BQ impregnated diamond core bit
Brief Introductions of Impregnated Diamond Bits
The impregnated diamond bits are cutting tools. They contain diamond segments bonded to a base material. They are widely applied in cutting non-ferrous materials. The selected grades of synthetic diamond of high quality are distributed in the depth of impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond. This diamond tool is widely applied in the mineral exploration industry.
The main crown technical parameters of impregnated diamond core bits include diamond grade,size,concentrarion 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 waterways,and gage stones are a bit larger.
