APMT 1604 is an 85° parallelogram milling insert with 2 usable cutting edges, used mainly for copying and fine profiling. We list 8 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 APMT 1604.
