Tungaloy CCMT09T304-PS AH725 Turning Insert

High-Precision PVD Coating | Versatile AH725 Grade | Expert Chip Control for Finishing

Why is the CCMT09T304-PS AH725 the top choice for stainless steel?

The Tungaloy CCMT09T304-PS AH725 is a high-performance PVD coated carbide turning insert engineered for reliability across a wide range of materials, including stainless steel, carbon steel, and heat-resistant alloys. The AH725 grade is a legendary multi-purpose grade that combines a tough carbide substrate with a specialized PVD coating to resist oxidation and built-up edges. This indexable turning tool features the PS-style chipbreaker, a ground geometry specifically designed for finishing to light semi-finishing, providing exceptional chip control and reducing cutting forces during CNC machining. With its 0.4mm corner radius, it is the perfect precision machining solution for users demanding a superior surface finish and consistent tool life. Made in Japan, it represents the pinnacle of industrial tooling quality.

How does the AH725 grade manage high heat in stainless turning?

The AH725 grade features a specialized multi-layered PVD (Physical Vapor Deposition) coating that provides high hardness and excellent thermal stability. Unlike CVD coatings, PVD is thinner and smoother, allowing the indexable turning tool to maintain a sharper cutting edge. This long-tail keywords industry favorite is specifically designed to handle the "gummy" nature of stainless steel, preventing built-up edges and ensuring a highly predictable tool life in precision machining. It is the ideal grade for users seeking a balance between toughness and wear resistance during CNC machining.

What are the benefits of the PS chipbreaker geometry?

The PS Chipbreaker is a ground geometry that delivers precise chip control at light depths of cut. Its sharp edge and optimized rake angle reduce cutting pressure, which is essential for preventing vibration and chatter on thin workpieces or during internal boring. It ensures that chips are broken into small, manageable pieces, protecting the surface finish and increasing operator safety.

What are the recommended feeds and speeds for AH725?

Optimized for P (Steel) and M (Stainless Steel):

  • Cutting Speed (Vc): 70 - 200 m/min (Steel) | 50 - 160 m/min (Stainless)
  • Feed Rate (f): 0.05 - 0.15 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For stainless steel, the use of high-pressure coolant is highly recommended to manage chip heat.*

What do machinists say about this Tungaloy insert?

⭐⭐⭐⭐⭐ "Best for small stainless parts" - Lars J., Norway
"The AH725 grade is incredible. I've been using it for finishing 316 stainless and the tool life is nearly double my previous brand."

⭐⭐⭐⭐⭐ "Mirror finish every time" - Yuki T., Japan
"Authentic Tungaloy quality. The PS breaker handles the light finish passes perfectly. Highly recommend for precision lathe work."

⭐⭐⭐⭐ "Very stable and sharp" - David K., USA
"Consistency is why I buy Tungaloy. These CCMT09T3 inserts fit my SCLCR09 holders perfectly and cut like butter in alloy steel."

⭐⭐⭐⭐⭐ "Excellent chip control" - Luca B., Italy
"No more long stringy chips on my CNC. The PS breaker makes my life much easier. Great shipping speed too."

⭐⭐⭐⭐⭐ "Original product, works great" - Sarah P., UK
"Received genuine Japanese inserts. They perform exactly as described in the technical data. Will be ordering more."

Technical Q&A

Q: Can I use this for boring applications?

A: Yes! The sharp edge of the PS chipbreaker reduces radial force, making it an excellent choice for internal boring bars to minimize chatter.

Q: Is AH725 better than CVD grades for stainless?

A: For precision finishing and sticky materials, PVD (AH725) is usually preferred because the edge is sharper, which prevents work-hardening of the workpiece.

Q: Which tool holder is compatible?

A: This insert fits any standard **SCLCR09** or **SCLCR3/8** external turning holder or boring bar designed for 09T3 size inserts.

Expert Machining Tip: PVD Edge Sharpness

For precision machining in stainless steel, the PVD Coated Carbide (AH725) provides a significantly sharper edge than CVD. This allows for lower cutting temperatures and prevents the material from "smearing" on the insert, resulting in longer tool life and better dimensional accuracy.

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?
