The Dormer Pramet C615 5/16" HSS Flatted Shank End Mill is a reliable regular-length cutting tool designed for shoulder milling, slot milling, and ramping in free machining steels and copper alloys. It’s built for everyday shop use where consistency and predictable results matter.
- Diameter: 5/16" (0.3125")
- Flutes: 4-flute geometry
- Length of cut: 3/4" (19.05 mm)
- Overall length: 2-1/2" (63.5 mm)
- Shank: 3/8" Weldon shank
- Material & finish: High-speed steel (HSS) with bright finish
- Helix angle: 30° for efficient chip evacuation
- Standard: ANSI standard
- Applications: Shoulder milling, slot milling, and ramping in free machining and plain carbon steel and copper or copper alloys
The 4-flute design provides a balance between material removal and finish, delivering steady cuts and predictable tool life in common machining scenarios. The HSS composition with a bright finish reduces built-up edge and helps maintain clean edges on slots and pockets. The 30° helix promotes smooth entry and reliable chip flow, aiding consistent performance during shoulder milling and ramping operations.
