Tungaloy TPMT090208-PS AH725 Insert

Premium AH725 PVD Grade | -PS Chipbreaker | 0.8mm Corner Radius

What is the most reliable insert for stainless steel with interrupted cuts?

The Tungaloy TPMT090208-PS AH725 is a high-performance triangular turning insert specifically engineered for the demanding world of stainless steel and heat-resistant alloys. Featuring the versatile AH725 PVD coated grade and a reinforced 0.8mm corner radius, this insert offers superior edge strength compared to the 0.4mm version. The -PS chipbreaker provides stable chip evacuation during light-to-medium finishing and semi-finishing, effectively preventing tool notch wear. 100% Made in Japan, it ensures maximum stability in professional CNC environments.

AH725 Advanced Coating

A high-aluminum PVD coating that creates a hard, oxidation-resistant barrier. It excels in minimizing thermal cracking and built-up edge (BUE).

Reinforced 0.8mm Radius

The larger corner radius enhances cutting edge strength and allows for higher feed rates while maintaining structural integrity during light interruptions.

PS Chip Control

Optimized for stainless steel, the -PS geometry breaks chips reliably at various depths of cut, ensuring a clean workpiece surface and safe automated operation.

3. Technical Data: ISO (Metric) vs. ANSI (Imperial)

Feature Metric (ISO) Imperial (ANSI)
Standard Model TPMT090208-PS TPMT 1.8(1.5)2-PS
Inscribed Circle (IC) 5.56 mm 7/32"
Thickness (S) 2.38 mm 3/32"
Corner Radius (RE) 0.8 mm 1/32"

Recommended Cutting Parameters (Stainless Steel)

  • Cutting Speed (Vc): 50 - 170 m/min (Stainless Steel)
  • Feed per Rev (f): 0.10 - 0.25 mm/rev (Enhanced by 0.8mm Radius)
  • Depth of Cut (ap): 0.5 - 2.5 mm

*Note: Ensure rigidity of the machine. The 0.8mm radius allows for higher productivity but requires stable workholding.*

4. Primary Applications

  • General turning of Austenitic Stainless Steels (SUS304, SUS316).
  • Machining of heat-resistant alloys and Inconel.
  • Semi-finishing operations with light interruptions.
  • Boring and external turning in small components.

5. Tool Compatibility

Fits all standard ISO TPMT 0902 tool holder pockets. Specifically optimized for STFCR/L and STGCR/L holder series. Compatible with Star, Citizen, Mazak, and Haas CNC equipment.

Industrial Feedback

⭐⭐⭐⭐⭐ "Bulletproof in 304 Stainless" - Mark T., USA
"Switched from the 0.4 radius to this 0.8 version for semi-finishing. The tool life doubled and the chips are much more manageable."

⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Sanjay G., India
"Always genuine Tungaloy stock. The AH725 grade is my first choice for stainless valves. Fast shipping to Mumbai."

⭐⭐⭐⭐ "Great Chip Control" - Luca M., Italy
"The -PS breaker handles different depths of cut without creating stringy nests. Very stable performance."

⭐⭐⭐⭐⭐ "Perfect for Production" - Dieter S., Germany
"Excellent toughness. Even with small interruptions in the cut, the 0.8mm radius keeps the edge clean. Very satisfied."

⭐⭐⭐⭐⭐ "Authentic Quality" - Kevin L., UK
"Spot on dimensions. We hit our tolerances every time. The mirror finish on stainless is impressive for a 0.8 radius."

8. FAQ - Professional Support

Q: When should I choose the 0.8mm radius over 0.4mm?

A: Choose the 0.8mm (08) when you need higher edge strength, higher feed rates, or if you are dealing with light interrupted cuts. Use 0.4mm (04) for finer finishes and lower cutting forces.

Q: What makes AH725 the standard for stainless?

A: AH725 uses a high-Al-content PVD coating which provides extreme hardness and thermal stability. It resists the work-hardening effect common in stainless steels.

Q: Can I use this for dry machining?

A: While AH725 is heat resistant, coolant is highly recommended for stainless steel to clear chips from the cutting zone and prevent Built-Up Edge (BUE).

Industrial Tip: Cutting Edge Toughness

The **AH725 grade** is Tungaloy's premier PVD solution for stainless. By pairing it with a **0.8mm corner radius**, you maximize the volume of metal removed before edge failure. Ideal for semi-finishing operations where tool life and reliability are the top priorities. **Tungaloy Japan** - Engineering Excellence.

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.
