• Overall Length: 83 mm
• Reach with Neck Relief: 37.5 mm
• Shank: Weldon, 12 mm
• Material: Powder-metallurgical HSS-E with bright finish
• Flutes: 4-flute design
• Helix Angle: 30°
• Rake Angle: 12°
• Standard: DIN 844 K
• Applications: Shoulder milling, slot milling, ramping; suitable for free-machining and plain carbon steels, copper and copper alloys

The tool’s 4-flute geometry supports efficient material removal and smooth finishing, while the 30° helix promotes steady chip flow and reduced cutting forces during deep-pocket and shoulder work. The 12° rake angle further enhances chip control and surface quality, helping to minimize burr formation on finish passes. A robust 12 mm Weldon shank provides secure seating in collets and end-mill holders, preserving rigidity during higher-speed operations. With its DIN 844 K compatibility, this end mill fits standard milling setups and fixtures for quick, reliable replacements. Designed for use on free-machining and plain carbon steels as well as copper and copper alloys, it’s a versatile choice for mixed-material machining in a single tool.
