This page covers every SNMX 120620 insert we can supply — 8 variants across Achteck, published for Steel, Stainless steel, Cast iron, Heat-resistant alloys. The square 90° geometry gives it 8 cutting edges and makes it suitable for heavy roughing, square shoulders and interrupted cuts.
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 SNMX 120620.

Cutting data
The 8 variants of SNMX 120620 listed here are supplied without a full published cutting-data set, so we do not publish one.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
8 variants of SNMX 120620 are stocked in these grades: AC301K, AP251K, AP351U, AC151K, AC251P.
Across this range the grades specified most often are AC301K, AP251K, AP351U, AC151K, AC251P. 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.
Chipbreaker geometries
Chipbreakers stocked for SNMX 120620: MM4, RR2.
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.
