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 inches – depending on the size – is designed with a 2 ¼-, 3-, 4- and 5-inch hex. 800.324.4930, www.americanaugers.com

Sharewell
Sharewell offers a 5-cutter version of its Jumbo Lo-Torque Hole Opener product – the LTX24x5. This version dramatically reduces impact loading on the cutters, which increases the product’s working life. The 5-cutter version also reduces the torque cycle while reaming, creating a very smooth running hole opener. The body is bi-directional and can be either pull or push reamed. Ideal for pipeline projects, the Jumbo cutters offer large, sealed bearings for extended runs. It is available in Mill Tooth style, IADC type 5 T.C.I., and IADC type 8 T.C.I. A minimum pilot hole of 26 inches can be made using the LTX24x5, and hole sizes ranges are 36, 38, 40 and 42 inches. 713.983.9818, www.sharewell.com
