The Dormer Pramet C70 corner rounding cutter is a compact, high-precision tool designed for chamfer milling and edge rounding. It combines a 24 mm cutting diameter with a 7 mm corner radius, mounted on a 16 mm Weldon shank for secure and reliable performance in diverse metalworking applications.

• Shank type: 16 mm Weldon shank with flatted surface for secure seating and positive drive
• Diameter: 24 mm
• Corner radius: 7 mm
• Overall length: 70 mm
• Flutes: 4-flute design for stable cutting action
• Material: Cobalt-based HSS-E with bright finish for enhanced wear resistance
• Standard: Dormer standard (DORMER) for reliable, consistent performance
• Helix and rake geometry: Optimized angles for chamfer milling in tough materials
• Applications: Chamfer milling and corner radii on steel, cast steel, stainless steel, cast iron, wrought aluminium, copper and copper alloys, and high-temperature alloys

This cutter is engineered to deliver precise, repeatable corner radii with minimal secondary finishing. The four-flute geometry supports efficient chip evacuation and smooth cutting in a range of demanding materials, while the cobalt-based HSS-E construction offers improved wear resistance and heat tolerance to extend tool life in everyday production scenarios.
