The URC Underreamer Concentric is a Ring Bit System is composed of a removable outer ring that attaches to a driver and used with a down hole hammer and casing driver. Its purpose is to underream for casing installation. The ring bit fastens to the driver bit with a press fit which prevents the ring bit from falling off. This system enables a driller to both drill and case simultaneously leaving ...

Rotary technology uses a sharp, rotating drill bit and downward pressure to cut, or crush, through the subsurface. Impact energy is supplied to the drill bit from either an above ground or down hole impact hammer. This impact force aids in the drilling. Depending on the competency of the substrate, the drill casing is advanced as the hole is cut, keeping the hole open during drilling. Competent ...

Hollow stem auger drilling is a proven and relatively inexpensive technique for a wide range of environmental and geotechnical applications including: sampling, installation of monitoring wells and data collection instruments, and subsurface improvements. Hollow stem auger drilling employs flighted tubing (augers), a cutter head and rotation to advance through the formation and remove the drill ...

Ready to Grout: Secant, Micropiles, Pilings, and more. Grout Through technology comes standard in all of our down hole hammers. Traditional check valves in the top are distributed around the bottom of the inner barrel instead. With Holte valving technology, DHHs minimize entry of water and debris into the operating portion, creating extended hammer life. This innovation also facilitates grout ...

Direct push technology, often referred to as DPT, uses the static weight of the rig combined with a hydraulic hammer to advance tooling or instrumentation through the subsurface. Unlike rotary, the drill cuttings are not removed from the hole. The speed and depth of penetration is largely dependent on the soil type, the size of the sampler, and the weight and power of the rig. These systems ...
