Overview of Matrix Body PDC Bit GM1605T


Matrix body PDC bit GM 1605T is made by Tungsten carbide powder, this type of matrix body bit is very high hardness material, mainly used for deep Oil&Gas well drilling.


GREAT will first provide a 3D drawing according to the customers' request, then optimized design to achieve more footage and longer working life, higher effective works. It is manufactured by mold process of PDC bit crown. The connection of this type of diamond PDC bit is made of AISI 4145H round steel and has heat treated. Threads are machined into the blank and the pin is threaded to the bit head. Joints should strictly comply with the API standard and should be inspected one by one with thread gauge and Thread Inspector.


According to the customer request, we have China PDC cutters, America PDC cutters welding to the bit body.
