The Dormer Pramet C70 20.0 mm x 10 mm HSS-E Flatted Shank Corner Rounding Cutter is a compact, four‑flute tool designed for precise corner radii and chamfer milling in tough metals. Built to deliver clean, repeatable results, it’s ideal for production environments that demand reliability and accuracy.

• Diameter: 20.0 mm
• Corner radius: 10 mm
• Shank: Flatted 20 mm Weldon shank for secure seating
• Material: Cobalt-based HSS‑E with bright finish for improved wear resistance
• Flutes: 4-flute geometry for balanced rigidity and smooth cutting action
• Length: Extra-short series designed to reduce vibration and improve rigid cutting
• Standard: Manufactured to DORMER standards for compatibility and reliable performance
• Applications: Suitable for corner rounding and chamfer milling in steel, stainless steel, cast iron, wrought alloys, cast aluminium and copper or copper alloys, and high-temperature alloys

This cutter provides a precise 10 mm corner radius with a robust HSS‑E construction, enabling clean transitions and tight corners even in challenging materials. The cobalt content enhances wear resistance for longer tool life, while the extra‑short geometry minimizes chatter and improves dimensional accuracy on demanding parts. Perfect for shops and production lines that prioritize repeatable radii, tight tolerances, and efficient setup.
