Extreme Profiling Clearance

The slim 35° profile allows for machining into tight corners and deep recesses that other geometries cannot reach.

Negative 4-Edge Design

Unlike positive V-style inserts, the negative VN series offers double the edges, significantly lowering your tool cost-per-part.

Superior Surface Finish

Tungaloy's ground peripheries and precision-molded chipbreakers minimize chatter in light finishing passes.

Machining Data Recommendations

Compatible with MVJNR/L, MVVNN, and DVJNR/L Tool Holders

Typical Applications

• Precision external profiling of complex shafts.
• Machining of narrow V-grooves and undercuts.
• Finishing passes on automotive and aerospace turbine parts.
• Profiling components with strict surface finish requirements.

Machine Compatibility

Seamlessly integrates with Haas, Mazak, Doosan, and Star Swiss-Type Lathes. Best suited for machines with high-precision spindle control and multi-axis capability.

⭐⭐⭐⭐⭐ "Profiling Genius" - R. Miller, USA
"We run VNMG for our tight-radius shaft work. The AH725 grade is the only thing that doesn't chip in the narrow undercuts."

⭐⭐⭐⭐⭐ "Stable and Precise" - H. Sato, Japan
"Tungaloy VN inserts provided the dimensional stability we needed for a large aerospace contract. Excellent surface finish."

⭐⭐⭐⭐ "Great Economy" - D. Schmidt, Germany
"Switching from positive VCGT to negative VNMG saved us huge on edge costs. BEYOND CNC delivers fast."
