4 Flute Corner Radius End Mill HRC55 for Aluminum
Corner Radius End Mill: Ideal for rough machining, plane finishing, and side finishing of mold bases. Exceptionally suited for rough machining molds made from high-hardness materials. When milling similar workpieces, the round nose cutter maintains a consistent cutting speed at four points, resulting in superior machined surface quality compared to ball cutters. Additionally, it retains the bottom surface milling capability of an end mill, enabling the processing of relatively flat surfaces with faster milling speeds.
