INROCK’s Standard Rock Reamers are fabricated using only “new bit” sealed bearing drill bits sections. Proper tool design, welding techniques, heat treating and hard-facing are critical during the fabrication process to ensure tool strength, cutter integrity and bearing life. Understanding downhole torsional stress and vibration effects on welded components is vital in providing reliable standard rock reamers. 713.690.5600, inrock.com

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, the rock head is designed with a 2 ¼-, 3-, 4- and 5-inch hex. 800.324.4930, americanaugers.com

Sharewell
The 5-cutter version of Sharewell’s Jumbo Lo-Torque Hole Opener product – the LTX24x5 – reduces impact loading on the cutters, which increases the product’s working life. It 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, sharewell.com
