China Ltk48 Impregnated Diamond Core Bit

LTK diamond core bits are suitable for the drilling of the LTK double tube core barrels,They offer a cost effective,high production,which is designed for optimum production and core recovery in medium to extra hard rock formations. Available sizes 48 and 60mm.
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.
