Double Tube Mining Drilling Tools TW Series Core Barrel For Surface Wireline Borehole Drilling
>> Introduction
Overshot is a necessary device in wireline drilling. It's dropped on a cable and directly couples onto and lift up the inner tube assembly, eliminating the need to couple and uncouple the rod string each time the core is retrieved.
Ezy Lock Overshot is a modified product based on compact overshot. It protects against accidental release of the core barrel. This is ideal for suface application when hoisting above ground. TW series overhshot are available in BTW,NTW and HTW size.
