Tungaloy DCGT11T302FN-JS SH730 Turning Insert

High-Precision Finishing Master | SH730 Wear-Resistance PVD | Made in Japan

What is the best carbide insert for high-speed finishing of stainless steel?

The Tungaloy DCGT11T302FN-JS SH730 is a premium precision machining solution engineered for the most demanding finishing operations. Featuring the advanced SH730 PVD grade, this insert offers an upgraded coating hardness compared to previous generations, providing exceptional resistance to crater wear and oxidation. The -JS chipbreaker geometry is a "ground periphery" style designed for light-duty finishing passes, ensuring that cutting forces remain low to prevent vibration and workpiece deflection. This Japan-made indexable turning tool is ideal for CNC machining of small-diameter components in medical and aerospace sectors. By utilizing this long-tail keywords optimized insert, your shop can achieve sub-micron surface Ra values while maintaining significant tool life in high-velocity cutting environments.

How does the SH730 grade handle sticky materials?

The SH730 Grade represents the pinnacle of PVD Coated Carbide technology. It is specifically formulated to handle the heat and stickiness of Austenitic Stainless Steel and Duplex alloys. The -JS chipbreaker geometry is neutral (N), allowing for high-precision finishing in both directions when using specialized Swiss-type tool paths. In precision machining, having a ground periphery insert like the DCGT11T302FN-JS ensures that the edge is as sharp as possible, leading to reduced burr formation and a "cleaner" cut. For shops running high-performance CNC machining lathes, SH730 provides the thermal stability needed to increase cutting speeds without sacrificing part accuracy.

Recommended Cutting Parameters for SH730

  • Cutting Speed (Vc): 80 - 200 m/min
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.10 - 1.20 mm

*Optimization Tip: Use high-pressure coolant directed exactly at the cutting zone to maximize the crater resistance of the SH730 coating.*

Feedback from Global Precision Workshops

⭐⭐⭐⭐⭐ "Mirror Surface" - David R., USA
"Switching to SH730 on our stainless parts made a huge difference. The Ra finish is consistent through the whole batch."

⭐⭐⭐⭐⭐ "Best for Finish Passes" - M. Schneider, Germany
"Extremely sharp edge and very tight tolerances. Tungaloy Japan quality is unbeatable for precision components."

⭐⭐⭐⭐ "Great Chip Control" - Giovanni L., Italy
"The JS breaker is perfect for light finishing. No more bird-nesting on our Swiss lathes."

⭐⭐⭐⭐⭐ "Stable Tool Life" - Kenji T., Japan
"High stability in high-speed applications. SH730 is a great upgrade over the older SH725 for heat resistance."

⭐⭐⭐⭐⭐ "Authentic Quality" - Liam F., Australia
"Genuine product, very well packaged. Performance on alloy steel finishing is top-notch."

Technical Tooling Q&A

Q: Is SH730 harder than SH725?

A: Yes, SH730 has higher hardness and improved thermal resistance, making it more suitable for high-speed finishing and difficult stainless materials.

Q: Can I rough with the JS chipbreaker?

A: No. The -JS breaker is designed specifically for small depths of cut and light finishing. Roughing will likely cause edge breakage.

Q: What holder does this fit?

A: It fits any standard DCGT 11T3 holder, including SDJCR, SDJCL, and SDNCN series tool holders.

Material Choice Tip: SH730 vs. CVD

While CVD coatings are thick and tough for heavy roughing, PVD Coated Carbide like SH730 is essential for precision machining. The thinner PVD layer allows for a sharper micro-edge, providing the superior surface finish required for high-precision components.

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.
