Designed for precision Woodruff keyway milling, the Dormer Pramet C822 Woodruff Cutter delivers reliable performance for machinists and fabrication shops working with steel and alloy components. This cobalt-based HSS-E cutter combines durability with clean, accurate cuts in standard keyways (DIN 850).

• Diameter: 10.5 mm
• Width of cut: 3.0 mm
• Overall length: 50 mm
• Teeth: 8 cutting edges for consistent material removal
• Material and finish: cobalt-based HSS-E with a bright finish for enhanced wear resistance
• Helix and rake: 10° helix and 10° rake angle to optimize cutting forces and chip formation
• DIN standard: conforms to DIN 850 Woodruff cutter sizing for interchangeability
• Shank: 6 mm combi shank with Weldon flat and thread for secure seating in toolholders
• Applications: ideal for keyway milling in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys

The C822 Woodruff Cutter is built to reduce chatter and produce clean, precise keyways, improving assembly fit and reducing rework. The cobalt-based HSS-E construction provides enhanced hardness and wear resistance, delivering longer tool life in demanding materials. The Weldon-flat combi shank ensures repeatable accuracy and secure clamping, while the 10° helix helps manage cutting forces for smoother operation in both CNC and manual milling setups. This makes it a dependable choice for maintenance, repair, and production environments where accurate keyways are critical.
