ISO designation structure
What WNMG Means
WNMG identifies a trigon insert shape, no relief angle, tolerance class M, and a cylindrical clamping hole with chipbreaker on both faces.
Geometry Summary
WNMG uses the W-style trigon shape in the ISO code system. This code-level geometry is distinct from the manufacturer's grade and chipbreaker selection.
Documented family example
Kennametal lists WNMG060404MN with ANSI WNMG331MN. This example confirms that a published product record can express the family in ISO and ANSI formats.
Common WNMG Sizes
Specific size mappings beyond the documented product example remain pending in V1. This page does not infer dimensions from a code string.
Grade and Chipbreaker Context
Use the base code to identify geometry, then consult product documentation for a grade and chipbreaker appropriate to the operation.

FAQ
What shape is identified by W in WNMG?
The ISO code-system reference identifies W as a trigon shape.
Does WNMG specify a grade?
No. Grade and chipbreaker selection require the manufacturer's product documentation.
Can I search WNMG codes in V1?
V1 currently returns only the verified CNMG 432 mapping. WNMG size mappings remain pending.
