Tungaloy TNMG160404-37 NS9530 Turning Insert

High-Speed Surface Gloss | -37 Precision Chipbreaker | NS9530 Cermet Technology

How do I achieve a mirror-like surface on steel parts efficiently?

The Tungaloy TNMG160404-37 NS9530 is a high-performance triangular cermet insert specifically engineered for the high-speed finishing of carbon and alloy steels. Built with the NS9530 cermet grade, this tool offers exceptional chemical resistance and thermal stability, preventing built-up edge (BUE) and delivering a superior high-gloss finish. The -37 chipbreaker is specialized for light-duty finishing, providing excellent chip control at shallow depths of cut. 100% Made in Japan, it is the industrial standard for precision CNC turning operations requiring tight tolerances and aesthetic perfection.

NS9530 Cermet Grade

Titanium-based cermet with high fracture toughness. It maintains a sharp edge far longer than carbide in finishing applications, ensuring dimensional stability across large batches.

-37 Precision Chipbreaker

Designed for finishing to light cutting. Its geometry breaks chips reliably at low feed rates, preventing workpiece scratching and "birds-nesting" during automated cycles.

High Fracture Toughness

Unlike brittle cermets, NS9530 is engineered for resilience, making it capable of handling light interrupted cuts without edge chipping.

3. Technical Specifications: Metric (ISO) vs. Imperial (ANSI)

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG160404-37 TNMG 331-37
Inscribed Circle (IC) 9.525 mm 3/8"
Thickness (S) 4.76 mm 3/16"
Corner Radius (RE) 0.4 mm 1/64"

Recommended Finishing Parameters

  • Cutting Speed (Vc): 150 - 380 m/min (Maintain high speed for mirror luster)
  • Feed Rate (f): 0.05 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro-Tip: Cermet performs best in dry cutting conditions. High surface speeds are essential to activate the "burnishing" effect of the NS9530 grade.*

4. Primary Applications

  • High-precision finish turning of carbon steels (e.g., 1045).
  • Final dimensioning of alloy steel components.
  • Automotive shafts and valves requiring ultra-smooth Ra values.
  • Boring operations where high gloss is required.

5. Equipment Compatibility

Standard fit for TN** 1604 triangular pockets. Fully compatible with MTJNR/L, WTJNR/L, and DTGNR/L holders. Perfect for CNC lathes with high spindle speeds.

Reviews from Professional Machine Shops

⭐⭐⭐⭐⭐ "Mirror Finish on 4140 Steel" - Markus H., Germany
"Using the -37 chipbreaker on alloy steel finishing passes. The Ra value is incredible. The luster looks like it was polished. Beyond provided fast shipping."

⭐⭐⭐⭐⭐ "Consistent and Sharp" - James K., USA
"Original Tungaloy stock. Switched to NS9530 for our automotive shafts. Dimensional stability is much better than our previous carbide inserts."

⭐⭐⭐⭐ "Great Chip Control" - Alessandro R., Italy
"Handles low feeds perfectly. No more 'bird-nest' chips wrapping around the spindle. High-quality cermet."

⭐⭐⭐⭐⭐ "Authentic Japan Quality" - S. Nakamura, Japan
"Factory sealed box. The -37 geometry is very sharp. Excellent for final finishing on CNC lathes."

⭐⭐⭐⭐⭐ "Best B2B Price" - Rajesh V., India
"Reliable supplier for our workshop. The technical specs were accurate and the performance is top-tier."

8. FAQ - Professional Support

Q: Why choose cermet over coated carbide for finishing?

A: Cermet (NS9530) has a much lower chemical affinity for steel, which means it doesn't "stick" to the metal. This results in a significantly higher gloss finish and less edge wear.

Q: Is the -37 chipbreaker suitable for heavy roughing?

A: No. The -37 chipbreaker is specifically designed for finishing and light cutting. For roughing, we recommend the -38 or -33 geometries in carbide grades.

Tech Tip: Achieving High Surface Gloss

To maximize the performance of **NS9530**, use dry cutting for the final pass. This allows the cermet's thermal properties to burnish the steel surface. **Tungaloy Japan** - Excellence in precision surface technology.

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.
