The Dormer Pramet C11 1.0 mm slot drill is a compact micro-tool designed for precise shoulder and slot milling in tight spaces. Built for machinists working with free‑machining steel and copper alloys, it delivers reliable, consistent cuts in micro‑slots and fine features.

• Diameter: 1.0 mm
• Length of cut: 2.5 mm
• Overall length: 47 mm
• Shank: 6 mm Weldon shank for secure clamping and compatibility with standard holders
• Material: HSS‑E with powder metallurgical construction for improved hardness and wear resistance
• Finish: Bright finish for clear geometry and easier inspection
• Helix angle: 30° to promote smooth chip formation and steady cutting action
• Rake angle: 12° to aid cutting in shoulder milling and ramping applications
• Standard: DIN 327 D conforming geometry for reliable interchangeability
• Design: 2-flute, extra-short series optimized for rigidity and precision in micro‑slot work
• Applications: Shoulder milling, slot milling, and ramping in free‑machining steel and copper or copper alloys

This micro‑drill is engineered to minimize deflection in small slots while delivering clean, accurate finishes. The combination of powder‑metallurgy HSS‑E and a robust Weldon shank supports dependable tool life in repetitive productions and intricate prototyping alike. Ideal for creating tight slots, precise shoulders, and controlled ramping paths in delicate workpieces.
