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. We can supply BQ NQ HQ overshot Assembly.
Type of the bit matrix The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action, also with long life using time is important, meanwhile it will keep the cost of diamond drilling to a minimum. The optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of the formation to be drilled.
