WNMG is the 80° trigon turning insert: the strength of an 80° corner, with three corners per side on a double-sided insert, so each one gives you six cutting corners. W is the trigon shape, N means 0° relief (a negative insert), M is the tolerance class, and G means a center hole with chip breakers on both sides.
ISO and ANSI codes name the same insert: WNMG 080408 is WNMG 432, and 060408 is 332.
