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 of the waterway, and the gage stones are a bit larger.
stepped imgregnated diamond core bits are used for drilling hard or fractured formations, these bits can increase the free cutting face area, bit stability and penetration rate.
serrated profile impregnated bits are suitable for hard dense formations
tapered imgregnated bits are suitable for soft and medium hard formations.
