• Length of Cut: 16 mm
• Overall Length: 66 mm
• Shank: Weldon shank, 10 mm diameter
• Material: Powder metallurgical HSS-E with a bright finish
• Helix Angle: 30° for efficient chip evacuation
• Rake Angle: 12° to improve cutting action and finish
• DIN Standard: DIN 844 K compliant
• Flatted Shank: Flatted section for secure grip in collets and holders
• Applications: Shoulder milling, slot milling, and ramping
• Compatible Materials: Free machining and plain carbon steel, copper and copper alloys

Benefits: This end mill delivers consistent, clean edges and reliable performance across a range of milling operations. The powder-metallurgical HSS-E substrate combines hardness and toughness for longer tool life, while the bright finish helps resist built-up edges. The 30° helix and 12° rake angle optimize chip control and cutting action, making it well-suited for pocket walls, grooves, and entry ramps in steel and copper-based materials. With a robust 10 mm Weldon shank and a flatted section, you get stable clamping and repeatable results in busy workshops and production environments.
