Engineered for precise corner radii in tight machining spaces, the Dormer Pramet C70 corner rounding cutter is designed for chamfer milling and edge finishing across a broad range of metals. Built for reliability, this extra-short series tool features a 25 mm Weldon shank and a cobalt-based HSS-E substrate with a bright finish, delivering consistent results in demanding setups.

• Shank: Weldon 25 mm shank for secure clamping and repeatable depth control in end mill holders.
• Cutting diameter and radius: 48 mm diameter with a 15 mm profile radius for precise corner rounding.
• Overall length: 105 mm total length, optimized for access in confined spaces.
• Flutes: 5-flute geometry that balances cutting efficiency with a smooth finish.
• Material and finish: Cobalt-based HSS-E with a bright finish for enhanced wear resistance and durability.
• Helix and rake angles: Specified helix and rake angles tailored for chamfer milling in multiple metals.
• Material versatility: Suitable for steel, stainless steel, cast steel, cast iron, wrought alloys, cast aluminium and copper/copper alloys, and high-temperature alloys.
• Standard: Produced to Dormer standards, ensuring compatibility with common toolholding systems.

This corner rounding cutter is ideal for shops that need precise 15 mm radius corners without multiple passes. The 5-flute, HSS-E composition provides a reliable balance between surface finish and material removal, while the Weldon shank ensures solid, slip-free performance in rigid setups. Its extra-short design minimizes overhang, improving rigidity in tight pockets and contributing to more accurate radii on every part.
