Core Drilling Accessories

An overshot is used to connect and lift the inner tube assembly on the wireline cable during core retrieval.

Head assembly, inner tube, core lifter case, core lifter, and stop ring are commonly listed as the core inner-tube components.

Hoisting plugs, tube wrenches, and vice-grips are commonly offered to improve lifting safety and speed during make/break work.

Spare core lifters, stop rings, liners, and overshot wear parts are usually stocked, because recovery issues are solved there first.
