High-Toughness PVD Grade for Stainless Steel & Exotic Alloys
Product Overview
"Which insert is most reliable for preventing work hardening and notch wear when turning 304 or 316 stainless steel?"
The TaeguTec TNMG 160408 EM TT9080 is a high-performance PVD-coated solution specifically optimized for ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys). The TT9080 grade features a fine-grained substrate with a specialized PVD coating that provides exceptional thermal stability and edge toughness. The EM (Medium-duty) chipbreaker is designed with a sharp cutting edge to reduce cutting forces and minimize heat transfer to the workpiece, effectively preventing the work-hardening issues common in stainless steel turning. With its 0.8mm corner radius, this insert provides the perfect balance of edge strength and surface finish quality for versatile industrial applications.
Key Performance Advantages
TT9080 Thermal Resilience
Advanced PVD coating prevents built-up edge (BUE) and offers superior resistance to chemical wear in high-temp alloys.
EM Chip Management
The EM geometry ensures stable chip breaking across a wide range of feed rates, reducing machine downtime from "bird-nesting."
Notch Wear Resistance
Specifically engineered to combat the concentrated wear at the depth-of-cut line typical of stainless steel machining.

Why Choose TaeguTec TT9080?
Machining stainless steel is notoriously difficult due to its tendency to stick to the cutting edge and work-harden under pressure. The TaeguTec TT9080 grade is engineered specifically to overcome these challenges. By using a specialized PVD coating that maintains hardness at high temperatures and an EM chipbreaker that clears chips efficiently, this insert allows you to maintain aggressive cycle times without risking tool failure. The triangular design provides 6 usable cutting edges, offering an exceptional cost-to-performance ratio for your production line.

Frequently Asked Questions
Q: Can I use TT9080 for mild steel? A: While it will work, it is optimized for stainless. For standard carbon steel, the TT8125 or TT9225 grades will provide a more economical tool life.
Q: Is the EM chipbreaker for finishing or roughing? A: The EM is a medium-duty chipbreaker. It covers a broad range from semi-finishing to light roughing in stainless steel.
Q: Should I use coolant with this insert? A: Yes. High-pressure coolant is highly recommended when machining stainless steel and exotic alloys with PVD grades to shed heat and improve chip clearance.
