LNET 1206 is a rectangular 90° milling insert with 2 usable cutting edges, used mainly for grooving, parting and shoulder work. 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 LNET 1206.
