Meet the Dormer Pramet C11 11.5 mm HSS-E powder-metallurgical slot drill—an extra-short, two-flute cutting solution engineered for shoulder milling, slotting, and ramping in free‑machining steels and copper alloys.

• Diameter: 11.5 mm
• Length of cut: 13 mm
• Overall length: 70 mm
• Shank: 12 mm Weldon shank for secure, repeatable clamping
• Material and finish: HSS‑E produced by powder metallurgy with a bright finish for consistent wear resistance
• Flutes: 2 flutes for efficient chip evacuation and stable cutting in slotting
• Standard: DIN 327 D compatible geometry
• Helix and rake: 30° helix and 12° rake angle to optimize cutting action for shoulder milling, slot milling, and ramping
• Applications: Suitable for free‑machining steel and copper or copper alloys

The tool’s short, rigid design enhances precision in tight workspaces, delivering clean slots and accurate shoulders with reduced deflection. The 30° helix provides smooth chip flow and steady cutting forces, while the 12° rake angle helps manage heat and minimize built‑up edge during shallow and deep ramps. With a 12 mm Weldon shank, it locks securely in fixtures and collets, promoting consistent runout control and dependable performance across multiple passes.
