Tungaloy VBMT110302-PS AH725 Insert

Ultra-Precision 35° Rhombic | AH725 PVD Grade | 0.2mm Corner Radius

What is the best insert for fine profiling and super-finishing?

The Tungaloy VBMT110302-PS AH725 is a specialized 35-degree rhombic insert designed for intricate profiling and high-gloss finishing. With its sharp 0.2mm corner radius and the -PS (Positive Sharp) chipbreaker, it excels at removing micro-amounts of material while maintaining extreme dimensional stability. Powered by the AH725 PVD coating, this insert provides the ultimate edge toughness needed for stainless steel, heat-resistant alloys, and carbon steels. It is the go-to solution for machinists requiring a mirror finish and zero vibration on slender workpieces.

Extreme Sharpness

The 0.2mm radius and positive rake angle allow for effortless cutting with minimal tool pressure, preventing deflection in thin-walled parts.

AH725 Nano-Technology

A premium PVD grade that balances hardness and adhesion resistance, significantly reducing notch wear in stainless steel and superalloys.

-PS Chip Control

Specifically engineered for low depths of cut, ensuring that chips are broken and evacuated efficiently without marring the finished surface.

What Machinists are Saying

⭐⭐⭐⭐⭐ "Mirror Surface" - Luc D., France
"The 0.2mm radius is a lifesaver for our precision watch parts. The Ra value is consistently perfect."

⭐⭐⭐⭐⭐ "No Vibration" - Kenji S., Japan
"Very sharp. Use this on long, slender stainless shafts where other inserts caused chatter. Zero issues."

⭐⭐⭐⭐⭐ "Excellent Service" - Marcus W., USA
"Fast shipping from Beyond Li. Authentic Tungaloy Japan quality. The AH725 grade is incredibly stable."

8. FAQ - Professional Support

Q: Is the 0.2mm radius too fragile for semi-finishing?

A: Yes. A 0.2mm radius is optimized for final finishing. For semi-finishing or general use, we recommend the 0.4mm (VBMT110304).

Q: Can I use this on Titanium?

A: Yes. The AH725 grade and sharp -PS geometry are highly effective for heat-resistant superalloys like Titanium and Inconel.

Machining Tip: Profiling Stability

The **35° VBMT insert** is prone to vibration if the feed is too high. For the **0.2mm radius**, keep your feed rate below 0.1mm/rev to ensure the best Ra finish and avoid edge chipping. **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.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
