Diamond Core Drilling Tools » Wireline Coring Systems

A very efficient coring technique called wireline coring, makes it possible for the core sample to be retrieved from the bottom of the hole without removing the entire rod string. To retrieve the core sample, an overshot is lowered inside the drill rods on a wireline cable until it latches onto the spearhead point of the core barrel head assembly. Positive latching lifting dogs securely attach, and the core barrel inner tube containing the core sample is retracted to the surface using the wireline cable and winch.

Hole Products wireline coring systems are available in all standard DCDMA sizes. Optional thin kerf and triple tube designs are available to optimize productivity and core recovery in various formations.
