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.
