mm
• Shank: Weldon 12 mm
• Material/Construction: HSS‑E powder metallurgy for increased toughness
• Coating: Alcrona Primax for wear resistance and extended tool life
• Helix angle: 35°
• Rake angle: 12°
• Design: HRA asymmetrical fine pitch profile
• Standard: DIN 844 L
• Applications: Shoulder milling and slot milling in plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high‑temperature alloys

This end mill is designed to maximize material removal while maintaining stability in deep pockets and shoulders. The combination of powder‑metallurgical HSS‑E and the Alcrona Primax coating enhances wear resistance under high cutting speeds and temperatures, helping to extend tool life and reduce downtime. The Weldon shank ensures a secure, repeatable clamping experience in standard holders, and the DIN 844 L compatibility guarantees broad machine compatibility. Ideal for shops requiring reliable roughing performance on a range of metals, from conventional steels to challenging high‑temperature alloys.
