BB® Solid Carbide Ball Nose 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.
Tolerance of End Mill Diameter:
1 < D≤6 -0.010 ~ -0.030
6 < D≤10 -0.015 ~ -0.040 10 < D≤ 20 -0.020~-0.050
Double-edge design improves rigidity and surface finish effectively. Cutting edge over the center reduces the cutting resistance. High capacity of junk slot benefits chip removal and increases machining efficiency. 2 flutes design is good for chip removal, easy for vertical feed processing, widely used in slot, profile, and hole processing.
