Hougen's Copperhead annular cutter, measuring 2-1/8 inches in diameter with a 2-inch cutting depth, is built for demanding metalwork. Its carbide tip is designed to hold up on abrasive and tough-to-cut materials such as stainless steel and cast iron, helping extend tool life. A special tooth geometry supports better chip flow during cutting. The 3/4-inch two-flat Fusion2 shank fits Hougen magnetic drills and one-touch arbor systems.
