Double edged ball end milling cutter, also known as R-cutter, is a type of tool assembled on a milling machine for milling various curved surfaces, circular arc grooves, etc

Seven Double Edge Ball End Mill Benefits

A Double Edge Ball End Mill has two cutting flutes and a rounded end profile for machining curved surfaces, circular grooves, mould cavities, reliefs, and three-dimensional contours. The ball radius allows smooth directional changes, while two flutes balance cutting capacity with chip space for dependable roughing and finishing in compatible materials.

Key benefits include smooth contour tracking, efficient chip evacuation, stable cutting, predictable radius generation, good surface finish, versatile 3D machining, and balanced productivity. Diameter, ball radius, flute length, helix, shank, reach, substrate, and coating determine strength, detail capability, material compatibility, and recommended cutting parameters.

Select the tool for the smallest internal radius and required reach, then minimize runout and overhang. Use appropriate step-over, depth, speed, feed, coolant, and chip control, and verify the toolpath before production. A specialized ball end mill supplier can support geometry selection.
