Tungaloy TNMG160408R-S T6130 Turning Insert
Professional Right-Hand Stainless Machining | T6130 Premium Grade | RS Finishing Geometry
What is the most reliable right-hand insert for finishing 304/316 stainless?
The Tungaloy TNMG160408R-S T6130 is an industrial-grade turning insert specifically engineered to overcome the high-heat and work-hardening challenges of stainless steel. Featuring the advanced T6130 CVD coated carbide grade, it provides a perfect balance of wear resistance and toughness. The -S (RS) chipbreaker is specialized for light-duty finishing to semi-finishing, offering sharp cutting edges that minimize vibration. Designed for Right-Hand (R) tool paths with a strong 0.8mm radius, this insert ensures superior surface integrity and dimensional accuracy. 100% Made in Japan, it is the standard for B2B precision manufacturing.
T6130 CVD Technology
A dedicated grade for M-group materials. The smooth surface coating prevents Built-Up Edge (BUE) and significantly reduces thermal cracking in interrupted stainless cuts.
RS (-S) Finishing Chipbreaker
Engineered with a sharp rake angle to slice through tough stainless fibers. It manages chips effectively at lower feeds, ensuring a mirror-like finish.
0.8mm Stable Edge
The 0.8mm corner radius offers increased edge strength over smaller variants, allowing for slightly higher feed rates without sacrificing surface quality.

Recommended Finishing Parameters (Stainless)
-
Cutting Speed (Vc): 80 - 180 m/min
-
Feed Rate (f): 0.10 - 0.35 mm/rev
-
Depth of Cut (ap): 0.2 - 2.0 mm
*Pro-Tip: High feed rates with stainless steel help avoid surface hardening. Always use high-pressure coolant to prolong T6130 grade life.*
4. Primary Applications
- Austenitic Stainless (304, 316, 316L).
- Duplex and Super Duplex machining.
- Final dimensioning of food-grade machinery parts.
- Automotive components requiring precision R-hand finishing.
5. Tool Compatibility
Fits all standard ISO/ANSI TNMG 1604 pockets. Optimized for Right-Hand (RH) holders like MTJNR, WTJNR, or DTGNR. Compatible with DMG Mori, Mazak, Haas, and Okuma CNC machines.

Global Shop Feedback
⭐⭐⭐⭐⭐ "Stainless Steel Solution" - David R., USA
"T6130 is the only grade that consistently stops BUE for us. The 0.8mm radius is strong enough for our rougher finishing passes."
⭐⭐⭐⭐⭐ "Perfect Finish" - Markus D., Germany
"Authentic Tungaloy. The -S chipbreaker manages finishing chips perfectly on 316 stainless. No bird-nesting issues."
⭐⭐⭐⭐ "Very Reliable" - H. Sato, Japan
"Consistent wear pattern. We use these for precision valves and the results are predictable every time."
⭐⭐⭐⭐⭐ "Fast Shipping" - Carlos M., Mexico
"Beyond always provides original stock. Arrived fast and the technical advice helped us optimize our spindle speed."
⭐⭐⭐⭐⭐ "Great for 304" - Alistair M., UK
"High luster surface finish. Best price for genuine Tungaloy in the UK."
8. FAQ - Technical Support
Q: Why choose T6130 over the T9125 grade for stainless?
A: T6130 is specifically designed for M-group materials (Stainless Steel). It handles the gummy nature of stainless and prevents built-up edge much more effectively than general steel grades.
Q: Can I use this for light roughing?
A: With the 0.8mm radius, it can handle light semi-roughing, but the -S (RS) chipbreaker is specifically optimized for finishing. For heavy roughing, we recommend the -TM or -TH geometries.
Q: What tool holder fits this insert?
A: Any standard ISO 1604 series holder. For the R-hand orientation, use holders like MTJNR 2525 M16.
Tech Tip: Managing Stainless Steel Heat
Stainless steel has low thermal conductivity. The **T6130 grade** is engineered to act as a heat shield, protecting the carbide edge. Maintain high speed to ensure heat is carried away in the chip. **Tungaloy Japan** - Engineering excellence for global industry.
