Non-ferrous metal deep hole processing tool

The utility model relates to a non-ferrous metal deep hole processing tool. The problem of non-ferrous metal deep hole processing is solved. The non-ferrous metal deep hole processing tool comprises a knife handle, a guide cone used for guiding the tool and reducing the friction between the tool and the hole wall, a fine polishing tooth used for circular surface correcting and processing after an end tooth is cut and the end tooth used for part cutting. The length L3 of the fine polishing tooth is 0.8-1.0 time of the diameter theta of the end tooth. The length L2 of the guide cone is 10-12.5 times of the length L3 of the fine polishing tooth. According to the non-ferrous metal deep hole pressing tool, the phenomenon that in an ordinary tool an inverted cone hole with a big opening and small lower face is easy to occur can be avoided, the cylindrical requirement of a processing hole is effectively guaranteed, and meanwhile the size tolerance and the surface roughness can be well guaranteed.
