• Overall length: 61 mm
• Radius: 4.0 mm full profile radius
• Flutes: 2-flute ball-nose end mill
• Shank: Weldon 10 mm with flatted section
• Material & finish: HSS-E cobalt-based alloy with bright finish
• Helix angle: 30°
• Rake angle: 12°
• Standard: DIN 327 D
• Applications: Copy milling and contouring in free-machining steel and copper or copper alloys

Benefits from its design include enhanced rigidity and smooth surface finishes in complex 3D pockets thanks to the short, extra-sturdy geometry and the ball-nose profile. The cobalt-based HSS-E composition improves wear resistance for longer tool life when machining tougher materials, while the 10 mm Weldon shank provides secure, repeatable clamping for accurate, repeatable cuts. The 4 mm radius enables clean fillets and precise corner radii, making this end mill ideal for prototyping and production work that demands tight tolerances and reliable performance.
