Tungaloy CCMT060202-PS AH725 Turning Insert

Precision PVD Coating | Versatile AH725 Grade | 0.2mm Radius for Fine Finishing

What makes CCMT060202-PS AH725 ideal for precision CNC turning?

The Tungaloy CCMT060202-PS AH725 is a high-performance PVD coated carbide turning insert engineered for exceptional versatility across multiple materials, especially stainless steel and heat-resistant alloys. Featuring the legendary AH725 grade, this insert combines a tough carbide substrate with a specialized PVD coating to resist built-up edges and oxidation. The PS-style chipbreaker is precision-ground for light finishing, ensuring excellent chip control even at minimal depths of cut. With its sharp 0.2mm corner radius, it is the ultimate indexable turning tool for precision machining where tight tolerances and a mirror-like surface finish are mandatory. Made in Japan, it provides a reliable and long tool life for high-end manufacturing.

Why is the AH725 grade so effective for sticky materials?

The AH725 grade is a specialized PVD coated grade featuring a high-density, multi-layered AlTiN coating. Unlike CVD grades, PVD is thinner and allows for a much sharper cutting edge. This long-tail keywords industry standard is specifically designed to combat "built-up edge" (BUE) which is common when machining stainless steel and titanium. For precision machining of small components, AH725 provides the sharpness and heat resistance needed to maintain dimensional accuracy throughout the CNC machining process.

The PS Chipbreaker: Ground for Ultra-Fine Finishing

The PS Chipbreaker is a ground geometry that facilitates smooth chip evacuation even at low feed rates. When paired with the 0.2mm radius, this indexable turning tool creates very low cutting resistance. This is critical when working with small diameters or thin workpieces where tool pressure could cause deflection or vibration.

What are the recommended feeds and speeds for AH725?

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

  • Cutting Speed (Vc): 50 - 150 m/min (Stainless) | 70 - 200 m/min (Steel)
  • Feed Rate (f): 0.03 - 0.12 mm/rev
  • Depth of Cut (ap): 0.1 - 1.0 mm

*Pro Tip: Use high-pressure coolant to maximize tool life when machining stainless steel alloys.*

Reviews from the Professional Machining Community

⭐⭐⭐⭐⭐ "Killer on 304 Stainless" - Erik V., Sweden
"I was struggling with chip wrapping on 304 stainless until I tried the PS breaker. The AH725 grade holds an edge way longer than my previous PVD inserts."

⭐⭐⭐⭐⭐ "Best for small parts" - Yuki M., Japan
"The 0.2mm radius is perfect for fine details. Tungaloy Japan quality is unbeatable for precision lathe work."

⭐⭐⭐⭐ "Very Sharp and Stable" - Tom H., USA
"I use these for finishing passes on alloy steel. The surface finish is mirror-like. Consistently good tool life."

⭐⭐⭐⭐⭐ "Perfect for boring bars" - Alessio D., Italy
"We use these in our small SCLCR boring bars. The low cutting force of the PS geometry prevents chatter perfectly."

⭐⭐⭐⭐⭐ "Authentic product" - Liam F., Australia
"Original Tungaloy boxes, fast shipping. Performs exactly as the technical sheet promised for my stainless project."

Technical Q&A

Q: Can I use AH725 for dry machining?

A: While the PVD coating is heat-resistant, coolant is highly recommended for stainless steel to prevent thermal cracking and built-up edge.

Q: What tool holder fits this insert?

A: This insert fits any **SCLCR06** or **SCLCL1/4** holder or boring bar designed for 80-degree rhombic inserts of size 0602.

Q: Why choose the 0.2mm radius over 0.4mm?

A: Use the 0.2mm radius (02) for ultra-fine finishing, sharp corners, and to minimize vibration on thin-walled parts.

Expert Machining Tip: PVD vs. CVD

For stainless steel and precision finishing, PVD Coated Carbide like AH725 is superior to CVD because it allows for a sharper edge. This sharpness reduces the "rubbing" effect, which helps prevent work-hardening of the material and ensures a superior 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.
