Description
The Dormer Pramet C306 4.0mm HSS-E-Powder Metall Primax slot drill is a compact, high-precision tool designed for slot milling, shoulder milling, and ramping in free‑machining steels and copper alloys. Its extra-short design and robust Weldon shank make it ideal for tight pockets and intricate milling tasks.
- Diameter: 4.0 mm
- Length of Cut: 7 mm
- Overall Length: 51 mm
- Shank: 6 mm Weldon shank (Primax)
- Material/Grade: HSS‑E powder metallurgical with bright finish
- Flutes: 3
- Standard: DIN 327 D
- Helix/Rake: 30° helix, 12° rake angle
- Applications: Slot milling, shoulder milling, and ramping in free machining and plain carbon steel, as well as copper and copper alloys
This tool combines a 3‑flute geometry with powder‑metallurgical HSS‑E to deliver efficient chip evacuation and stable cutting in tight spaces. The 30° helix promotes smooth cutting and good surface finish, while the 12° rake angle enhances control during shoulder milling. The 6 mm Weldon shank provides secure clamping and minimizes runout, making it well suited for precision work in DIN 327 D compatible holders. The bright finish reduces built‑up edge and aids visibility during setup, helping to extend tool life in demanding materials.
