Tungaloy VCMT110302-PS AH725 Insert

Precision Stainless Machining | AH725 PVD Toughness | Superior Surface Finish

What is the best carbide grade for finishing small stainless steel parts?

The Tungaloy VCMT110302-PS AH725 is a premium PVD-coated carbide turning insert engineered for high-precision finishing in challenging materials like stainless steel and heat-resistant alloys. Featuring the highly versatile AH725 grade, this insert combines a tough carbide substrate with a specialized PVD coating that excels in preventing chipping and notch wear. The 35-degree rhombic geometry provides ultimate clearance for profiling and copying operations. With an ultra-sharp 0.2mm corner radius and the -PS (Positive Sharp) chipbreaker, it ensures extremely low cutting resistance and superior dimensional accuracy on slender workpieces.

AH725 PVD Coating

A high-adhesion PVD coating that provides exceptional resistance to oxidation and chipping, making it ideal for the gummy nature of stainless steel.

0.2mm Corner Radius

Specifically designed for super-fine finishing and precision medical or electronic components where intricate detail and sharp corners are required.

-PS Sharp Breaker

The Positive Sharp geometry significantly reduces tool pressure, preventing part deflection and ensuring a clean chip break at very low depths of cut.

⭐⭐⭐⭐⭐ "Trusted Source" - James L., UK
"Beyond Li provides authentic Tungaloy. The AH725 grade lasts significantly longer than the knock-offs."

⭐⭐⭐⭐⭐ "No Chipping" - P. Rossi, Italy
"Excellent resistance to thermal shock. We use these for wet finishing with great results."

⭐⭐⭐⭐⭐ "Reliable" - S. Watanabe, Japan
"Consistent size control. The VCMT110302 is my standard for all fine profiling tasks."

8. FAQ - Engineering Support

Q: Is AH725 better than AH630?

A: AH725 is a general-purpose grade excellent for both steel and stainless. AH630 is more specialized for heavy-duty stainless cutting. For fine finishing, AH725 is often preferred.

Q: Can I use this for dry machining?

A: PVD coatings like AH725 can handle dry machining, but for stainless steel, using coolant is highly recommended to prevent built-up edge.

Q: Why is the corner radius only 0.2mm?

A: A 0.2mm radius reduces cutting pressure and allows for extremely sharp internal corners and fine surface finishes on small parts.

Expert Tip: Solving Deflection

If you experience part deflection on long, slender stainless shafts, the **VCMT110302-PS** is your best solution. The combined sharp radius and positive breaker reduce "push" against the part, ensuring your diameters stay true from start to finish. **Tungaloy Japan** - Excellence in Precision.

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.
