Is WNMG-UM the same as WNMG-MU?
UM and MU are distinct manufacturer geometry designations. Retain the complete catalog designation when ordering or replacing an insert; do not choose an alternative solely because the size and corner radius match.
What identifies my replacement insert?
Provide the material number, complete WNMG designation, grade and quantity. If you also need a holder or service component, add its exact article as a separate quote line.
