Tungaloy CCMT09T304-PSS AH725 Turning Insert

PVD Coated Versatility | Stainless Steel Specialist | High Precision PSS Geometry

How does AH725 perform in challenging stainless steel turning?

The Tungaloy CCMT09T304-PSS AH725 is a high-toughness PVD coated carbide turning insert engineered for reliability across a wide range of materials, with a primary focus on stainless steel and heat-resistant alloys. The AH725 grade features a specialized AlTiN coating that provides a high thermal barrier and exceptional resistance to notch wear and built-up edge (BUE). This indexable turning tool incorporates the PSS-style chipbreaker, a "Super Finishing" geometry designed for shallow depths of cut and lower feed rates. Its 0.4mm corner radius provides the ideal balance of edge sharpness and structural integrity for precision CNC machining. Made in Japan, this insert is a benchmark for precision machining where tool life predictability and surface integrity are essential.

Is the PSS chipbreaker suitable for light finishing on CNC lathes?

The PSS Chipbreaker is specifically optimized for "Super Finishing" operations. It features a sharp rake angle that drastically reduces cutting forces, preventing vibration and chatter in thin-walled or small-diameter workpieces. This long-tail keywords industry favorite is widely used in CNC machining for stainless steel components where chip control is notoriously difficult. By pairing the PSS geometry with the AH725 PVD grade, the indexable turning tool remains sharp and heat-resistant, ensuring an exceptional surface finish and extended tool life compared to standard uncoated carbide.

Recommended Cutting Parameters for AH725

High performance for M (Stainless), P (Steel), and S (Superalloys):

Cutting Speed (Vc): 70 - 220 m/min (depending on material)
Feed Rate (f): 0.05 - 0.15 mm/rev
Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For stainless steel, ensure consistent coolant application to maximize PVD coating efficiency.*

Feedback from Global Machining Professionals

⭐⭐⭐⭐⭐ "Perfect for 316 Stainless" - Markus E., Germany
"The CCMT09T304-PSS in AH725 grade is my first choice for internal boring on 316 stainless. The chips break into small curls and the finish is excellent."

⭐⭐⭐⭐⭐ "Reliable Tool Life" - Kenji H., Japan
"Very stable PVD coating. We run these on our Nakamura lathes for small batches of stainless parts. Dimensional accuracy is very predictable."

⭐⭐⭐⭐ "Great Chip Control" - David L., USA
"The PSS geometry really makes a difference on light cuts. No more bird-nesting around the tool holder. Authentic Tungaloy quality."

⭐⭐⭐⭐⭐ "Versatile and Sharp" - Luca B., Italy
"I use these for both carbon steel and stainless. The AH725 grade handles the transition between materials without any issues. Very sharp edge."

⭐⭐⭐⭐⭐ "Authentic Japan Stock" - Tan S., Singapore
"Genuine product. Fast delivery. These inserts perform exactly as the catalog states. Highly recommended for CNC production."

Technical Q&A

Q: Can I use AH725 for interrupted cuts?

A: Yes, AH725 is a PVD coated carbide grade known for its high toughness. It is much better suited for light to medium interrupted cuts than brittle cermet grades.

Q: Which tool holders are compatible with CCMT09T3?

A: This insert fits any standard **SCLCR09** or **SCLCR3/8** turning holder or internal boring bar.

Q: Is this insert suitable for finishing aluminum?

A: AH725 is a coated grade. For aluminum, we recommend an uncoated, polished insert (like KS05F) to prevent material welding to the edge.

Expert Tip: PVD Carbide vs. Cermet

While cermet provides elite surface finishes in steel turning, PVD Carbide (AH725) is the superior choice for stainless steel. It offers the chemical stability and toughness required to prevent notch wear, ensuring a much longer tool life in high-temperature cutting zones.

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.
