The Dormer Pramet C70 10.0 mm x 1 mm HSS-E Flatted Shank Corner Rounding Cutter is an extra-short, four-flute tool designed for precise corner radii and chamfer milling. Crafted for durability across common machining materials, it delivers reliable performance in tight-access applications.

• Diameter and radius: 10.0 mm cutting diameter with a 1 mm radius profile for clean, defined corners.
• Overall length: 60 mm, providing reach in confined pockets while maintaining rigidity.
• Flute count: 4-flute design optimized for efficient material removal and smooth finishing.
• Shank type: Flatted Weldon shank (10 mm) for secure seating and reduced slip in the holder.
• Material and finish: Cobalt-based HSS-E with a bright finish, offering extended wear resistance at higher temperatures.
• Cutting geometry: Optimized helix and rake angles tailored for chamfer milling and corner rounding in a variety of steels and alloys.
• Applications: Suitable for steel, cast steel, stainless steel, cast iron, wrought copper alloys, copper and copper alloys, and high-temperature alloys.
• Brand and standard: Manufactured to DORMER Pramet standards for consistent quality and interchangeability.

With its cobalt-enhanced HSS-E composition, the cutter maintains sharpness longer when milling tougher materials, while the flatted 10 mm Weldon shank provides a secure, vibration-resistant interface. The extra-short body and four flutes deliver precise radii with controlled chip evacuation, making it well-suited for finish passes on corners and edges in automation-friendly or high-precision work. This tool is ideal for shops performing tight-radius chamfers on brackets, housings, tooling components, or any workpiece requiring clean, reproducible corner radii. For best results, pair with appropriate coolant and steady feeds to maximize tool life and surface finish.
