Rock Construction Equipment and Tools: American Augers
The Heavy Duty Rock Head (Christmas Tree Head) is a durable cutting head that is ideal for bores through soft rock formations, harp pan, shale, gravel, small boulders and other intrusive ground conditions up to 6,000 psi.
The design benefit is that the “vee” shape of the head provides a self-centering action, which helps to maintain ideal line and grade. The cutting head features Tungsten carbide bullet bits that can be used at aggressive drill angles. Available in diameters from 8 to 66 inch – depending on the size – is designed with a 2 ¼-, 3-, 4- and 5-inch hex. 800.324.4930, www.americanaugers.com
