[0002] A reamer is a rotating tool with one or more teeth used to remove a thin layer of metal on the surface of a processed hole. The outer blade is generally divided into two types: straight blade or spiral blade. During the automobile processing process, it is generally necessary to open or expand a hole at a certain position of the automobile parts. At this time, a cutter head and a reamer will be used. Regardless of the purpose of the reamer, it is a precision tool.

[0003] In the prior art, a drill reamer with easy chip breaking disclosed in announcement number CN219665211U is also a reamer, including a tool rod, one end of which is provided with two main tools and two auxiliary tools. The outer diameter of the auxiliary blade is larger than the outer diameter of the main blade, so that the main blade is responsible for rough machining and the auxiliary blade is responsible for fine machining, so that the drill cutter and reamer are merged, and a first chip groove, a second chip groove and a chip breaker groove are provided to enable normal chip breaking and chip removal of iron chips, avoid iron chips entanglement with the tool, and ensure the quality of hole diameter machining.

[0004] When the above scheme is in use, two main edges and two secondary edges are arranged on one side of the tool rod, wherein the main edges are responsible for rough machining and the secondary edges are responsible for fine machining. However, since the tool rod and the two main edges and the two secondary edges are an integral structure, after the reamer is used for long-term machining, the main edges and the secondary edges will be worn. Thus, when replacing, only the entire tool rod can be replaced, which is wasteful of materials. In view of this, a diamond reamer for automobile machining with a cooling inner cavity structure is provided to overcome the above-mentioned defects. Utility Model Content
