Summary:The invention relates to a tubular reamer for drilled hole shaping. The tubular reamer comprises a reamer body which is of a tubular structure, the lower end of the reamer body is connected with a drilling tool, the tube wall of the reamer body is provided with multiple rows of mounting holes distributed in the axial direction of the reamer body, and alloy blocks are fixedly connected into the mounting holes. The tubular reamer is combined with the drilling tool, reaming is carried out on expanded holes, and shaping is conducted on the drilled holes; compared with traditional single drill-bit reaming, quality of the drilled holes is greatly improved.
