Description

Tungaloy TPMT110308-PS AH725 Insert

High-Al PVD Grade | -PS Sharp Finishing Geometry | 0.8mm Radius

What is the best insert for stainless steel with interrupted cuts?

The Tungaloy TPMT110308-PS AH725 is a high-performance triangular turning insert specifically engineered for the challenging machining of stainless steels and heat-resistant alloys. Featuring the advanced AH725 PVD coated grade and a reinforced 0.8mm corner radius, this tool provides exceptional edge strength and fracture resistance. The specialized -PS chipbreaker (Positive Sharp) ensures smooth chip evacuation at low-to-medium feed rates, preventing work-hardening. 100% Made in Japan, it is the professional industrial choice for high-precision CNC lathe operations.

AH725 Grade Technology

A high-aluminum content PVD coating that offers superior oxidation resistance and hardness, significantly extending tool life in high-heat stainless applications.

-PS Sharp Geometry

Designed with a positive rake angle to reduce cutting forces and heat. Ideal for finishing passes where surface integrity and chip control are critical.

Enhanced 0.8mm Radius

The 0.8mm corner radius (ANSI 2 size) provides higher productivity and better edge toughness compared to the 0.4mm version.

Professional Industrial Feedback

⭐⭐⭐⭐⭐ "Incredible Tool Life" - Mark T., USA
"We use the TPMT110308-PS on 316 stainless shafts. The AH725 grade holds its edge much longer than our previous carbide inserts. Very consistent performance."

⭐⭐⭐⭐⭐ "Fast Shipping & Genuine" - Sanjay R., India
"Authentic Tungaloy Japan stock. The 0.8 radius gave us a better finish than expected at higher speeds. Excellent B2B partner."

⭐⭐⭐⭐ "Smooth Cutting" - Luca G., Italy
"No chip nesting issues with the -PS breaker. Surface Ra is stable across the entire batch. High reliability."

⭐⭐⭐⭐⭐ "Bulletproof Toughness" - Dieter W., Germany
"Great for semi-finishing. Even with small vibrations in the boring bar, the 0.8 corner stays clean. Top quality."

⭐⭐⭐⭐⭐ "Professional Choice" - Kevin L., UK
"Spot on dimensions. We trust Tungaloy from Beyond for all our aerospace stainless components. Zero defects so far."

8. FAQ - Machining Support

Q: Can I use this for carbon steel finishing?

A: Yes, AH725 is a versatile grade. It excels in stainless but is also excellent for alloy steels where heat resistance and toughness are required.

Q: Why use the 0.8mm radius instead of 0.4mm?

A: The 0.8mm (08) radius offers higher cutting edge strength and allows for a faster feed rate, which is ideal for semi-finishing or dealing with light interruptions.

Q: Is AH725 a coated grade?

A: Yes, it is a PVD coated grade with a high-aluminum content, specifically designed for high oxidation resistance at the cutting edge.

Tech Tip: PVD vs. Work Hardening

The **AH725 PVD coating** is optimized for high-temperature stability. When combined with the **-PS sharp geometry**, it prevents the work-hardening of stainless steel by reducing cutting friction. **Tungaloy Japan** - Engineering your workshop's success.

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.
