Tungaloy SCMT09T304-PS AH725 Insert
Multi-Purpose Turning | -PS Precision Breaker | Premium AH725 PVD Grade
What is the most versatile PVD insert for steel and stainless?
The Tungaloy SCMT09T304-PS AH725 is a highly adaptable square carbide turning insert engineered for a wide range of machining applications. Featuring the specialized AH725 PVD coated grade, this tool excels in providing a sharp cutting edge with high chipping resistance, making it ideal for small-part machining and general turning. The -PS chipbreaker is specifically designed for finishing to light-medium cutting, offering superior chip control even at low feed rates. Manufactured in Japan, this CNC square insert is a reliable workhorse for precision components in medical, aerospace, and general engineering sectors.
AH725 Tough PVD Grade
A dedicated PVD grade that combines a high-Al content coating with a tough substrate. Excellent for resisting flank wear and edge buildup.
-PS Precision Chipbreaker
Features a positive geometry that reduces cutting force and ensures smooth chip flow, specifically during finishing operations.
Sharp Edge Integrity
Maintains a very sharp cutting edge, which is essential for machining gummy materials like stainless steel or low-carbon steel.

8. FAQ - Professional Support
Q: Is AH725 better than AH120?
A: AH725 is a more modern PVD grade with higher wear resistance for steel, while AH120 is often preferred for general-purpose cast iron machining.
Q: Can I use this for dry cutting?
A: While AH725 has high heat resistance, using coolant is recommended for stainless steel to prevent chip welding and enhance surface finish.
Q: Will this fit my manual lathe?
A: Yes, as long as you have a tool holder that accepts SCMT 09T3 (or SCMT 32.5) square inserts.
Expert Insight: Why PVD for Finishing?
Unlike thicker CVD coatings, PVD (Physical Vapor Deposition) allows for a much thinner and sharper cutting edge. The AH725 grade leverages this sharpness alongside high-Al coating technology to provide the stability needed for precision finishing. If you are struggling with vibration or poor surface finish on smaller parts, the SCMT09T304-PS is your ultimate solution.
