Mills Machine Company’s Flightless Cutter Heads were created primarily for environmental drillers on the West Coast, but are rapidly becoming popular in other parts of the country. These bits feature a stronger body design and longer cutter block life. The flightless design efficiently removes cuttings, resulting in better penetration and durability. These bits are available with two- or three-key design, and in any size or style. www.millsmachine.com
