TaeguTec CNMG160612ET TT9080
The Heavy-Duty Specialist: Sub-Micron PVD Grade for Demanding Stainless & Exotic Machining
Product Overview
"Which heavy-duty insert can handle long-reach turning of austenitic stainless steel or super alloys without the edge crumbling under high heat?"
The TaeguTec CNMG160612ET TT9080 is a high-stability 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Exotics/HRSA). Utilizing the elite TT9080 PVD grade, it features a specialized sub-micron substrate and a ultra-smooth coating that minimizes built-up edge (BUE). The ET (Tough-Edge) chipbreaker provides a reinforced geometry specifically designed to prevent notch wear and edge chipping during medium-heavy passes on large workpieces.
Key Features
A fine-grained substrate providing the perfect balance of hardness and shock resistance for difficult-to-cut alloys.
Engineered with a "Tough-Edge" design to survive interrupted cuts and high-torque mechanical loads.
Increased corner strength for high feed rates and improved heat dissipation during long, heavy passes.

Verified Global Feedback
"The Solution for 316"
We were burning through inserts on 316 shafts. The TT9080 ET breaker survived the heat and interruptions perfectly.
— Precision Aero Parts (USA)"Exotic Alloy Beast"
Finally, a PVD grade that doesn't chip on Inconel. Predictable tool life is vital for us, and this delivers.
— Fertigungstechnik GmbH (Germany)"Tough as Nails"
The 1.2mm radius is a lifesaver for heavy roughing. Great vibration resistance on long-reach tools.
— Industrial Machining Ltd (Japan)Frequently Asked Questions
1. Can I use this for light finishing?
The ET breaker is built for toughness in medium-heavy passes. For high-precision light finishing, we recommend the EA or PC geometries.
2. Does this grade require high-pressure coolant?
Highly recommended. While the PVD coating is heat-resistant, high-pressure coolant further prevents built-up edge in gummy stainless steel.
