Dormer Pramet C822 10.5mm x 3.mm HSS-E Screwed Shank Woodruff Cutter DIN 850

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.
