Tungaloy SPMT090308-24 NS9530 Milling Insert

Precision Steel Milling | Premium NS9530 Cermet | 0.8mm Corner Radius

What is the best insert for a high-gloss finish in steel milling?

The Tungaloy SPMT090308-24 NS9530 is a premier cermet milling insert engineered for high-speed finishing of ISO P (Steel). By leveraging the NS9530 cermet grade, this insert provides exceptional chemical stability and resistance to oxidation, resulting in a mirror-like surface finish and superior dimensional accuracy. The 0.8mm corner radius offers enhanced edge strength and higher feed capabilities compared to smaller radii, making it ideal for stable, high-efficiency finishing. 100% Made in Japan, it is designed for CNC professionals who refuse to compromise on surface quality.

NS9530 Cermet Technology

A TiCN-based cermet grade that prevents Built-Up Edge (BUE). It maintains a sharp cutting edge much longer than standard carbide when machining steel at high speeds.

-24 Milling Geometry

Optimized for light-to-medium milling, the -24 chipbreaker ensures smooth chip flow and reduced cutting forces, protecting the workpiece from thermal deformation.

0.8mm Radius Strength

The 0.8mm (08) radius provides a more robust cutting point, allowing for increased feed rates and improved resistance to edge chipping during complex milling paths.

Global Professional Feedback

⭐⭐⭐⭐⭐ "Mirror Finish Success" - Hans W., Germany
"We use the SPMT090308-24 for the final pass on steel mold plates. The surface finish is absolute mirror quality. Cermet is much better than carbide here."

⭐⭐⭐⭐⭐ "Great for Production" - James D., USA
"Excellent size control. We run these on our high-speed mills and they hold tolerance for hours. Genuine Tungaloy quality."

⭐⭐⭐⭐ "Very Stable" - T. Sato, Japan
"The 0.8mm radius is very strong. We get much better tool life at higher feeds compared to the 0.4mm version. Sharp and reliable."

⭐⭐⭐⭐⭐ "Reliable B2B Supplier" - Lee W., Singapore
"Ordered in bulk from CNCHome-Beyond. Fast shipping and 100% authentic. The NS9530 is our standard for precision steel milling."

⭐⭐⭐⭐⭐ "No Vibrations" - Antonio R., Italy
"Reduced cutting forces significantly. The -24 breaker is very efficient at high speeds. Great value for Italian machining shops."

8. FAQ - Milling Support

Q: Can I use this for roughing?

A: No. Cermet is designed for precision finishing. For heavy roughing, we recommend T9125 carbide inserts.

Q: Does this fit standard 3/8" IC milling cutters?

A: Yes. SPMT090308 is the metric equivalent to SPMT 32.52, featuring a 9.525mm (3/8") Inscribed Circle.

Q: Why choose 0.8mm radius over 0.4mm?

A: The 0.8mm radius is stronger and allows for higher feed rates while maintaining a smooth surface finish, especially in stable setups.

Expert Tip: The Cermet Advantage

The **NS9530 Cermet** grade provides a much lower chemical affinity for steel than Tungsten Carbide. This means the workpiece material doesn't "stick" to the edge, preventing the dullness and jagged finishes caused by built-up edge. For the best "shine," keep your RPMs high and your feed consistent. Trust **Tungaloy Japan** for professional CNC results.

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.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.
