Tungaloy TNMG160404-TM T9115 Turning Insert

High-Speed CVD Grade | TM Medium-Cutting Chipbreaker | Premium Steel Machining

What is the best carbide insert for high-speed steel turning?

The Tungaloy TNMG160404-TM T9115 is a high-performance, double-sided triangular carbide insert optimized for the P-group (Steel) machining spectrum. Utilizing Tungaloy’s advanced T9115 CVD coating technology, this insert provides exceptional wear resistance and plastic deformation resistance during high-velocity operations. The -TM chipbreaker is a versatile medium-cutting geometry that ensures stable chip evacuation across varied depths of cut. 100% Made in Japan, it is engineered for professional CNC shops requiring high productivity and consistent tool life.

T9115 CVD Grade

Specifically designed for steel. Features a thick Al2O3 layer for superior heat protection and a hard TiCN layer for crater wear resistance at high speeds.

TM Chipbreaker Geometry

The "General Purpose" leader for medium cutting. It balances cutting edge strength with lower cutting force to prevent vibration in long-workpiece turning.

Premium Surface Luster

The specialized coating treatment reduces friction between the chip and the rake face, resulting in a superior surface finish on the final part.

Feedback from Global Workshops

⭐⭐⭐⭐⭐ "High Speed Master" - James K., USA
"T9115 is incredibly stable at high RPMs. We cut our cycle times by 15% since switching from a generic P-grade."

⭐⭐⭐⭐⭐ "Original Packaging" - Markus D., Germany
"Authentic Tungaloy Japan stock. The -TM chipbreaker works well for general carbon steel shafts. Quick shipping to Munich."

⭐⭐⭐⭐ "Great for Mass Production" - Hiroshi S., Japan
"Consistent tool life. We run these on our Nakamura lathes for 24/7 production with very few offsets needed."

⭐⭐⭐⭐⭐ "Best Price for Original" - Carlos M., Mexico
"Beyond is a reliable B2B partner. These inserts are genuine and help us stay competitive in automotive part supply."

⭐⭐⭐⭐⭐ "Reliable TM Geometry" - Alistair M., UK
"No chip wrapping issues on 4140 steel. The 0.4mm radius gives a very clean finish for final dimensioning."

8. FAQ - CNC Machine Support

Q: Can I use T9115 for machining stainless steel?

A: While it can handle light stainless cuts, T9115 is optimized for Steel (P). For stainless, we recommend the T6130 grade which is specifically designed to handle heat and work-hardening.

Q: Is the 0.4mm corner radius strong enough for heavy roughing?

A: The 0.4mm radius is better for medium-to-finishing. For heavy roughing with scale or interrupted cuts, we recommend a 0.8mm or 1.2mm radius for better edge integrity.

Q: What is the difference between TM and TS chipbreakers?

A: -TM is a general-purpose medium-cutting geometry. -TS is a finishing chipbreaker with a sharper edge designed for lighter depths of cut and lower feed rates.

Tech Tip: CVD Coating for Steel

The **T9115 CVD grade** is engineered for high-temperature stability. In high-speed turning, the Al2O3 layer prevents heat from reaching the carbide substrate, preventing deformation. Maintain high Vc for optimal results. **Tungaloy Japan** - Global Tooling Excellence.

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.
