APKT 1003 is an 85° parallelogram milling insert with 2 usable cutting edges, used mainly for copying and fine profiling. We list 3 stock-keeping variants of it from Achteck, covering Steel, Stainless steel, 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 APKT 1003.
