Mills Machine Company Flightless Cutter Heads
February 10, 2020
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
