Solid Carbide High Feed Endmill
High feed geometry is producing a positive cutting edge out of a series of continuous radii with no tangent point to induce wear. This cutting motion allows the use of heavy chip loads to achieve very high feed rates.

High Feed Machining is used to rapidly machine to net shape on complex 3D part geometries. It utilizes a light depth of cut at a high feed rate to produce large metal removal rates. The cutter cusp left by a high feed machining approach are small and often allow for process reduction or “rough to finish”.
Computer Aided Manufacturing Radius (CAM R)

MILLSTAR high feed geometry is designed from a series of continuous radii with no single point to induce wear. For users without tooling measuring systems, MILLSTAR provides a computer aided manufacturing radius (CAM R). The CAM R will allow programmers and machinist a theoretical radius for programming purposes. Depending on diameter, the CAM R will leave the workpiece in a +0.0003 to +0.0005 plus stock condition.
