Tungaloy DCMT11T308-PS T9115 Turning Insert

High-Speed Steel Finishing Expert | Premium T9115 CVD | Made in Japan

What is the best insert for stable high-speed steel finishing?

The Tungaloy DCMT11T308-PS T9115 is a high-performance CVD coated carbide turning insert specifically engineered for high-efficiency steel machining. Featuring the advanced T9115 grade, this insert utilizes a thick Al2O3 layer and Tungaloy's "PremiumTec" surface technology to provide extreme resistance to crater wear and heat during continuous cutting. The 0.8mm corner radius offers superior edge strength and allows for higher feed rates compared to smaller radii, ensuring stable precision machining. The -PS chipbreaker (Polish Style) is designed with a sharp rake angle to reduce cutting resistance and ensure excellent chip control at light to medium finishing depths. This Japan-made indexable turning tool is the ultimate CNC machining solution for reducing cycle times and maximizing tool life in carbon and alloy steel production. Using this long-tail keywords optimized insert guarantees professional results in every pass.

How does the T9115 CVD coating optimize steel turning?

The T9115 Grade is Tungaloy's premium solution for steel finishing. Its CVD (Chemical Vapor Deposition) coating is designed with high adhesion technology to prevent chipping under high-speed conditions. In precision machining, the 0.8mm radius provides the necessary bulk to handle heat while the -PS chipbreaker manages the chip flow to prevent scratching the workpiece. For CNC machining shops, this indexable turning tool offers massive throughput gains by allowing for higher Vc without sacrificing surface integrity. It is the gold standard for high-productivity steel finishing.

Recommended Cutting Parameters (T9115)

  • Cutting Speed (Vc): 150 - 350 m/min (Standard Steels)
  • Feed Rate (f): 0.08 - 0.25 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For best results, use high cutting speeds. CVD coatings thrive on heat to reduce friction and improve the "peeling" action.*

Feedback from Global Machinists

⭐⭐⭐⭐⭐ "Increased Efficiency" - David B., USA
"We run 1045 steel all day. Swapped to T9115 and bumped the speed to 300 m/min. Tool life is great and the 0.8mm radius is very stable."

⭐⭐⭐⭐⭐ "Premium Japan Quality" - M. Wagner, Germany
"Consistent performance across thousands of parts. The -PS chipbreaker breaks chips beautifully even at high speeds. Highly recommended."

⭐⭐⭐⭐ "Great for Heavy Finishing" - Hiroshi S., Japan
"The 0.8mm radius allows for a bit more aggressive feed while keeping the finish smooth. Very reliable for our CNC production."

⭐⭐⭐⭐⭐ "Heat Barrier is Real" - Antonio M., Italy
"CVD coating handles the high-speed heat much better than my previous PVD inserts. No more stopping for tool changes mid-batch."

⭐⭐⭐⭐⭐ "Genuine Tungaloy" - Sarah J., UK
"Authentic inserts. They perform exactly as the technical manual states. Excellent value for any professional shop."

Technical Tooling Q&A

Q: Can I use this for stainless steel?

A: T9115 is optimized for steel. For stainless, PVD grades like AH725 are better suited due to their ability to resist the sticky nature of the material.

Q: Is CVD better than cermet for finishing?

A: Cermet gives a higher "mirror" shine, but CVD (T9115) is much stronger and can handle higher speeds and heavier feed rates more reliably.

Q: Which tool holder fits the DCMT 11T3 size?

A: This insert fits standard ISO holders like SDJCR/L 1212/1616 or internal boring bars like S...-SDUCR11.

Expert Choice: CVD Coated Carbide for Steel

In precision machining, CVD Coated Carbide (T9115) is the best choice for high-volume steel production. It provides the thermal stability needed for high SFM while the PS chipbreaker keeps the workplace clean and safe.

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.
