This Mitsubishi Materials DIAEDGE WNMG080404-MK (ANSI WNMG431MK) is a negative-rake, 80-degree trigon turning insert in MC5005 carbide grade, supplied as a new box of 10 inserts made in Japan. The designation decodes to an 80-degree trigon shape, 0-degree clearance, M tolerance, and a cylindrical hole with chipbreakers, with a 1/2 in inscribed circle, 4.76 mm (3/16 in) thickness, and 0.4 mm (1/64 in) nose radius. The MK chipbreaker is intended for medium-cut turning. The box label rates the grade for ISO P (steel) at 185-415 m/min (605-1360 SFM) and ISO K (cast iron) at 215-345 m/min (705-1130 SFM), with a feed range of 0.14-0.28 mm/rev (0.006-0.011 IPR). The insert fits holders that accept WNMG-style negative inserts of this size, such as MWLN-type external turning holders.
