The main crown technical parameters of impregnated diamond core bits include diamond grade,size,concentration and quality,matrix hardness and crown 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.
