Zhuzhou Century Tool WNMG Turning Inserts are designed for high-efficiency CNC turning applications where productivity, cost control, and machining stability are critical.
Featuring A-GEO™ Adaptive Geometry Technology, Century WNMG inserts provide stable chip control, reduced cutting resistance, and reliable cutting performance under real production conditions.
With a strong double-sided triangular design, optimized edge preparation, and advanced carbide grades, WNMG inserts deliver excellent performance for steel turning, alloy steel machining, stainless steel applications, and general manufacturing.
WNMG inserts are one of the most widely used negative rake carbide inserts for CNC turning.
The WNMG designation represents:
| Code | Meaning |
|---|---|
| W | 80° Trigon Shape |
| N | 0° Clearance Angle |
| M | Standard Tolerance |
| G | Hole and Chip Groove Design |
WNMG inserts feature a double-sided 80° triangular geometry, providing multiple cutting edges and excellent cost efficiency.
Compared with CNMG inserts, WNMG inserts offer:
Many standard turning inserts are developed under ideal machining conditions.
However, real manufacturing environments often include:
Century A-GEO™ technology is optimized for these real production challenges.
Advanced chip breaker design helps maintain stable chip formation under different:
Benefits:
✔ Reduced chip entanglement
✔ Better automation performance
✔ More stable unmanned machining
Optimized rake geometry improves chip flow and reduces cutting pressure.
Benefits:
WNMG inserts provide multiple cutting edges from a single insert.

Century WNMG inserts are designed for manufacturers who need:
✔ Stable machining
✔ Lower tooling cost
✔ Reliable chip control
✔ Longer production cycles
✔ Consistent surface finish
WNMG inserts are widely used in:
WNMG inserts are mainly used for external turning, facing, and general CNC machining operations where productivity and cost efficiency are important.
WNMG inserts use a triangular geometry with multiple cutting edges, making them economical for production machining. CNMG inserts provide stronger edges and are better suited for heavier cutting conditions.
Yes. With the correct carbide grade and chip breaker, WNMG inserts are widely used for carbon steel, alloy steel, and general engineering materials.
For 42CrMo machining, WNMG080408 with A-GEO™ Universal geometry and CT2525 grade is recommended for general turning applications.
