AQ/BQ/NQ/HQ/PQ impregnated diamond core bits for mining

Manufactured with very small, high quality synthetic diamonds mixed evenly through a metal matrix. The matrix hardness is chosen to suit the rock formation, so that it wears evenly throughout the life of the bit, exposing new sharp diamonds.

The main crown technical parameters of impregnated diamond core bits include diamond grade,size,concentrarion and quality,matrix hardness and crowm shapes.The users can make rational selections according to the formations to be drilled.To avoid excessive bit wear,tungsten carbide inserts are used on both sides on the waterway,and gage stones are a bit larger.

Advantages:

· Resists abrasion, OD and ID gauges last longer

· Better core recovery

· Higher diamond concentration for increased life and penetration rates

· Lower fuel consumption and less equipment wear

· Simplified matrix choice reduces inventory costs
