Product Description
With bottom discharge HMLC diamond core bits, which is suitable for triple tube core barrels, to improve the flushing fluid's erosion against the core during drilling.
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.
Sizes Available:
