Tungaloy CCMT09T304-PSS AH725 Turning Insert

PVD Coated Versatility | Stainless Steel Specialist | High Precision PSS Geometry

How does AH725 perform in challenging stainless steel turning?

The Tungaloy CCMT09T304-PSS AH725 is a high-toughness PVD coated carbide turning insert engineered for reliability across a wide range of materials, with a primary focus on stainless steel and heat-resistant alloys. The AH725 grade features a specialized AlTiN coating that provides a high thermal barrier and exceptional resistance to notch wear and built-up edge (BUE). This indexable turning tool incorporates the PSS-style chipbreaker, a "Super Finishing" geometry designed for shallow depths of cut and lower feed rates. Its 0.4mm corner radius provides the ideal balance of edge sharpness and structural integrity for precision CNC machining. Made in Japan, this insert is a benchmark for precision machining where tool life predictability and surface integrity are essential.

Is the PSS chipbreaker suitable for light finishing on CNC lathes?

The PSS Chipbreaker is specifically optimized for "Super Finishing" operations. It features a sharp rake angle that drastically reduces cutting forces, preventing vibration and chatter in thin-walled or small-diameter workpieces. This long-tail keywords industry favorite is widely used in CNC machining for stainless steel components where chip control is notoriously difficult. By pairing the PSS geometry with the AH725 PVD grade, the indexable turning tool remains sharp and heat-resistant, ensuring an exceptional surface finish and extended tool life compared to standard uncoated carbide.

Recommended Cutting Parameters for AH725

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

  • Cutting Speed (Vc): 70 - 220 m/min (depending on material)
  • Feed Rate (f): 0.05 - 0.15 mm/rev
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For stainless steel, ensure consistent coolant application to maximize PVD coating efficiency.*

Feedback from Global Machining Professionals

⭐⭐⭐⭐⭐ "Perfect for 316 Stainless" - Markus E., Germany
"The CCMT09T304-PSS in AH725 grade is my first choice for internal boring on 316 stainless. The chips break into small curls and the finish is excellent."

⭐⭐⭐⭐⭐ "Reliable Tool Life" - Kenji H., Japan
"Very stable PVD coating. We run these on our Nakamura lathes for small batches of stainless parts. Dimensional accuracy is very predictable."

⭐⭐⭐⭐ "Great Chip Control" - David L., USA
"The PSS geometry really makes a difference on light cuts. No more bird-nesting around the tool holder. Authentic Tungaloy quality."

⭐⭐⭐⭐⭐ "Versatile and Sharp" - Luca B., Italy
"I use these for both carbon steel and stainless. The AH725 grade handles the transition between materials without any issues. Very sharp edge."

⭐⭐⭐⭐⭐ "Authentic Japan Stock" - Tan S., Singapore
"Genuine product. Fast delivery. These inserts perform exactly as the catalog states. Highly recommended for CNC production."

Technical Q&A

Q: Can I use AH725 for interrupted cuts?

A: Yes, AH725 is a PVD coated carbide grade known for its high toughness. It is much better suited for light to medium interrupted cuts than brittle cermet grades.

Q: Which tool holders are compatible with CCMT09T3?

A: This insert fits any standard **SCLCR09** or **SCLCR3/8** turning holder or internal boring bar.

Q: Is this insert suitable for finishing aluminum?

A: AH725 is a coated grade. For aluminum, we recommend an uncoated, polished insert (like KS05F) to prevent material welding to the edge.

Expert Tip: PVD Carbide vs. Cermet

While cermet provides elite surface finishes in steel turning, PVD Carbide (AH725) is the superior choice for stainless steel. It offers the chemical stability and toughness required to prevent notch wear, ensuring a much longer tool life in high-temperature cutting zones.

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.
