At CNC Tools Depot, we bring you the largest selection of WNMG carbide inserts from world-renowned brands including Korloy, Widia, Kennametal, Taegutec, Mitsubishi, Sandvik, and more.

WNMG inserts are double-sided, negative-rake, 80° diamond-shaped inserts designed for general-purpose and heavy-duty turning applications. They are highly versatile and deliver exceptional chip control, longer tool life, and excellent surface finish.

🔹 What Does WNMG Mean? (ISO Insert Code Explanation)

• W – Insert Shape: Trigon (80° diamond shape, double-sided)

• N – Clearance Angle: 0° (Negative rake, double-sided cutting edges)

• M – Tolerance Class: Medium (general turning)

• G – Special Features: Chip breaker or geometry for better chip evacuation

This makes WNMG inserts perfect for high-strength machining with efficient material removal.

🔹 Applications of WNMG Inserts

WNMG inserts are widely used in CNC lathes and turning centers for:

• General Turning – Ideal for medium to roughing operations

• Heavy-Duty Cutting – Handles interrupted and continuous cuts efficiently

• Material-Specific Machining

  • Steel (P) – Rough to finish turning with toughness

  • Stainless Steel (M) – Better chip evacuation & wear resistance

  • Cast Iron (K) – High stability for rigid machining

  • Super Alloys & Hardened Materials (S/H) – With advanced coatings

🔹 Types of WNMG Inserts (By Geometry & Chip Breaker)

• WNMG080408 – General turning insert for steel & stainless

• WNMG080412 – Larger depth of cut, strong cutting edge

• WNMG060404 – For fine finishing

• WNMG with Chip Breakers (e.g., WF, PM, MM) – Optimized chip evacuation based on material

• Coatings – TiN, TiCN, Al2O3, CVD, PVD for extended tool life
