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.

"I used these for internal boring on a Swiss lathe. The -PS breaker is very sharp and prevents vibration."

⭐⭐⭐⭐⭐ "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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
