Decrease the rotation when encountering extremely hard rock conditions. The EXTReam works best with low pullback pressure and low rotational torque. A variety of different size nozzles and plugs that can be used to reconfigure the water ports based upon the volume of mud being pumped and the conditions encountered during the pilot bore. The EXTReam is delivered from the factory with most of the side and rear water ports plugged which forces most of the flow out the front to properly mix the cuttings. The EXTReam is a true horizontal rock reamer and comes with two types of teeth with the EXTReam: a pointed tooth for softer rock, and a rounded tooth for harder rock. The EXTReam has proven itself in field tests in cobble, soft to medium rock, and hard rock. The EXTReam boasts no moving parts – at the end of a backream, simply replace any worn teeth and the EXTReam is ready to go again. Their proven ruggedness and versatility provide HDD contractors the most cost effective cutting tool for drilling rock applications. Drill Bits are available in a variety of cutting structure designs specific to different rock types. All the other components work in conjunction with the drill bit to cut the rock face. Pilot Hole Drill Bits are key components of the drilling package. INROCK has the expertise to assist you in selecting the correct bit for the formation or to design pilot hole drilling assemblies to provide the lowest drilling cost per foot. INROCK has a complete assortment of drill bits for drilling formations from soft soils to ultra hard rock, applications with motors, steerable jets, or straight boring. The Iron Fist is one tough, long-wearing bit. The Iron Fist features wrench flats for easy removal, a built-in check valve and ¼ inch recessed water holes to prevent clogging. Cutters are strategically placed to protect the edges of the steer face. Balanced, compact cutters facilitate downhole stability and are less likely to hang up on cobbles. The main carbide cutters in front are positioned to allow the operator to “rock” the bit through rock and cobble. The contoured design and carbide cutters make the Iron Fist ideal for cobblestone conditions. When you encounter cobbles and rocky conditions and need a successful bore the first time out, the bit you want at the end of your drill stem is Melfred Borzall’s new Iron Fist. By providing a ready supply of energy when the driller needs it, there aren’t any stressful “trip-outs” or replacing of expensive batteries. Since power is not produced when the drill stem is not being rotated, Armadrillco also includes a rechargeable power cell to operate the transmitter when the drill stem is steady. This provides the relative motion between the rotor and the stator that is needed to produce power. Operationally, the Generator rotates with the drill stem as a counterbalance that is attached to the rotor is held in-place by gravity. 800.324.4930, Īrmadrillco has discovered that by combining the proper generator, the correct gearhead and a suitable counterbalance, sufficient power can be provided to operate a Transmitter indefinitely. Features include a perimeter flow to create a complete slurry replaceable jets carbide chip leading edges to extend the life of the tool and an integrated pulling eye. Excellent for use is dirt, shale, sand, gravel, cobble and sandstone, the V-ROCK survives in limestone, glacial till and intermittent hard rock. The V-ROCK by American Augers is the tooling to have when unmanageable ground conditions threaten the success of any jobsite project. A replaceable three-tooth design delivers a consistent cutting structure for steering corrections and maximum drilling performance. Carbide buttons are strategically placed on the bit for optimum cutting, and carbide hard facing helps to enhance wear and performance characteristics. The Gauntlet bit is designed for use in soft to medium rock, shale, hard pan and caliche ground conditions up to 10,000 psi with exceptional steering capabilities. The system features four distinct bits for use in specific ground conditions. The Armor Drilling System is a single HDD tooling system with multiple drilling options. Ballantine has taken its market leading HDD collar and made it even better by adding small terminator teeth to the back side of the collar to protect the tool joint from rocks and debris during pull back. Downhole tools from Ballantine, Vermeer, American Augers, Armadrillco, Melfred Borzall, INROCK, Railhead Underground Products, Sharewell, HammerHead Trenchless Equipment, Ditch Witch and Drillhead Directional.īallantine, known since 1959 as a manufacturer and marketer of ground engaging replacement wear parts for the trencher and horizontal directional drilling tool market announces the new Hurricane Collar.
