The Dormer Pramet C822 Woodruff Cutter is a precision, single-tooth tool engineered for accurate keyway milling in a range of metals. Designed for both CNC and manual machines, this HSS‑E cutter delivers dependable performance with a screwed 10 mm combi shank for secure mounting.

• Diameter: 22.5 mm
• Width of cut: 5 mm
• Overall length: 63 mm
• Shank: 10 mm combi shank with Weldon flat and thread (screwed shank)
• Material: Cobalt-based HSS-E with bright finish for improved hot hardness
• Helix angle: 10°
• Rake angle: 10°
• Standard: DIN 850
• Applications: Keyway milling in steel, cast steel, stainless steel, cast iron, non-ferrous metals and high-temperature alloys

Ideal for shops that require precise, repeatable keyways, the C822’s cobalt-enriched HSS-E composition provides enhanced heat resistance and edge retention during high-speed milling. The 10° helix and 10° rake optimize chip evacuation and reduce built-up edge, helping you achieve clean, accurate slots with fewer passes. The robust screwed shank with a Weldon flat ensures stable alignment and minimal runout in demanding setups, making it a reliable choice for both new work and maintenance tasks on metal components with critical tolerances.
