LNMX 100512 is a rectangular 90° milling insert with 2 usable cutting edges, used mainly for grooving, parting and shoulder work. We list 13 stock-keeping variants of it from Achteck, covering Steel, Stainless steel, Heat-resistant alloys, Hardened steel.
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 LNMX 100512.
