WNGU 040308 is an 80° trigon milling insert with 6 usable cutting edges, used mainly for profiling that also needs to take a decent depth of cut. We list 4 stock-keeping variants of it from Achteck, covering Steel, Stainless steel, Cast iron, Heat-resistant alloys.
Milling inserts are chosen to match the cutter body — lead angle, number of teeth and the geometry designated by the manufacturer. The milling insert selection guide walks through that; this page lists what we actually hold in WNGU 040308.
