BB End Mill-3F BF2045 BF2055

BB® 3 Flutes Solid Carbide End Mills

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid tool-holding systems.
Design:Negative front angle and large chip space.Easier roughing and finishing processing. Decreasing the times of changing cutters,Saving production time.

Application

BB 3 flutes end mills is used on aluminum and copper processing, provide effectively mitigate vibration and stable cutting.
Use a higher rake, sharp edge and oil (MQL) mist to decrease cutting load and built-up edge
