BQ NQ HQ PQ Wireline Drill Rod Core Barrel Assembly and Outer tube series
Specifications:
1. high quality alloy tube
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads
Wire-line core drilling tools can lift core from drill rods without picking up coring system.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 core recovery ratio, long bit life and lower labour intensity.The advantages can get more clear with the increasing of drill hole depth.
