• Standard: DIN 327 D
• Series: Extra-short (short series)
• Applications: Copy milling and 3D contouring in free-machining steel and copper/copper alloys

This end mill is tailored for precise replication of complex surfaces and tight radii. The 2-flute design balances rigidity with efficient chip clearance, while the 30° helix and 12° rake optimize cutting action and reduce built-up edge on copper alloys. The 6 mm Weldon shank provides stable clamping, helping maintain accuracy during copying and finishing passes. With the cobalt-enriched HSS-E composition and a bright finish, you get durable edge retention and dependable performance across multiple jobs. Designed to DIN 327 D, this tool fits a wide range of compatible machines and setups, making it a reliable choice for detailed mold work, small-scale prototyping, and precise contouring tasks.
