The characteristics of the single edge left-hand down milling cutter mainly include the following points:

1, high cutting efficiency: Because there is only one cutting edge of the single-edge left-hand down cutting cutter, radial force will not be generated during the cutting process, thereby improving the cutting efficiency.
2, high cutting accuracy: because of the special structure of the single-edge left-turn down milling cutter, the cutting amount of each cutting edge is uniform, so the size of the cut material is more accurate.
3, the cutting force is small: the cutting force of the single-edge left-turn down milling cutter is mainly concentrated on the cutting edge, so the cutting force is small, which can reduce the impact on the machine tool and the tool.
4, a wide range of applications: single-edge left-turn down milling cutter is suitable for the processing of various materials, such as cast iron, steel, etc., and can be used for roughing and finishing.
5, long service life: Because the cutting edge of the single-edge left-turn down milling cutter uses special materials and heat treatment process, its service life is long.

To sum up, the single-edge left-hand downcut milling cutter has the advantages of high efficiency, high precision and low cost, so it has been widely used in the machining industry.
