Introducing the Dormer Pramet C70 corner rounding cutter—a compact, four-flute tool designed for precise chamfer milling across a broad range of metals. Built for professional machining, it delivers consistent 1.5 mm corner radii with a robust Weldon 10 mm shank.

• Diameter: 10.0 mm
• Corner radius: 1.5 mm profile radius
• Flutes: 4
• Overall length: 60 mm
• Shank: Weldon, 10 mm
• Material: HSS‑E cobalt-based steel with bright finish
• Series: Extra-short corner rounding cutter for rigid, precise milling
• Applications: Chamfer milling and edge rounding in steel, stainless steel, cast iron, wrought aluminum, copper and copper alloys, and high‑temperature alloys

The C70’s cobalt-based HSS‑E composition offers improved hardness and wear resistance, enabling reliable tool life even in tougher alloys. Its optimized helix and rake geometry promotes efficient material removal and smooth cutting action, reducing chatter in tight pockets and thin walls. The result is clean, repeatable corner radii that help parts mate precisely and finish confidently.
