Non-rotating "triangular" carbide bits for motor graders and groomers have great penetration and wear life. The carbide teeth are made up of steel and carbide inserts that allow for these bits to hold up well in all conditions and applications. These carbide bits hold in the board with a universal snap ring so they are easy to change out. Non-Rotating carbide bits are what we recommend for front mount grader groomers. They can also be used on the moldboard of a motor grader for extreme wear life.
