A complete set of wire-line drill tools include: Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench etc. It has some advantages such as high penetration rate, high penetration rate, high core recovery ratio, long bit life and lower labour intensity. The advantages can get more clear with the increasing of drill hole depth.

Wrenches

Wrench is used tighten or loose the tubes during drilling. Size available: wireline inner/outer tube wrenches, pipe wrenches, circular wrenches and rod wrenches     

Sub adapter

Adaptors are made of high quality alloy steel. Connections can be made as per client's request.   

Foot clamp
