Involute Gear Cutters are the best way to make a gear on your mill. Simply put the cutter on an arbor in your spindle, mount your gear blank in a rotary/indexer, and cut the teeth! We offer a variety of gear cutters in different modules, pitches, and pressure angles. Each cutter can make gears of a certain range of teeth. We built a tool to find the right cutter and if you need help, please contact us and we'll be happy to help!
