• Hougen has been making "12, 000-series" annular cutters since we invented them in 1974. At one time, our president was putting the tooth geometry on every hougen cutter in the world
• 3/4" two flats for cutter mounting, o. D. Margins, i. D. Margins, fully fluted tools, patented tooth geometries, material types, coatings, and resharpenability
• Hougen cutters with the hougen-edge, feature a patented tooth geometry that provides long tool life, less chatter, and extended resharpenability
• Compared to traditional tooling (twist drills, etc. ) hougen cutters can multiply your cutting speed by up to 3 times. And you get longer tool life, a more accurate hole, a better finish, with no burrs
• Hougen cutters maximize feed rates because up to 10 or more cutting edges distribute the cutting load evenly. By converting a smaller area to chips, hougen cutters require less horsepower and thrust. American made
