Tungaloy TNMG160408-37 NS9530 Turning Insert

Mirror Surface Finishing | -37 Precision Geometry | NS9530 Cermet Grade

How do I achieve a high-gloss mirror finish on steel components?

The Tungaloy TNMG160408-37 NS9530 is a high-performance triangular cermet insert specifically engineered for the high-speed finishing of carbon and alloy steels. Utilizing the NS9530 cermet technology, this insert offers exceptional chemical stability and resistance to oxidation, preventing built-up edge (BUE) and delivering a superior high-luster surface. 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 professional's choice for CNC operations requiring tight dimensional tolerances and aesthetic perfection.

NS9530 Cermet Grade

A titanium-based cermet that excels in finishing. It maintains a sharp edge longer than carbide and produces a higher luster on steel due to its low affinity for the workpiece material.

-37 Finishing Geometry

Designed specifically for light cutting depths. The -37 chipbreaker ensures stable chip evacuation at low feed rates, protecting the workpiece surface from scratches.

0.8mm Strong Radius

The 0.8mm corner radius provides a perfect balance of edge strength and surface finish, allowing for stable machining even in light interrupted finishing passes.

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

Technical Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG160408-37 TNMG 332-37
Inscribed Circle (IC) 9.525 mm 3/8"
Thickness (S) 4.76 mm 3/16"
Corner Radius (RE) 0.8 mm 1/32"

Recommended Finishing Parameters

  • Cutting Speed (Vc): 150 - 380 m/min (Maintain high speed for mirror luster)
  • Feed Rate (f): 0.10 - 0.35 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.
  • Final dimensioning of alloy steel shafts.
  • Automotive components requiring mirror-like surface luster.
  • Boring operations where Ra values under 0.8 are required.

5. Tool 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.
