Tungaloy CCMT09T308-PSS AH725 Turning Insert

PVD Coated Edge Strength | Stainless Steel Specialist | High Precision PSS Geometry

How does AH725 provide stability in interrupted stainless steel cuts?

The Tungaloy CCMT09T308-PSS AH725 is a high-performance PVD coated carbide turning insert engineered for reliability in demanding environments. The AH725 grade features a specialized AlTiN coating that offers a superior thermal barrier and exceptional resistance to notch wear and built-up edge (BUE), making it perfect for precision machining of stainless steel and heat-resistant alloys. This indexable turning tool is equipped with the PSS-style chipbreaker, a "Super Finishing" geometry that excels at managing chips at low feed rates. With a robust 0.8mm corner radius, it provides maximum edge strength for stable CNC machining. Made in Japan, this insert ensures a predictable and long tool life for modern industrial production.

Technical Specs: Metric vs. Imperial Equivalence

Specifications Metric (Standard) Imperial Equiv.
Product Model CCMT09T308-PSS CCMT32.52-PSS
Inscribed Circle (IC) 9.525 mm 3/8 inch
Corner Radius (RE) 0.8 mm 1/32 inch

Why is the 0.8mm radius combined with PSS geometry better for tool life?

The 0.8mm corner radius on the CCMT09T308-PSS significantly increases the cross-sectional area of the cutting edge, allowing for better heat dissipation and higher resistance to chipping. The PSS Chipbreaker complements this by providing a sharp cutting action that reduces radial pressure. This long-tail keywords industry favorite is widely used in CNC machining for finishing stainless steel parts where chip control is critical. By pairing this geometry with the AH725 PVD grade, the indexable turning tool remains sharp and stable, delivering an exceptional surface finish and superior tool life compared to smaller radii in tough materials.

Recommended Cutting Parameters for AH725

Optimized for M (Stainless), P (Steel), and S (Superalloys):

  • Cutting Speed (Vc): 80 - 220 m/min (depending on material)
  • Feed Rate (f): 0.08 - 0.20 mm/rev
  • Depth of Cut (ap): 0.3 - 2.0 mm

*Pro Tip: For stainless steel, ensure high-pressure coolant is aimed at the cutting zone to prevent thermal cracking.*

What do global machinists say about this insert?

⭐⭐⭐⭐⭐ "Extreme stability in 304 SS" - Markus R., Germany
"The 0.8mm radius combined with the AH725 grade makes this insert incredibly tough. I used it for finishing 304 stainless shafts and the tool life was doubled."

⭐⭐⭐⭐⭐ "Best chip control for finishing" - Kenji S., Japan
"The PSS geometry is perfect. Even at low feed rates, the chips are manageable and don't wrap. Authentic Tungaloy quality."

⭐⭐⭐⭐ "Great for semi-finishing too" - David B., USA
"Because it's a 08 radius, I can push it a bit harder in semi-finishing and it still gives a great final surface. Very versatile."

⭐⭐⭐⭐⭐ "Handles heat very well" - Antonio L., Italy
"The AlTiN coating on the AH725 grade is top tier. Even dry cutting some alloy steels, the insert stays sharp for a long time."

⭐⭐⭐⭐⭐ "Original product, fast delivery" - Liam F., Australia
"Genuine Tungaloy Japan inserts. Packaging was perfect and the performance is exactly what I expected. Highly recommend this shop."

Technical Machinist Q&A

Q: Is this insert better than cermet for stainless steel?

A: Yes. While cermet gives a better finish on carbon steel, AH725 PVD carbide has the toughness and chemical stability to prevent notch wear in stainless steel.

Q: Which tool holders fit the CCMT09 size?

A: These fit any standard **SCLCR09** or **SCLCR3/8** external turning holders and boring bars.

Q: Can I use this for interrupted cuts?

A: AH725 is a very tough grade, making it suitable for light to medium interrupted cuts where cermet would chip.

Expert Tip: PVD Carbide vs. Cermet

When precision machining involves stainless steel or heat-resistant alloys, PVD Carbide (AH725) is the superior choice. It offers the high-temperature toughness required to prevent sudden edge failure, ensuring a consistent tool life in high-efficiency 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.
