Meet the Dormer Pramet C139 2.0 mm slot drill—a compact, high-precision tool designed for slotting, shoulder milling, and ramping. Built for machinists and job shops working with free‑machining steels, plain carbon and alloy steels, cast iron, copper/copper alloys, and titanium/titanium alloys, it delivers clean slots and dependable performance in tight‑access applications.

• Diameter: 2.0 mm
• Length of Cut: 7 mm
• Overall Length: 51 mm
• Shank: 6 mm Weldon shank with a flat to prevent rotation
• Flutes: 2 flutes
• Material: HSS‑E (powder metallurgical) for improved edge strength
• Coating: TiCN coating for enhanced wear resistance
• Helix / Rake: 30° helix with 12° rake angle for efficient cutting
• DIN Standard: DIN 844 K compatibility
• Applications: Ideal for slot milling, shoulder milling, and ramping in constrained geometries

This 2‑flute slot drill is engineered to produce precise slots with consistent chip evacuation, even in challenging materials. The TiCN coating reduces wear, supporting longer tool life in abrasive alloys, while the powder‑metallurgical HSS‑E core provides a tough, reliable cutting action. The flatted Weldon shank adds anti‑rotation stability, helping minimize runout and chatter in high‑feed operations. With its compact form and specific geometry, it’s well suited for shallow pockets and tight slots where other drills struggle. Whether you’re updating an existing setup or tackling a demanding batch of parts, this tool helps you achieve clean slots, accurate depths, and repeatable results.
