Product Description

Our 4-flute carbide stepped ball end mill is engineered for high-precision 3D contouring, multi-level radius cutting, and complex surface machining. Made from ultra-fine grain tungsten carbide, this forming cutter features a unique stepped design that enables smooth transitions between different radius levels, making it ideal for mold making, aerospace components, and precision engineering.

With TiAlN coating (optional) and optimized 4-flute geometry, it provides superior chip evacuation, reduced vibration, and extended tool life in hardened steels (up to HRC55), aluminum, and other engineering materials. Available in diameters from 2mm to 12mm, it is compatible with CNC machining centers, high-speed milling machines, and industrial routers.

Key Features

Multi-Level Stepped Design - Allows complex radius profiling in a single operation, reducing tool changes.
4-Flute Carbide Construction - Ensures high feed rates while maintaining excellent surface finish (Ra ≤ 0.8μm).
TiAlN Coating Option - Enhances heat resistance and wear resistance for steel machining.
Precision Ground Cutting Edges - ± 0.005mm tolerance for accurate 3D contours.
Balanced Helix Angle (30°-35°) - Reduces cutting forces and tool deflection.
Wide Diameter Range (2mm-12mm) - Suitable for detailed engraving & heavy-duty milling.

Product Advantages

Efficient Multi-Level Machining - Combines multiple radii in one tool, saving time.
Superior Finish - 4-flute design reduces tool marks for smoother surfaces.
Long Tool Life - Carbide + TiAlN coating resists wear in tough materials.
Versatile - Works on steel, aluminum, titanium, and composites.

Typical Applications

Mold & Die Making - Complex cavity finishing, radius blending.
Aerospace Components - Turbine blades, structural parts.
Automotive Prototyping - Curved surfaces, intake manifolds.
Medical Device Machining - Implants, surgical tools.
General Precision Engineering - 3D sculptures, industrial design.
