Tungaloy CCMT120404-PSS AH725 Turning Insert

High-Performance PVD Coating | Stainless Steel Finishing | Precision PSS Geometry

Why is AH725 the best choice for finishing stainless steel and exotic alloys?

The Tungaloy CCMT120404-PSS AH725 is a premium PVD coated carbide turning insert specifically engineered for stability and precision in difficult-to-cut materials. The AH725 grade utilizes a specialized AlTiN (Aluminum Titanium Nitride) coating that offers superior thermal resistance and prevents notch wear, which is common in stainless steel applications. This indexable turning tool features the PSS-style chipbreaker, a ground geometry designed for light depths of cut and low feed rates, ensuring a "Super Finishing" quality. With a 0.4mm corner radius, it provides the sharpest edge possible for CNC machining without sacrificing tool life. Made in Japan, this insert is the ultimate solution for precision machining where surface integrity and predictable performance are top priorities.

How does the PSS chipbreaker manage chips in gummy materials?

The PSS Chipbreaker is a specialized "Super Finishing" geometry designed for CNC operators who face issues with long, stringy chips in materials like 304 or 316 stainless steel. Its sharp rake angle and optimized groove profile ensure that chips are curled and broken even at shallow depths of cut. This long-tail keywords solution reduces radial cutting pressure, preventing chatter on delicate parts. When combined with the AH725 PVD grade, this indexable turning tool maintains its sharp edge against the work-hardening tendencies of stainless steels, delivering a significantly longer tool life in CNC machining environments.

Recommended Cutting Parameters for AH725

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

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

*Note: Use high-pressure coolant to improve chip evacuation and maximize the PVD coating's thermal barrier.*

Feedback from CNC Machinists Worldwide

⭐⭐⭐⭐⭐ "Perfect for internal boring in 304 SS" - Markus E., Germany
"The CCMT12 size is robust, and the PSS geometry is amazing. No bird-nesting on the finish passes. AH725 is very stable."

⭐⭐⭐⭐⭐ "Reliable and consistent" - Kenji T., Japan
"Consistent tool life even with interrupted cuts. Tungaloy Japan quality is hard to beat for high-precision CNC work."

⭐⭐⭐⭐ "Great surface finish" - James W., USA
"Switched from another brand to these for our stainless batches. Surface roughness decreased significantly. Authentic product."

⭐⭐⭐⭐⭐ "Excellent heat resistance" - Paolo M., Italy
"The AlTiN coating really works on heat-resistant alloys. I run these at 150m/min and they just keep cutting."

⭐⭐⭐⭐⭐ "Fast shipping, top tool" - Tan W., Singapore
"Arrived quickly. These inserts perform exactly as the Tungaloy catalog says. Very sharp edge and high build quality."

Technical Tooling Q&A

Q: Can I use AH725 for interrupted cuts?

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

Q: What tool holders fit the CCMT1204 size?

A: These inserts fit any standard **SCLCR12** (Metric) or **SCLCR1/2** (Imperial) turning holders and boring bars.

Q: Is this insert suitable for dry machining?

A: While the PVD coating handles heat well, we always recommend coolant for finishing stainless steel to prevent work-hardening and improve surface Ra.

Expert Insight: PVD Carbide vs. Cermet

For precision machining in stainless steel, PVD Carbide (AH725) is the superior choice over cermet. It provides the necessary toughness to resist chemical wear and notch wear, ensuring a much more reliable 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.
