The Dormer Pramet C247 8.0 mm HSS-E-Powder Metall End Mill is a compact, standard-length cutter designed for shoulder milling, slot milling, and ramping. Built for shops that demand reliable performance on free-machining steels and copper alloys, it combines a robust 4-flute design with powder-metallurgical HSS-E and a bright finish for lasting accuracy.

• Diameter: 8.0 mm
• Flutes: 4-flute configuration for efficient chip evacuation and rigidity
• Length of cut (LOC): 19 mm
• Overall length (OAL): 69 mm
• Shank: Weldon 10 mm for secure tool holding
• Material / Finish: Powder metallurgical HSS-E with bright finish
• Helix angle: 30° for smooth cutting action and good surface finish
• Rake angle: 12° to improve cutting clarity on shoulders
• Standard: DIN 844 K compatibility
• Applications: shoulder milling, slot milling and ramping in free machining and plain carbon steel and copper or copper alloys

The 4-flute design delivers steady cutting forces and efficient chip clearance, helping maintain dimensional accuracy even in longer pockets or deeper slots. Powder-metallurgical HSS-E provides high hardness and wear resistance, enabling higher cutting speeds and longer tool life on tougher materials while preserving a bright, consistent finish that reduces built-up edges. The 30° helix works with shoulder milling and ramping to produce cleaner entrances and exit paths, while the 12° rake angle supports efficient material shearing in copper alloys and carbon steels. With a Weldon 10 mm shank, it clamps securely in standard holders, delivering reliable repeatability across multiple passes.
