Inclined plane dovetail groove embedded type deep hole precision turning tool

The invention discloses an inclined plane dovetail groove embedded type deep hole precision turning tool. The Inclined plane dovetail groove embedded type deep hole precision turning tool is composed of a front tool rod and a rear tool rod, wherein the front tool rod is formed by modifying a commercial inner hole turning tool; an included angle of being 30+/-5 degrees is formed between the horizontal plane and a mounting surface of a blade; the rear tool rod is a hard alloy circular rod made of YG6. A dovetail groove is formed between the front tool rod and the rear tool rod so that the front tool rod and the rear tool rod are assembled together in an interference fit manner. The inclined plane dovetail groove embedded type deep hole precision turning tool has the advantages of simple structure and convenience for installation and detachment; the front tool rod and the rear tool rod are mounted together after the front tool rod is heated; then the tool is detached by using the difference of thermal coefficients of two materials after the tool is heated; the tool is stable to cut in a use process and the stability is good.
