The Armor Drilling System from Vermeer is a single HDD tooling system with multiple drilling options designed to provide versatility and performance, and the integrated modular design allows the tooling to be adapted to various ground conditions. For soft to medium rock, shale, hard pan and caliched ground conditions up to 10,000 psi, use the Gauntlet bit. Carbide buttons are strategically placed on the bit for optimum cutting, and carbide hard facing helps to enhance wear and performance characteristics. A replaceable three-tooth design delivers a consistent cutting structure for steering corrections and maximum drilling performance. The Armor Drilling System is also available in 2- and 4-battery sonde lengths and is wire line compatible. 888.837.6337, www.vermeer.com

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 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
Kennametal’s new line of cutting tools for directional drilling and drilling back reamers offer excellent cost savings, long tool life, and outstanding impact strength in the most challenging drilling conditions. Buttons and compacts have rock-style heads made of durable carbide and are engineered for the hard daily punishment of drilling rock and concrete. Protect directional drilling back reamers from wear in abrasive conditions with the solid carbide tips and steel bodies on the welded-on teeth extend back reamer tool life.
The Cat G130B Contractors’ Grapple is a heavy-duty, durably constructed tool designed for structural demolition, material handling and utility application, such as sorting and loading rock, scrap and construction debris. The Cat G130B works ideally with a range of models in the Caterpillar medium-hydraulic-excavator lineup. The Cat G130B uses a two-over-three tine configuration that allows the three tines on the slightly curved lower jaw to sink easily into scrap piles, while a pair of tines on the interlocking upper jaw exerts ample hydraulic power to retain material securely on the large working surfaces of the jaws. Abrasion-resistant AR 400 steel, used for tine tips, wear plates and wrappers assures durability in the harshest environments. The flush design, coupled with the precise curvature of the lower jaw, assures that material slides out with no obstruction when the grapple dumps. www.cat.com
The Aggressive Talon Rock Bit is a multi-use bit manufactured for HDD applications in a variety of soil conditions, including sandstone, shale and chunk rock. The bit’s thread-on shank provides even greater reliability and durability in tough digging conditions. The Aggressive Talon Rock Bit features four replaceable carbide-tipped cutting teeth in front of the tool that enable it to operate more smoothly with less drill pipe chatter. The angle of the cutting teeth enables it to more effectively carve into rock. Carbide buttons in the abrasion-resistant, steel-bit body reduce wear when working in tough conditions. 800.654.6481, www.ditchwitch.com
