Under Reamer Drilling Tools
For Overburden Well and Hole Drilling Systems

Drilling through Overburden presents unique challenges on any job. Since drilling cased holes with a DTH - Down The Hole Hammer - has become the preferred way to get through unconsolidated ground it is imperative that drillers have a choice of systems to use. We have developed the following underreaming systems with that in mind:

URE - Under Reamer Eccentric

URC - Under Reamer Concentric

URG - Under Reamer Gauge (now available in RC and with 4 arms)

Whether it makes sense to have a fully recoverable system or one that partially remains in the hole after the casing is installed choosing one of Holte's innovative, proven systems will ensure you get the job done efficiently and well ahead of the competition.
