Dormer Pramet C822 32.5mm x 8.mm HSS-E Screwed Shank Woodruff Cutter DIN 850

Meet the Dormer Pramet C822 Woodruff Cutter — a precision HSS-E tool designed for robust keyway milling in steel and alloys. With a 32.5 mm diameter, an 8 mm width of cut, and a 71 mm overall length, it’s built for reliable performance in demanding workshops.

• Diameter: 32.5 mm
• Width of cut: 8 mm
• Overall length: 71 mm
• DIN standard: DIN 850
• Shank: 12 mm combi shank with Weldon flat and thread
• Material: Cobalt-based HSS-E with bright finish
• Teeth: 12 teeth
• Helix and rake: 10° helix, 10° rake angle
• Applications: Keyway milling in steel, stainless steel, cast iron, non-ferrous metals and high-temperature alloys

Designed to deliver consistent, precise keyways, this cutter’s cobalt-based HSS‑E substrate offers enhanced wear resistance and thermal stability for hard metals and challenging alloys. The 10° helix reduces cutting forces and promotes smoother chip flow, contributing to cleaner edges and longer tool life. The Weldon-flat, threaded combi shank provides secure clamping in a variety of holders, minimizing runout and vibration during heavy milling. Suitable for steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, the C822 is a dependable choice for reliable, repeatable keyway milling results.
