Impregnated Single Pipe Diamond Core Drill Bit (DH75)


The impregnated diamond 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.

Main type of diamond drill bits;

Electroplated diamond bits; Hot-pressed diamond bits; PDC drill bit

Single pipe and double pipe diamond core drill bit, wire-line diamond core drill bit

Electroplated Diamond Reamer shell , Sintered Diamond Reamer shell,   

Use for Diamond Core Drill Bits:

DIYFIA core bits can drill a broad range of geological formations from the softest to the hardest rock, widely used in all kinds of drillings for geological prospecting works, drilling on hydrology, water wells and big calibers. It has been widely used on areas such as road and railway construction, water resources and hydropower and architecture, taking out rock core to examine ,etc. 


Structure of Diamond Core Drill Bits :

All the parts are an integral whole one, easy to operation, with high quality synthetic diamonds mixed evenly through a metal matrix. Our core bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum. 

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.
