4 Teeth Standard Flat Mills

EHU110-4

Solid carbide 4 flute standard flat knife

Guohong flat knife series is carefully built for high-precision plane machining. The milling cutters are made of high-quality, special grained carbide material, which ensures excellent hardness and rigidity for high cutting forces. The cutting edge is professionally precision ground with a sharp edge and extremely high straightness, which can effectively reduce the cutting resistance and improve the finish of the machined surface.

Tool wear

Failure analysis

The failure mode of the tool is chipping failure

Under the same working conditions, after a certain period of processing, the surface wear of Guohong tool is smaller, the performance is more stable, and the surface finish of the machining is higher.
