The Dormer Pramet C822 Woodruff Cutter is a precision tool engineered for reliable keyway milling across steel, stainless steel, cast iron, and non-ferrous alloys. Designed to DIN 850 specs, it delivers consistent slots with a robust cobalt-based HSS-E composition and a screwed shank for secure, accurate performance.

• Woodruff cutter geometry: 6-tooth design optimized for smooth, balanced cutting and clean keyway slots.
• Cutting size: Diameter 7.5 mm with a 1.5 mm width of cut, suitable for precise keyway milling.
• Overall length: 50 mm, providing adequate reach for a variety of setups and workpiece thicknesses.
• Shank and mounting: 6 mm combi shank with Weldon flat and threaded portion for secure seating and reliable torque transmission.
• Material and finish: Cobalt-based HSS-E with a bright finish for enhanced wear resistance and hot-work performance.
• Helix and rake: 10° helix and 10° rake angle to improve chip evacuation and surface finish on hard metals.
• Standards: DIN 850 compliant, ensuring compatibility with standard holders and machines.
• Material compatibility: Effective for keyways in steel, cast steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys.

This tool is built for professionals who need dependable accuracy in keyway production and repair tasks. The 6-tooth configuration, combined with cobalt-based HSS-E and a Weldon-flat shank, delivers stable cutting, precise slot dimensions, and long tool life even in challenging materials. The bright finish reduces wear and buildup, while the 10° helix and 10° rake optimize chip control and finish quality, making it a solid choice for both production runs and precise maintenance work.
