Tungaloy CCMT060204-PS AH725 Turning Insert

High-Precision PVD Coating | Versatile AH725 Grade | Superior Stainless Steel Finishing

Why is the CCMT060204-PS AH725 recommended for multi-material turning?

The Tungaloy CCMT060204-PS AH725 is a high-performance PVD coated carbide turning insert designed for exceptional stability in stainless steel, steel, and heat-resistant alloys. Featuring the versatile AH725 grade, this insert provides a sharp cutting edge and excellent adhesion resistance, preventing the built-up edge common in gummy materials. The PS-style chipbreaker is specifically ground for finishing, offering superior chip control and low cutting resistance. With a standard 0.4mm corner radius, it is the ideal indexable turning tool for precision machining where surface quality and consistent tool life are paramount. Engineered in Japan, it ensures reliable performance for demanding CNC machining tasks.

How does the AH725 grade solve stainless steel machining issues?

The AH725 grade is a specialized PVD grade that excels in tough environments. Unlike CVD coatings, the PVD process allows for a thinner, more uniform coating that preserves the sharpness of the cutting edge. This long-tail keywords industry favorite uses a multi-layered AlTiN coating to resist heat and oxidation. For precision machining, this means significantly reduced crater wear and notch wear, which are common when cutting 304 or 316 stainless steel. It provides the stability required for modern CNC machining centers.

What is the advantage of the PS chipbreaker geometry?

The PS Chipbreaker is ground for finishing to semi-finishing applications. Its sharp edge geometry is designed to minimize cutting resistance, which helps prevent vibration on thin-walled workpieces. This indexable turning tool delivers excellent chip breaking at lower feed rates, keeping your work area clean and protecting the surface finish of your workpiece.

What are the recommended feeds and speeds for CCMT060204-PS?

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

  • Cutting Speed (Vc): 70 - 200 m/min (Steel) | 50 - 150 m/min (Stainless)
  • Feed Rate (f): 0.05 - 0.15 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For best results in stainless steel, always use high-quality coolant to manage the high temperatures at the cutting edge.*

What do professional machinists say about this Tungaloy insert?

⭐⭐⭐⭐⭐ "Perfect for Stainless" - Matthias R., Germany
"AH725 is easily the best grade for my stainless production runs. The 0.4mm radius gives me a great finish and the chips break perfectly with the PS breaker."

⭐⭐⭐⭐⭐ "Authentic Japanese Quality" - Hiroshi K., Japan
"Tungaloy reliability is high. These CCMT0602 inserts last 20% longer than the other brands I've tested for precision finishing."

⭐⭐⭐⭐ "Very stable tool life" - John D., USA
"Consistent performance across the whole box. I use them on my small CNC lathe for alloy steel parts and the results are mirror-like."

⭐⭐⭐⭐⭐ "Great for boring" - Alessio M., Italy
"Excellent in small boring bars. Low pressure means no chatter. Highly recommended for precise internal turning."

⭐⭐⭐⭐⭐ "Quick shipping, great product" - Sarah L., UK
"Original packaging and genuine inserts. They performed exactly as expected on my titanium machining project."

Technical Support Q&A

Q: What tool holder is compatible with this insert?

A: It fits any standard **SCLCR06** or **SCLCR1/4** turning holder or boring bar designed for 0602 (1/4" IC) inserts.

Q: Can I use AH725 for machining cast iron?

A: While it can cut cast iron, AH725 is optimized for Steel and Stainless. For cast iron (K), grades like TH10 or AH120 would provide better tool life.

Q: What is the benefit of PVD over CVD for this model?

A: PVD (AH725) allows for a sharper edge than CVD, which is essential for precision finishing and machining gummy materials like stainless steel to prevent work hardening.

Expert Machining Tip: Managing Heat

When using PVD Coated Carbide (AH725) on stainless steel, watch your surface speed. While the coating is heat-resistant, excessive speeds can cause rapid flank wear. Stay within the recommended 70-150 m/min range for the best tool life in precision machining.

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?
