HWL HWL-U Ezy lock wireline overshot mineral exploration geotechnical drilling

HQ BQ NQ PQ BQU NQU HQU NQ3 HQ3 PQ3

When the inner-tube is full, a device called an overshot is lowered down the hole via a wireline cable and brought to the surface by use of a winch.

Once the inner-tube assembly is at the surface, an empty inner tube is lowered into the hole so drilling can resume

A Overshot is available for each size of core barrel. This is the retrieval device lowered on the wireline to recover the inner tube assembly containing core.
