Abstract: An end mill configured as a high feed circle segment cutter and a high feed end cutter utilizable in 5-Axis machining. The end mill comprises the end work of a high feed mill and the fluting of a circle segment cutter, thereby allowing the operator to rough out the bulk of the material with a high feed method (small axial and larger radial depths of cuts), then use the side of the tool to finish/semi-finish the walls of the part with the circle segment cutter geometry on the side of the tool.
