Cutting data
The 25 variants of SNMX 120612 listed here are supplied without a full published cutting-data set, so we do not publish one.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
25 variants of SNMX 120612 are stocked in these grades: AC301K, AP251K, AP351U, AP251U, AP403M, AC151K, AC251P.
Across this range the grades specified most often are AC301K, AP251K, AP351U, AP251U, 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.
