Tungaloy CCMT09T302-PS AH725 Turning Insert

Professional Stainless Steel Machining | Sharp PVD AH725 Grade | PS Finishing Geometry

What makes the CCMT09T302-PS AH725 best for stainless steel finishing?

The Tungaloy CCMT09T302-PS AH725 is a premium PVD coated carbide turning insert specifically engineered for high-precision tasks in challenging materials like stainless steel and heat-resistant alloys. The AH725 grade is world-renowned for its "sharp-edge" retention and anti-adhesive properties, which effectively prevent the built-up edge common in gummy metals. This indexable turning tool features the PS-style chipbreaker, a ground geometry designed for ultra-fine finishing passes. With its 0.2mm corner radius, it allows for incredible detail and minimal cutting force during CNC machining. Manufactured in Japan, it ensures world-class consistency and extended tool life for precision machining projects.

How does the AH725 grade enhance machining stability?

The AH725 grade is a dedicated PVD (Physical Vapor Deposition) grade that utilizes a high-Al content AlTiN multi-layered coating. This technology provides an incredibly hard surface that remains stable under the high temperatures generated when cutting stainless steel. For precision machining, PVD is superior to CVD because it allows the insert to maintain a much sharper edge profile. This long-tail keywords industry favorite ensures high resistance to built-up edge and oxidation, leading to a much more predictable tool life in your CNC machining operations.

The PS Chipbreaker: Ground Geometry for Mirror Finishes

The PS Chipbreaker is a ground-profile geometry specifically optimized for finishing to light semi-finishing. Its sharp cutting edge reduces cutting resistance significantly, preventing workpiece deflection and vibration—crucial when working with thin diameters or boring bars. This indexable turning tool ensures excellent chip evacuation even at low depths of cut, providing a clean surface finish every time.

What are the recommended feeds and speeds for this insert?

Ideal for M (Stainless Steel) and S (Superalloys):

  • Cutting Speed (Vc): 50 - 160 m/min (165 - 525 SFM)
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 1.0 mm

*Note: Use high-pressure coolant to maximize the life of the PVD coating and ensure the best chip breaking.*

What are customers saying about Tungaloy AH725?

⭐⭐⭐⭐⭐ "The king of stainless" - Gustav H., Sweden
"AH725 is my only choice for 316 stainless parts. The edge stays sharp forever compared to other brands."

⭐⭐⭐⭐⭐ "Incredible detail" - Takeshi S., Japan
"Using the 0.2mm radius for precision lathe work in Tokyo. The PS breaker handles chips perfectly even at very low feed rates."

⭐⭐⭐⭐ "Very Sharp Edge" - James L., USA
"Fits my SCLCR09 tool holders perfectly. The mirror finish on my alloy steel parts is impressive. Great value for authentic Tungaloy."

⭐⭐⭐⭐⭐ "No more vibration" - Marco V., Italy
"We use these in long boring bars. The low cutting pressure of the PS geometry eliminated our chatter issues immediately."

⭐⭐⭐⭐⭐ "Genuine and Fast" - Liam O., Australia
"Hard to find original Tungaloy stock sometimes, but these are 100% genuine. Fast shipping and excellent performance."

Machinist Q&A

Q: Can I use this insert for carbon steel turning?

A: Yes. While AH725 is optimized for stainless, its sharpness and tough substrate make it an excellent choice for carbon steel when you need high surface quality and precision.

Q: Is this insert compatible with standard boring bars?

A: It fits any standard **SCLCR09** or **SCLCR3/8** external holder or boring bar designed for size 09 (3/8" IC) rhombic inserts.

Q: Why choose the 0.2mm radius instead of 0.4mm?

A: Choose the 0.2mm radius (02) for very sharp corners, smaller part details, and when you need to minimize cutting pressure to avoid vibration on unstable setups.

Expert Machining Tip: PVD vs. CVD for Stainless

When machining gummy materials like stainless steel, PVD Coated Carbide (AH725) is usually preferred over CVD. Its thinner, smoother coating keeps the cutting edge sharp, which prevents work-hardening of the material and reduces heat build-up. This is the secret to achieving consistent precision machining results.

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?
