ISO HQ rock bits  for geological field   


Introduction :


Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the

rock. In most geological formations, impregnated bits are more economical to use than other bits.





They are manufactured with very small, high quality synthetic diamonds mixed evenly through a metal matrix. DIYFIA core bits are manufactured to give optimum penetration rates and bit life, which is

required to keep the cost of diamond drilling to minimum.


About DIYFIA Group:


Nearly 57 years of experience combined with recent improvements in technology and manufacturing concepts have resulted in greatly improved drilling performance of impregnated PQ HQ NQ BQ diamond core bits.


High quality synthetic diamond powders are distributed in the depth of impregnated diamond core bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond.


The matrix of our impregnated diamond core 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.




1.Fast cutting and drilling speed 

2.Long life, stable performance 

3.Low power consumption

4.Professional OEM, superior grade quality, more than 57years manufacturing experience

5..CE: ISO: 9001: 2000
