Tungaloy TPMT110304-PS AH725 Insert

High-Al PVD Coated | -PS Finishing Chipbreaker | Japan Precision

How do I stop built-up edge when turning stainless steel?

The Tungaloy TPMT110304-PS AH725 is a premium triangular turning insert designed to master the challenges of stainless steel and heat-resistant superalloys (HRSA). Utilizing the advanced AH725 PVD coating, this insert provides exceptional oxidation resistance and surface hardness. The -PS chipbreaker features a sharp cutting edge and specialized rake geometry, specifically engineered for precision finishing and light-to-medium cutting. 100% Made in Japan, it is the industrial benchmark for reducing cycle times and improving surface Ra values.

AH725 Grade Tech

A high-aluminum content PVD coating that prevents thermal cracking and adheres tightly to the carbide substrate, significantly extending tool life in wet or dry conditions.

-PS Chipbreaker

Optimized for finishing (PS = Positive Sharp), this geometry ensures excellent chip evacuation at small depths of cut, preventing "bird-nesting" and part damage.

Reliable Toughness

The sub-micron carbide substrate offers superior fracture toughness, making it stable even during light interrupted cuts on CNC lathes.

8. FAQ - Professional Support

Q: Can I use AH725 for carbon steel?

A: Yes, AH725 is a versatile grade. While optimized for stainless, it performs exceptionally well on carbon and alloy steels where toughness is required.

Q: What is the benefit of the -PS breaker?

A: It is a positive, sharp geometry. It lowers cutting resistance and provides the best chip control in finishing operations compared to standard universal breakers.

Q: Does this insert require coolant?

A: While it can be used for dry cutting, we highly recommend coolant when machining stainless steel to prevent chip welding and ensure the longest tool life.

Tech Tip: PVD vs. CVD in Stainless Steel

The **AH725 PVD coating** is much thinner and smoother than CVD coatings, which allows the cutting edge to remain sharp. This is critical for **Stainless Steel**, as a dull edge causes work-hardening. **Tungaloy Japan** - Engineering the future of CNC machining.

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.
