Which has a shallow parabolic profile and medium cutter density,designed for coring the medium hard
formation.Utilizing different patented PDC cutters enhance the bit's ability to drill in hard formations.


High quality TSP in the inner blade and gauge has high wear-resistant for longer bit life.
The unique nozzle design improved the cleaning and cooling,enhanced the ability cuttings evacuation.

Manufactured with very small, high quality natural diamonds mixed evenly through a metal matrix. The matrix hardness is chosen to suit the hard rock , so that it wears evenly throughout the life of the bit, exposing new sharp diamonds for cutting the formation efficiency.
Impregnated bits are designed to work as grinding tools and must work at relatively high rotation speeds, high bit loads compared to other types of diamond bits. It is essential that impregnated bits are well-cooled by the flush to prevent premature bit failure (air flush cannot be used with impregnated bits).


Advantages:
Ultra-abrasion resistant
Maximize penetration rates
Much lower cost per metre compared with diamond core bits imported from emerging economies
Acquire better core.
