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.

⭐⭐⭐⭐⭐ "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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?
