This cutter is designed to deliver consistent, accurate keyway dimensions across demanding materials. The cobalt-based HSS-E construction provides enhanced wear resistance for longer tool life, while the 10° helix and rake angles promote smooth chip evacuation and reduce cutting forces. The Weldon-flat, threaded shank ensures a secure fit in compatible tool holders, minimizing runout during precision milling. With a practical 63 mm length and DIN 850 compatibility, it fits common industrial setups and supports reliable, repeatable performance in daily workflows.
