H.S.S. Concave Radius Cutter End Mill

The H.S.S. Concave Radius Cutter End Mill is designed for machining external roundovers, convex radius edges, arc profiles, and formed radius cuts. Made from high-speed steel with a hardness range of HRC 62–65, this cutter series features an uncoated finish, right-hand cutting direction, and a Weldon shank for stable holding in milling operations. This concave radius cutter family is suitable for use on conventional milling machines, CNC mills, Bridgeport-style mills, and general milling equipment. It can be used for machining steel, aluminum, and stainless steel, and is available in radius sizes from 3/32" to 1/4". The specification sheet lists concave cutter items 2810-0332, 2810-0018, 2810-0532, 2810-0316, and 2810-0014, with 4-flute and 6-flute options depending on size.
