Overview
The Weldon EDP 27042 HSS ball end mill is a high-speed steel cutting tool engineered for precision CNC and manual milling operations. This double-end, 2-flute ball-nose end mill combines proven Weldon EDP 27042 specifications with a reliable Weldon flat shank to prevent slippage in modern machining centers. The ball-nose geometry makes it ideal for 3D contouring, radius work, and curved-surface finishing on ferrous and non-ferrous materials.
Key Features
- 2-flute design for efficient chip evacuation and consistent surface finish
- 1/2″ cutting diameter with 1/2″ Weldon shank for secure, positive tool holding
- Right-hand cutting and right-hand helix for optimal performance
- HSS material offers superior wear resistance at lower cost than carbide
- Ball-nose profile cuts curved surfaces and contoured features
- Double-end construction maximizes tool utilization
