This cutter is engineered to deliver consistent, precise keyways with stable performance across a range of materials. The cobalt‑based HSS‑E core provides enhanced wear resistance for tougher jobs, while the 10° helix reduces cutting forces and improves chip evacuation for smoother finishes. The Weldon flat on the 10 mm combi shank, combined with threading, ensures secure seating in tool holders and minimizes runout during heavy milling. DIN 850 compatibility means straightforward interchange with standard holders on compatible machines, making it a dependable choice for gear production, shaft machining, and other precision keyway applications.
