Core Drilling Accessories PWL / PWL3 Impregnated Diamond Core Cutting Drill Bits

 

Wireline core drilling systems are used for medium to ultra-deep boreholes, which provides the most efficient core sample extraction from the rock mass without pulling the entire drill string. The rock sample is removed from the bottom of the hole in the inner tube assembly by an overshot on a wireline cable.

 

Impregnated Diamond Core Bit is made with high quality synthetic diamonds, mixed evenly through a metal alloy matrix. Using hierarchical mole technology, to reduce the contact area of diamond bit matrix and the labial surface of the rock surface, and improve the drilling speed. The diamond bit mole with steel layer, to increase the pressure applied to the rock drill lip, improve the drilling speed of the drill bit. Put the first-grade abrasive-high strength, coarse grain diamond and two grade abrasives -low strength, fine grain

diamond in the diamond bit, to improve the life of diamond bit.
