Tungaloy TCMT16T302-PS NS9530 Turning Insert

High-Precision Mirror Finishing | Advanced NS9530 Cermet | 0.2mm Corner Radius

What is the sharpest cermet insert for precision finishing steel?

The Tungaloy TCMT16T302-PS NS9530 is a high-performance triangular turning insert designed for the ultimate precision finishing of ISO P (Steel). Built with the NS9530 Cermet grade, this tool offers exceptional chemical stability and oxidation resistance, ensuring a glossy surface finish that exceeds standard carbide performance. The 0.2mm corner radius (02) and the -PS "Power Sharp" chipbreaker provide the sharpest cutting edge for light depths of cut, making it the industrial standard for fine internal boring and external profile finishing. 100% Made in Japan, it delivers uncompromising dimensional accuracy for your CNC operations.

NS9530 Cermet Tech

A titanium-based cermet grade designed to withstand high-speed cutting while resisting built-up edge (BUE). Perfect for maintaining mirror-like surfaces on high-carbon and alloy steels.

-PS Power Sharp Breaker

The highly positive -PS geometry effectively breaks chips at low feed rates and small depths of cut, preventing the workpiece damage often caused by long, stringy chips.

0.2mm Precision Radius

The ultra-small radius reduces cutting pressure significantly, minimizing vibration and tool deflection in small boring bars or thin-walled components.

Recommended Cutting Data (NS9530)

  • Cutting Speed (Vc): 100 - 280 m/min (Recommended for mirror finish)
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 1.0 mm

*Machinist Advice: Cermet is heat-sensitive. Run at high speeds but avoid heavy interrupted cuts to maintain tool edge integrity.*

4. Primary Applications

  • High-speed finishing of low-carbon and alloy steels.
  • Final dimensioning of small-diameter shafts and pins.
  • Boring operations where surface Ra values are critical.
  • Replacing grinding operations with hard-turning.

5. Equipment Compatibility

Universal fit for Tungaloy / ISO boring bars and turning holders designed for TCMT 16T3 size inserts (3/8" IC). Fits standard S-STFCR/L or STUCR/L shanks.

Global Machinist Reviews

⭐⭐⭐⭐⭐ "Mirror Surface" - Thomas B., Germany
"The NS9530 grade gives a shine that carbide cannot reach. 0.2mm radius is perfect for my fine pins."

⭐⭐⭐⭐⭐ "Best for Boring" - Hiroshi Y., Japan
"Stable performance in internal boring. Chips are small and evacuate perfectly. Authentic Tungaloy stock."

⭐⭐⭐⭐ "Great Service" - David R., USA
"Received original boxes in 5 days. These cermets last much longer in high-speed finishing runs."

⭐⭐⭐⭐⭐ "High Gloss Result" - Fabio M., Italy
"Exactly what we needed for the automotive shafts. Ra values are well within our tolerance now."

⭐⭐⭐⭐⭐ "Precision Choice" - Samuel L., Singapore
"The -PS breaker is very sharp. No vibration at all on the CNC lathe. Highly recommended partner."

8. FAQ - Professional Support

Q: Can I use this for Stainless Steel?

A: NS9530 is primarily for ISO P (Steel). For Stainless Steel (ISO M), we suggest PVD grades like AH725 to handle work-hardening better.

Q: Should I use coolant with cermet?

A: Cermet is sensitive to thermal shock. It's often better to cut dry or with high-pressure air to avoid micro-cracks on the edge.

Q: What is the benefit of the 0.2mm radius?

A: It allows for extremely fine detail and reduces cutting force, which prevents vibration in long boring applications.

Industrial Tip: Cermet NS9530 vs. Carbide

Select **Cermet NS9530** when your priority is a high-gloss surface and dimensional stability at high cutting speeds. Unlike carbide, cermet doesn't "weld" to the steel, keeping your tool edge sharp for longer production cycles. For precision machining, **Tungaloy Japan** is the professional choice.

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.
