BB® Tungsten Steel 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. Dementions 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 Industrial Design Negative front angle and large chip space.Easier roughing and finishing processing. Decreasing the times of changing cutters,Saving production time. Helix Angle:35 deg, high adaptability to the material and hardness of workpieces, widely used to mold and product processing and cost efficient. Coating:Good coating can improve tools life and production efficiency, as well as solve the cutting problems. Application Used in Milling Machine.,CNC,Drill press,Engraving machine. Metal, woodworking, alloy steel, stainless steel, etc BB 2 flutes end mills is widely used in slotting, sinking etc. 3 flutes for aluminum，non-ferrous metal. 4 flutes, high rigidity, widely used in shallow slot, profile milling, and finish machining.
