Designed for lasting durability, the Barbco BBC25 Dirt Cutting Head withstands your most demanding auger boring job. Built with an initial 1-1/2” thick A36 steel plate, reinforced with a second piece of steel for a study 3”-thick cutting head. Easily extend the life of your cutting head by replacing the hex drive, wings and cutters, as needed. Customize your cutting head order with extra banks or an optional drift reducing ring. When used correctly, cutting head rings enable the tool to concentrically cut a hole in front of the casing, significantly reducing the drift to the right.
