Tungaloy VNMG160408-TM T9115 Turning Insert

High-Performance Steel Machining | CVD Coated PremiumTec Grade

Which insert offers the best reliability for high-speed steel profiling and medium cutting?

The Tungaloy VNMG160408-TM T9115 is a powerhouse for steel turning. Featuring the T9115 grade, which utilizes Tungaloy's proprietary PremiumTec surface technology, this insert is designed to withstand the extreme temperatures of high-speed machining. The -TM (Medium Cutting) chipbreaker provides a balanced geometry that excels in profiling and general turning, ensuring excellent chip evacuation even in varying depths of cut. Its 35° rhombic shape allows for maximum clearance, making it indispensable for complex workpiece contours where tool interference is a risk.

T9115 CVD Coating

Multi-layered coating with exceptional adhesion and hardness. Perfect for stable, high-speed turning of general steels (P10-P25).

-TM Chipbreaker

Engineered for medium-duty cutting. It provides a wide range of chip control, from semi-finishing to light roughing operations.

High Clearance Geometry

The 35° profile offers the clearance needed for profiling steep angles and deep recesses without holder collision.

Industrial User Reports

⭐⭐⭐⭐⭐ "Reliable for Batch Production" - Mark H., USA
"The T9115 grade is my go-to for 1045 steel. Tool life is very predictable, which is essential for our automated shifts."

⭐⭐⭐⭐⭐ "Great Chip Breaking" - Luca M., Italy
"The -TM chipbreaker works exactly as described. No more bird-nesting on our profiling passes. Excellent service from Beyond."

⭐⭐⭐⭐ "Consistent Quality" - Dieter S., Germany
"Fast delivery to Europe. The VNMG 332-TM is a stable performer in alloy steel. Satisfied with the price/quality ratio."

Technical FAQ

Q: What is the benefit of the T9115 PremiumTec coating?

A: PremiumTec enhances the surface smoothness and coating adhesion, significantly reducing friction and crater wear during high-speed steel turning.

Q: Can I use VNMG 160408-TM for finishing?

A: While -TM is a medium-cutting geometry, it can handle semi-finishing. However, for a mirror finish, a -TS or -ZF chipbreaker with a smaller radius (0.4mm) is recommended.

Industrial Tip: Coating Maintenance

To maximize the life of **CVD coated inserts** like the **T9115**, avoid low cutting speeds that lead to built-up edge (BUE). Maintain high speeds to allow the coating to operate in its optimal thermal range. **BEYOND CNC** - Excellence in Industrial Tooling.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
