Dormer Pramet C822 13.5mm x 4.mm HSS-E Screwed Shank Woodruff Cutter DIN 850

The Dormer Pramet C822 Woodruff Cutter is a precision HSS-E milling tool designed for reliable keyway milling across steel, stainless steel, cast iron, non‑ferrous metals, and high‑temperature alloys. Built for machinists and workshops, it combines robust construction with a practical combi shank for quick, secure mounting.

• Diameter × width of cut: 13.5 mm diameter with 4 mm width of cut; 56 mm overall length
• Teeth: 8 teeth for efficient material removal and smooth engagement
• Material and finish: cobalt-based HSS‑E with a bright finish for improved wear resistance
• Shank: 10 mm combi shank with Weldon flat and thread for secure seating and easy tool changes
• DIN standard: complies with DIN 850 standard
• Helix and rake: 10° helix and 10° rake angle to balance cutting action and chip control
• Applications: ideal for keyway milling in steel, stainless steel, cast steel, cast iron, non‑ferrous metals, and high‑temperature alloys

With its 8‑tooth geometry and cobalt‑based HSS‑E core, the C822 delivers dependable performance even in tough materials. The tool’s geometry supports clean, precise keyways and reduces feed‑rate limitations by promoting efficient chip evacuation. The Weldon flat with threaded shank ensures a secure, repeatable mounting on compatible milling centers, minimizing setup time and vibration. This makes the Dormer Pramet C822 Woodruff Cutter a solid choice for production runs, repairs, and refurbishment work where accurate keyways are essential.
