Diamond Impregnated Bits, Reaming Shells & Casing Shoes

Impregnated Diamond Bits - are available from USExploration Equipment Company in support of your consolidated formation exploration and sample recovery requirements in a wide range of configurations.  When ordering make sure you know as much about the formation as possible…then match your Coring System (NQ-Series or HQ-Series), select a Bit Matrix that fits the hardness level (Series-1 for soft through Series-10 for ultra hard), determine whether your Bit Gauge (actual hole size) should be larger then, equal to or less then the Gauge (S, R, OS or -R) being cut by your Reaming Shell, choose how thick your matrix should be, based on anticipated bit wear (6mm, 9mm, 12mm or 25mm), select a Waterway configuration (TW, FD, DD, EX or Staged) based on your experience in the formation and finally the number of Waterways and their respective depth…call us for a quote today, on the Impregnated Bit that best fits your application Back to Top         PDF

Reaming Shells for your NQ, NXB, NV & HQ-Series Core Barrels

Diamond Reaming Shells - are available from USExploration Equipment Company in support of your consolidated formation exploration and sample recovery requirements in four basic configurations…Impregnated, Broached, the Magnum Series and finally the Premium Series.  A Reaming Shell is designed to sit above the Diamond Bit or high on the Outer Tube in an effort to increase stability, reduce vibration and maintain desired hole gauge.  The Magnum Series and Premium Reamers both utilize tungsten carbide to better absorb impact and decrease erosion of the outer pad itself.  When ordering, simply select the correct Coring System (NQ-Series or HQ-Series), the Reamer Type based on the formation you will encounter, select a reamer that will cut the Gauge required, and finally determine whether you will need two reamers (Reaming Shell and Adapter Coupling) or just one…               Back to Top           PDF
