Ball nose end mills, also known as full radius end mills or ball mills, are cutting tools where the nose radius is equal to half of the diameter of the tool. This creates a constant single radius (or ball) at the tool end with no straight edge (sharp corners) in the profile. They are used for a host of milling operations from contouring and profiling to slotting and corner picking. Their primary application is in 3D semi-finishing and finishing operations for industries like Mold & Die, where the very nature of their shape can be used to more efficiently machine part contours. Just enter your required dimensions of your custom cutting tool and our application engineers will design and quote for your application.
The Ball Nose End Mill is a precision-engineered cutting tool designed for 3D contour milling, surface profiling, and machining complex geometries in molds, dies, aerospace components, and general CNC applications. Its hemispherical cutting profile enables smooth transitions along curved surfaces, delivering excellent surface finish and consistent dimensional accuracy. Aoshiji® Custom Tool provides application-specific geometries tailored to print, ensuring reliable performance across a wide range of materials and machining strategies.With its stable cutting geometry and high radial accuracy, the ball nose end mill ensures uniform contact across 3D surfaces, supporting predictable tool performance in demanding multi-axis machining environments.
