SDMT 120408 is a square 90° milling insert with 8 usable cutting edges, used mainly for heavy roughing, square shoulders and interrupted cuts. We list 17 stock-keeping variants of it from Achteck, covering 钢, 不锈钢, 铸铁, 耐热合金.

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 SDMT 120408.

Cutting data

The 17 variants of SDMT 120408 listed here are supplied without a full published cutting-data set, so we do not publish one.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

17 variants of SDMT 120408 are stocked in these grades: AP251K, AP251U, AP403M, AC251P, AC151K, AP351M, AC301K, AP351U.

Across this range the grades specified most often are AP251K, AP251U, AP403M, AC251P, AC151K. 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 SDMT 120408: MM4, MR2.

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.
