Tungaloy TPMT110304-PS AH725 Insert

High-Al PVD Coated | -PS Finishing Chipbreaker | Japan Precision

How do I stop built-up edge when turning stainless steel?

The Tungaloy TPMT110304-PS AH725 is a premium triangular turning insert designed to master the challenges of stainless steel and heat-resistant superalloys (HRSA). Utilizing the advanced AH725 PVD coating, this insert provides exceptional oxidation resistance and surface hardness. The -PS chipbreaker features a sharp cutting edge and specialized rake geometry, specifically engineered for precision finishing and light-to-medium cutting. 100% Made in Japan, it is the industrial benchmark for reducing cycle times and improving surface Ra values.

AH725 Grade Tech

A high-aluminum content PVD coating that prevents thermal cracking and adheres tightly to the carbide substrate, significantly extending tool life in wet or dry conditions.

-PS Chipbreaker

Optimized for finishing (PS = Positive Sharp), this geometry ensures excellent chip evacuation at small depths of cut, preventing "bird-nesting" and part damage.

Reliable Toughness

The sub-micron carbide substrate offers superior fracture toughness, making it stable even during light interrupted cuts on CNC lathes.

Professional Machinist Feedback

⭐⭐⭐⭐⭐ "Best Grade for 316L" - Robert K., USA
"The AH725 grade from Beyond has been a game-changer for our stainless valve production. Tool life increased by 40% over our previous supplier."

⭐⭐⭐⭐⭐ "No more chip nesting" - Lars H., Sweden
"Excellent chip control. The -PS geometry breaks chips cleanly even at very low depths of cut. Highly reliable for overnight production."

⭐⭐⭐⭐ "Great Service" - Hiroshi M., Japan
"Authentic Tungaloy stock. Precise dimensions and high-quality coating. Shipping was faster than expected."

⭐⭐⭐⭐⭐ "Mirror Finish" - Giacomo V., Italy
"Even though it's carbide, the surface finish we get on stainless parts is close to cermet. Very impressive grade."

⭐⭐⭐⭐⭐ "Top B2B Partner" - Rajesh P., India
"Very professional support. The TPMT110304 is exactly as described. Will continue to source all our Tungaloy needs here."

8. FAQ - Professional Support

Q: Can I use AH725 for carbon steel?

A: Yes, AH725 is a versatile grade. While optimized for stainless, it performs exceptionally well on carbon and alloy steels where toughness is required.

Q: What is the benefit of the -PS breaker?

A: It is a positive, sharp geometry. It lowers cutting resistance and provides the best chip control in finishing operations compared to standard universal breakers.

Q: Does this insert require coolant?

A: While it can be used for dry cutting, we highly recommend coolant when machining stainless steel to prevent chip welding and ensure the longest tool life.

Tech Tip: PVD vs. CVD in Stainless Steel

The **AH725 PVD coating** is much thinner and smoother than CVD coatings, which allows the cutting edge to remain sharp. This is critical for **Stainless Steel**, as a dull edge causes work-hardening. **Tungaloy Japan** - Engineering the future of CNC machining.

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.
