This page covers every AOMT 120420 insert we can supply — 6 variants across Achteck, published for 钢, 不锈钢, 耐热合金. The 85° parallelogram geometry gives it 2 cutting edges and makes it suitable for copying and fine profiling.
铣削刀片 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 AOMT 120420.

Cutting data
The 6 variants of AOMT 120420 listed here are supplied without a full published cutting-data set, so we do not publish one. Ask us for the specific grade and chipbreaker you are considering and we will send the manufacturer's window for it.
Carbide grades available
6 variants of AOMT 120420 are stocked in these grades: AC451S, AP351S, AP251U, AP351M, AP403M, AP403S.
Across this range the grades specified most often are AC451S, AP351S, AP251U, AP351M, AP403M. Within one brand's range, a higher middle digit usually means a tougher grade — better on interrupted cuts, slightly less wear resistant. See carbide grades explained for how to read the names.
槽型 geometries
断屑槽 stocked for AOMT 120420: MM4.
For milling, the geometry code marks the intended duty — sharper for light cuts and better finish, stronger for scale and interruption. Milling insert selection guide.
