The precision-ground concave cutting profile forms a controlled corner radius along external edges, while the 4-flute geometry provides repeated cutting engagement for edge radiusing, profile finishing and mold-component machining. Solid carbide construction provides the rigidity required for CNC milling, with tool geometry and coating selected according to the workpiece grade, hardness and required edge finish.<\/p>\n<p><!-- KEY CONFIGURATION --><\/p>\n<div style=\"display: flex;
