Company Introduction : Diyfia Company: 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.
