Solid-Carbide Cutter for Milling Aluminum

For aerospace manufacturing, the MC166 Advance is developed for finishing and dynamic roughing of deep pockets and cavities.

WALTER USA unveiled its MC166 Advance solid-carbide milling cutter, developed for aerospace manufacturing and well-suited to machining aluminum, copper, brass, bronze, and magnesium-based alloys (ISO N workpiece group).

The tool was specifically designed for finishing and dynamic roughing of deep pockets and cavities. Dynamic milling involves machining at a low radial depth of cut (ae), a high axial depth of cut (ap) and with a large cutting-edge length (Lc), which is three times the cutting-edge diameter (Dc) for the MC166 Advance.

The MC166 Advance solid-carbide milling cutter – with increased core stability compared to a conventional tool core – ensures a consistently reliable machining process even in unattended operations. A differential pitch provides optimum operational smoothness and significantly extends tool life.

The cutter’s special micro-geometry makes it an ideal choice for finishing high-wall part features. The tool provides a high level of productivity and reduces cycle times because of its ability to mill at an optimal metal removal rate. The tool also features a 35° helix and a DIN 6535 HA (round cylindrical) shank. The uncoated WJ30UU-grade cutter is available in diameters from 12 to 20 mm.
