Dormer Pramet C353 6.0mm HSS-E-Powder Metal Alcrona Primax Flatted Shank 3 Flute Short Series Slot Drill DIN 327 D

The Dormer Pramet C353 6.0 mm HSS‑E powder metallurgy with Alcrona Primax coating, flatted 6 mm Weldon shank, 3-flute short series slot drill (DIN 327 D), is engineered for precise slot milling, shoulder milling, and ramping in demanding metalwork. Built for reliability in tight cavities, it delivers consistent cuts across a range of metals including steels, cast iron, copper alloys, and titanium alloys.

• Diameter: 6.0 mm
• Length of cut: 8 mm
• Overall length: 52 mm
• Shank: 6 mm Weldon shank with a flatted profile (DIN 327 D)
• Flutes: 3
• Material: HSS‑E powder metallurgy core
• Coating: Alcrona Primax for wear resistance and smoother cutting
• Helix: 30° for efficient chip evacuation
• Rake angle: 12° to enhance cutting action
• Series: Extra short / short series design for rigidity in confined spaces
• Applications: slot milling, shoulder milling, and ramping
• Compatible materials: steel, cast steel, cast iron, copper or copper alloys, titanium or titanium alloys

Designed to perform in tight work envelopes, the combination of a short overall length and a flatted Weldon shank minimizes deflection and slip under load, delivering repeatable accuracy in every pass. The 3‑flute geometry promotes robust chip removal and stable cutting in medium to high‑strength alloys, while the Alcrona Primax coating reduces wear and helps extend tool life in challenging materials. This drill is well-suited for production environments and precision prototypes where clean slots and precise shoulders are essential, enabling smoother ramping into the workpiece and more consistent surface finishes.
