Tungaloy Negative Turning Inserts Collection

Maximum Edge Strength | Double-Sided Economy | High-Production Roughing

Which negative insert offers the highest cost-efficiency for high-volume steel removal?

The Tungaloy Negative Turning Insert series is the industry benchmark for high-rigidity CNC machining. Designed with a 0° relief angle, these double-sided inserts (such as CNMG, DNMG, and WNMG) provide twice the cutting edges compared to positive inserts, significantly lowering your cost-per-edge. Featuring the revolutionary PremiumTec surface technology and T9200 CVD series, these tools are built to withstand the extreme thermal loads of heavy roughing in Steel (P) and Cast Iron (K). The robust edge design ensures stability during interrupted cuts, while the specialized -TM and -TH chipbreakers provide superior chip control even at high feed rates.

Double-Sided Edge Life

Negative geometry allows for cutting edges on both the top and bottom of the insert, maximizing your tooling budget and reducing downtime.

T9200 CVD Coating

A thick Alumina (Al2O3) layer provides incredible crater wear resistance, enabling higher cutting speeds (Vc) in high-volume production.

Robust Chipbreakers

The -TM breaker is optimized for semi-finishing to medium cutting, while the -TH is built for heavy interrupted roughing.

Global Industry Reports

⭐⭐⭐⭐⭐ "Bulldozer in Steel" - Robert T., USA
"The T9215 WNMG inserts are a game changer for our shaft production. We increased feed by 20% and the edges still look fresh after 50 parts."

⭐⭐⭐⭐⭐ "Consistent Performance" - Klaus M., Germany
"Tungaloy's negative inserts provide the stability we need for our automated cells. Beyond CNC's fulfillment is reliable and fast."

⭐⭐⭐⭐ "Great Economy" - S. Rossi, Italy
"Switched from positive to negative for our roughing operations. The 6 edges on the WNMG saved us a fortune this quarter."

Technical FAQ

Q: Can I use negative inserts on a light-duty lathe?

A: Negative inserts require more horsepower and rigidity. For hobbyist or light-duty machines, positive inserts are usually preferred to prevent stalling or deflection.

Q: What is the benefit of a WNMG over a CNMG?

A: WNMG (Trigon) offers 6 cutting edges compared to CNMG's 4, providing better cost-efficiency for 80° turning applications while maintaining similar strength.

Q: Is T9225 good for interrupted cuts?

A: Yes. T9225 is Tungaloy's most versatile grade for steel, featuring a balanced substrate that handles thermal shock and mechanical impact very well.

Pro Machinist Tip: Tool Pressure

Because **Negative Inserts** generate more radial force, ensure your workpiece is properly supported with a tailstock for any length-to-diameter ratio over 3:1. **BEYOND CNC** - Your Partner in Power.
