The main types of milling cutters for aluminum

Seven Aluminum Milling Cutter Types

Aluminum milling cutter types include single-flute, two-flute, three-flute, roughing, finishing, ball nose, chamfer, and face milling tools. Single- and two-flute cutters provide maximum chip space for routers and high-speed spindles, while three-flute designs can raise feed capacity when evacuation and machine rigidity are adequate.

Roughing cutters remove stock quickly, finishing end mills improve walls and floors, ball nose tools machine contours, chamfer cutters deburr edges, and face mills cover broad surfaces on rigid machines. Choose polished carbide geometry or a coating suited to nonferrous metals, and avoid coatings that encourage aluminum adhesion. Match diameter, flute count, cutting length, helix, and corner style to the part. Verify chip load, coolant or air blast, runout, projection, workholding, spindle power, chip evacuation, and guarding before production. A reliable cutting tool supplier can recommend suitable options. Established milling cutter practices improve finish, productivity, tool life, and safety.
