The Dormer Pramet C822 Woodruff Cutter is a cobalt-based HSS‑E tool designed for precise keyway milling in steel and related alloys. Built for machinists and production environments, it combines durable construction with reliable engagement in DIN 850 standard applications.

• Diameter: 32.5 mm
• Width of cut: 10 mm
• Overall length: 71 mm
• Teeth: 12 teeth
• Shank: 12 mm combi shank with Weldon flat and thread
• Material: cobalt-based HSS‑E with bright finish
• Helix angle: 10°
• Rake angle: 10°
• DIN standard: compliant with DIN 850
• Applications: keyway milling in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys

This cutter’s 12-tooth geometry and 10° helix support efficient material removal while maintaining neat, accurate keyways across a range of metals. The Weldon flat combined with a threaded combi shank provides a secure, repeatable fit in compatible holders, reducing runout for consistent milling results. The cobalt-based HSS‑E construction enhances wear resistance and heat tolerance, helping tool life in demanding milling tasks without compromising finish quality.
