Radius Milling Cutters

Precision solutions for machining external radii on Stainless Steel, Hardened Steel, and Aluminum.

Our Solid Carbide Convex Radius Milling Cutters (also known as Corner Rounding End Mills) are engineered for high-precision external rounding and fillet machining. Crafted from premium sub-micro grain carbide, these tools offer the extreme rigidity and wear resistance required for high-speed CNC machining.

Description

Material Compatibility:

Hardened Steel (Up to 55+ HRC): Exceptional performance on mold and die steels.

Stainless Steel & Heat-Resistant Alloys: High thermal stability for clean, burr-free edges.

Aluminum & Non-Ferrous Metals: Optimized geometries to prevent chip welding and ensure a mirror-like finish.

Key Advantages:

Perfect Corner Rounding: Delivers consistent, smooth convex radii for external edge finishing.

Superior Tool Life: Solid carbide construction provides significantly higher feed rates and durability than HSS

Advanced Coatings: Optional AlTiN or TiAlN coatings for high-temperature resistance and extended tool life.

Smooth Fillet Machining: Engineered for precision deburring and creating aesthetic, safe rounded corners.

Technical Specifications:

Radius Range: Available in a wide range of standard and custom radii.

Machine Compatibility: Ideal for high-speed CNC Machining Centers, as well as manual and semi-automatic milling machines.

Expert Non-Standard Customization

As a specialized manufacturer, we provide custom solid carbide radius cutters. We can produce non-standard radii, specific shank diameters, and specialized flute lengths according to your technical drawings.
