Tungaloy TNMG160404R-S T6130 Turning Insert
Precision Right-Hand Stainless Steel Machining | T6130 CVD Grade | -S Finishing Geometry
What is the best right-hand insert for finishing stainless steel?
The Tungaloy TNMG160404R-S T6130 is a specialized, industrial-grade turning insert specifically engineered for the challenges of machining stainless steel. Utilizing the advanced T6130 CVD coated carbide grade, it offers exceptional resistance to built-up edge (BUE) and thermal cracking. The -S (RS) chipbreaker provides a sharp cutting edge and optimal chip control for light-duty finishing passes, ensuring a high-quality surface luster on right-hand (R) tool paths. 100% Made in Japan, this tool is the professional benchmark for B2B precision engineering.
T6130 CVD Grade
Optimized for stainless steel (M-group). It features a smooth coating surface that minimizes friction and prevents workpiece material from welding to the cutting edge.
-S (RS) Finishing Geometry
A sharp, high-performance geometry that reduces cutting forces. Perfect for vibration-prone finishing cycles and achieving tight dimensional tolerances.
Right-Hand (R) Design
Specifically designed for right-hand tool holder configurations, directing chip flow away from the finished surface to maintain integrity.

Recommended Finishing Parameters (Stainless Steel)
-
Cutting Speed (Vc): 80 - 180 m/min
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro-Tip: When machining stainless, ensure a constant feed to prevent work-hardening. T6130 grade thrives with high-pressure coolant to manage heat.*
4. Primary Applications
- Precision finishing of Austenitic and Duplex stainless steel.
- Automotive and medical component turning.
- Operations requiring low vibration and high surface luster.
- Continuous turning of heat-resistant alloys.
5. Tool Compatibility
Compatible with standard ISO/ANSI TNMG 1604 pockets. Fits Right-Hand (RH) tool holders such as MTJNR, WTJNR, or DTGNR. Fully compatible with Haas, Mori Seiki, and Mazak lathes.

8. FAQ - Machine Shop Support
Q: Why use T6130 grade for stainless steel instead of T9125?
A: T6130 is specifically formulated for M-group materials. It has specialized thermal properties to handle the work-hardening nature of stainless steel where T9125 might fail prematurely.
Q: Is the 0.4mm radius suitable for roughing?
A: No. The 0.4mm radius and -S geometry are optimized for high-precision finishing. For roughing stainless, we recommend a 0.8mm or 1.2mm radius with a -TM geometry.
Q: How do I identify a Right-Hand (R) insert?
A: The 'R' in the model signifies the cutting direction. When looking at the tool holder from the top, a right-hand tool cuts from right to left toward the spindle.
Tech Tip: CVD Coating for Stainless Steel
To maximize tool life with **T6130**, maintain a consistent cutting speed. The CVD coating is designed to act as a thermal barrier between the high-heat chip and the carbide substrate. **Tungaloy Japan** - Excellence in industrial turning.
