Tungaloy TNMG160402-11 NS9530 Turning Insert

Ultra-Precision Finishing | NS9530 Cermet Grade | 0.2mm Corner Radius

What is the best cermet insert for high-gloss steel finishing?

The Tungaloy TNMG160402-11 NS9530 is a specialized precision turning insert designed for light finishing operations on carbon and alloy steels. Utilizing the NS9530 premium cermet grade, this insert provides exceptional chemical stability and resistance to oxidation at high cutting temperatures. The 0.2mm corner radius (02) combined with the -11 chipbreaker allows for extreme dimensional accuracy and a mirror-like surface finish. 100% Made in Japan, it is the industrial benchmark for high-speed finish turning.

NS9530 Cermet Grade

A titanium-based cermet that offers superior fracture toughness and surface finish. Its low affinity for steel prevents built-up edge (BUE), maintaining a clean cut.

-11 Chipbreaker

Specifically designed for finishing to light-duty cutting. It ensures excellent chip control at small depths of cut, preventing long, stringy chips from scratching the workpiece.

Ultra-Sharp 0.2mm Edge

The small 0.2mm radius reduces cutting pressure and is perfect for thin-walled parts or applications requiring sharp internal corners and fine Ra values.

3. Technical Data: Metric vs. Imperial Comparison

Feature Metric (ISO) Imperial (ANSI)
Standard Model TNMG160402-11 TNMG 330.5-11
Inscribed Circle 9.525 mm 3/8"
Thickness 4.76 mm 3/16"
Corner Radius 0.2 mm 1/128"

Recommended Cutting Parameters

  • Cutting Speed (Vc): 150 - 380 m/min (Maintain high speed for mirror gloss)
  • Feed Rate (f): 0.05 - 0.20 mm/rev (Optimize for 0.2mm radius)
  • Depth of Cut (ap): 0.1 - 1.2 mm

*Pro-Tip: Cermet works best in dry finishing at high speeds. High Vc levels activate the titanium cermet luster effect on steel.*

4. Primary Applications

  • High-speed finishing of carbon and alloy steels.
  • Final passes on precision shafts and automotive valves.
  • Boring small diameters where space is limited.
  • Operations requiring low cutting forces to prevent part deflection.

5. Tool Compatibility

Fits standard TN** 1604 triangular pockets. Pairs perfectly with MTJNR/L or WTJNR/L holders. Recommended for S-WTJNR boring bars for internal finishing.

Professional Machinist Feedback

⭐⭐⭐⭐⭐ "Mirror Finish Success" - James W., USA
"Using the 0.2mm radius for light finishing on 4140 steel. The Ra values are better than anything I've used before. Genuine Tungaloy quality."

⭐⭐⭐⭐⭐ "Excellent Luster" - Heinrich G., Germany
"NS9530 is my favorite for finishing. The luster on the workpiece is perfect. Beyond delivered these fast and they are 100% original Japan parts."

⭐⭐⭐⭐ "Great for Thin Parts" - K. Saito, Japan
"The low cutting force of the 0.2mm radius is perfect for my thin-walled parts. Chip control is very reliable."

⭐⭐⭐⭐⭐ "Authentic and Fast" - Carlos P., Italy
"Factory sealed box. The -11 chipbreaker works exactly as described. Reliable source for B2B."

⭐⭐⭐⭐⭐ "Consistent Accuracy" - Arjun S., India
"Held tolerances within 0.01mm over a large batch. The cermet grade keeps its edge remarkably well."

8. FAQ - Machine Shop Support

Q: Is a 0.2mm radius more fragile than a 0.4mm?

A: Yes, it is more delicate. It should only be used for finishing passes with light depths of cut. Avoid heavy roughing or interrupted cuts.

Q: Can I use NS9530 on stainless steel?

A: While it can be used for very light finishing on some stainless grades, it is specifically optimized for carbon and alloy steels (P group materials).

Tech Tip: Achieving Mirror Finishes

To get the best result from **NS9530**, use high cutting speeds (Vc > 250 m/min) and ensure your machine has high spindle stability. The 0.2mm radius is the secret to perfect surface luster. **Tungaloy Japan** - Excellence in 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.
