Amana Tool Carbide Tipped Bullnose 3/8 Radius x 1-3/8 Diameter x 1 5/16 x 1/2" Shank

Shape the full edge of a workpiece with a bullnose radius bit. Ideal for shaping stair treads, window sills, table and counter edges, shelves, and making moldings. The "nose diameter" (M) is the thickness of stock that can be nosed, i.e., given a full 180-degree round over. Flats at top and bottom of the cutting edges create fillets on stock thicker than the nose diameter. Must be used with an edge guide on handheld routers or the fence on a router table. ‘M’ denotes thickness of material on which a full 180° round over can be accomplished. Maximum RPM 20,000.
