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.

BB® BK2063 Ball Nose End Mills

The unique diamond coating enables the milling cutter to process harder materials. But at the same time, it should be noted that it is not suitable for soft material machining.

Cutting Parameters

vc=130 (120-180)m/min ap=1/3D(1/8-1/2D)
ae=1/2D(1/4-1D) fz=0.15mm(0.02-0.2)
Please adjust the parameters according to the material and hardness of workpieces.
