NW Impregnated hard rock Casing shoe drill bit for Exploration Core Drilling
Casing shoe drill bit
Our impregnated diamond core bits are the most commonly useful bits
in the mineral exploration industry, as they have the widest range
of application. The carefully selected grades of high quality
synthetic diamond are distributed in the depth of impregnated bit's
matrix series. The matrix layer of the "ROSCHEN" contains a uniform
distribution of these crystal that are embedded in a powdered metal
bond.
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.

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.
