The Dormer Pramet C70 corner rounding cutter is a compact, high-precision tool designed for chamfering and edge rounding in demanding metalwork. Built for machinists and engineers who need reliable, repeatable radii on a variety of metals, it delivers consistent results in tight spaces and hard materials.

• Tool type: Extra-short corner rounding cutter with a four-flute design for efficient chip removal and precise radii
• Diameter: 35 mm for robust cutting and strong edge engagement
• Overall length: 100 mm to reach into constrained work areas with stability
• Profile radius: 12.5 mm radius to produce clean, rounded corners
• Shank: 20 mm Weldon shank with a flatted section for secure seating in holders
• Material and finish: Cobalt-based HSS-E with a bright finish for wear resistance and long tool life
• Standard: Built to Dormer standard for reliable interchangeability and compatibility
• Cutting angles: Optimized helix and rake angles designed for efficient chamfer milling
• Applications: Effective on steel, cast steel, stainless steel, cast iron, wrought alloys, cast aluminum, copper and copper alloys, and high-temperature alloys

Designed to deliver durable performance across a range of materials, this cutter minimizes tool chatter and produces smooth, precise radii on edges. The cobalt-based HSS-E core resists wear during extended cuts, while the Weldon shank and flat section ensure a secure, repeatable fit in standard holders. Whether refining edges on structural components or finishing details on castings and alloys, this Dormer Pramet tool helps you achieve accurate corner rounding with fewer passes and consistent results.
