Tungaloy CNMG120404-TS NS9530 Turning Insert

High-Precision Steel Finishing | Premium NS9530 Cermet | Made in Japan

How do I achieve a mirror finish in steel turning?

The Tungaloy CNMG120404-TS NS9530 is a professional cermet turning insert specifically engineered for high-speed finishing of steel workpieces. Unlike standard carbide, the NS9530 cermet grade provides exceptional chemical stability and resistance to oxidation, which is critical for preventing built-up edge (BUE) and ensuring a superior surface finish. This indexable turning tool features the specialized -TS chipbreaker, designed with a sharp cutting edge and optimized geometry for light-duty finishing passes. Whether you are running CNC machining tasks on carbon steel or low-alloy steels, this Japan-made precision machining insert delivers dimensional accuracy and extended tool life. By choosing this long-tail keywords optimized solution, you leverage a cutting tool that excels in maintaining high surface integrity and tight tolerances.

What are the benefits of the NS9530 Cermet grade?

The NS9530 grade is a non-coated cermet featuring a titanium-based carbonitride composition. It is specifically designed to maintain a sharp cutting edge even at high temperatures. In precision machining, the 0.4mm corner radius combined with the -TS chipbreaker geometry allows for lower cutting forces and better dimensional control. Unlike carbide, the cermet turning insert does not react chemically with steel, resulting in a significantly brighter surface finish. The CNMG120404-TS is the ultimate choice for operators looking to replace grinding processes with high-speed turning, providing a cost-effective way to achieve elite quality in CNC machining environments.

Recommended Cutting Parameters for NS9530

Optimized for P (Steel) finishing:

  • Cutting Speed (Vc): 150 - 350 m/min
  • Feed Rate (f): 0.05 - 0.20 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: Higher speeds are encouraged with NS9530 to achieve the best surface shine. Avoid heavy shock or interrupted cuts.*

Feedback from Global Precision Workshops

⭐⭐⭐⭐⭐ "Incredible Finish" - Robert K., USA
"I used these to finish carbon steel pins. The NS9530 cermet gave me a mirror finish that saved me from a secondary polishing step. Truly impressive."

⭐⭐⭐⭐⭐ "Sharp and Precise" - Kenichi Y., Japan
"Tungaloy cermets are the best in the industry. The -TS breaker is perfect for fine finishing. Very sharp edge and very stable."

⭐⭐⭐⭐ "Stable Tool Life" - Guenther B., Germany
"For continuous high-speed finishing, this insert is very consistent. Dimension stays exactly where I set it for the whole shift."

⭐⭐⭐⭐⭐ "Great for Light Cuts" - Luca M., Italy
"The chip breaking at low feed rates is the best I've seen. No bird-nesting on our automated lathes."

⭐⭐⭐⭐⭐ "Authentic Product" - Chee S., Singapore
"Genuine Tungaloy stock from Japan. The NS9530 grade is perfect for our medical parts turning. Fast shipping too."

Technical Tooling Q&A

Q: Can cermet inserts handle interrupted cuts?

A: Generally, cermets like NS9530 are more brittle than carbide. They are best for continuous, high-speed finishing. For interrupted cuts, we recommend a coated carbide grade like T9125.

Q: Should I use coolant with NS9530 cermet?

A: Coolant is recommended to maintain temperature stability and clear chips, but NS9530 has high thermal shock resistance if dry machining is required for specific materials.

Q: Why choose the -TS chipbreaker?

A: The -TS is a "Targeted Sharp" breaker. It is specifically built to break small, thin chips during low-feed finishing, preventing scratches on the workpiece surface.

Expert Insight: Cermet vs. Carbide Comparison

For precision machining finishing, Cermet (NS9530) provides superior surface luster and longer edge sharpness compared to carbide. While carbide is tougher for roughing, cermet is your secret weapon for achieving "high-end" finishes and holding sub-micron tolerances over large production runs.

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.
