Holte Manufacturing products

Holte’s Dual Wall Drill Pipe with Quick Release Hex Head was created by Holte Manufacturing as a solution to the problem of thread binding. This is particularly a problem with large diameter systems using traditional threaded joints due to the higher amount of torque applied to the drill string.

Holte’s Underreamer Eccentric oval shape is designed to have a wide cutting edge on the borehole wall to maximize the underreaming.  It is ideal for sensitive overburden conditions. The Holte Percussion Underreamer Eccentric is a two piece tool, a driver section & a bit section. The driver, or splined section fits into a down hole hammer.  Available in a Drive Shoe Style or for use with a Casing Driver.

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 only the ring in the hole when the job is completed. This ring portion of the bit is larger in diameter than the casing and has a smooth round outer surface.
