Key Technical Advantages

3 Precision Cutting Edges: The triangular positive design offers three high-utilization cutting edges, delivering excellent economic value for shoulder milling operations.
Sharp Helical Edge Geometry: Features a high positive rake that lowers axial and radial cutting forces, ideal for high-speed, light-cutting applications.
Stainless Steel & Alloy Specialist: Specifically optimized for gummy and difficult-to-machine materials, preventing chip re-cutting and built-up edge (BUE).
Perfect 90° Shoulders: Engineered to provide exceptional squareness and surface finish on vertical shoulders, reducing the need for secondary finishing.
Low Spindle Load: The sharp cutting action significantly reduces power consumption and heat generation, extending both tool and machine life.
