Seco Tools has introduced two new PCD-tipped milling insert grades, the PCD05 and PCD20, for use with its Turbo 10 cutters. Designed for aerospace and automotive part production, these grades produce good surface quality in finish machining applications involving aluminum and titanium-alloy workpiece materials. The grades are also effective in cutting polymers and fiber-reinforced composites, the company says.

The grades come in the company’s X010 insert size with a corner radius of 0.016" (0.4 mm) and wiper length of 0.43" (1.08 mm). The Turbo 10 cutter bodies that hold the PCD05 and PCD20 include precision-milled pocket seats that improve run-out, stability and tool life by providing optimal contact between the tool body and insert. Integrated through-coolant channels support high productivity and promote excellent chip evacuation.

The PCD05 and PCD20 milling insert grades work alone or alongside carbide inserts in the same Turbo 10 cutter body. When used with carbide inserts, the PCD insert grades serve as wiper inserts in fixed pockets. Conversely, running the PCD05 and PCD20 in one Turbo 10 cutter body optimizes their potential and ensures maximum cutting parameters, the company says.
