TaeguTec CNMG120408ET TT9080
Advanced Sub-Micron PVD Grade: The Ultimate Solution for Stainless & Heat-Resistant Alloys
Product Overview
"Which CNC insert provides the highest reliability when turning gummy stainless steel or high-temp Inconel without premature edge chipping?"
The TaeguTec CNMG120408ET TT9080 is a high-performance turning insert engineered for ISO M (Stainless Steel) and ISO S (Exotic Alloys). Utilizing the elite TT9080 PVD grade, it features a sub-micron substrate with a smooth, heat-resistant coating that prevents Built-Up Edge (BUE). The ET (Tough-Edge) chipbreaker is designed with a reinforced geometry to provide exceptional stability during medium-duty cuts, ensuring predictable tool life even in unstable machining conditions or interrupted cuts.
Key Features
A sub-micron carbide grade that offers a perfect balance of hardness and shock resistance for exotic alloys.
Engineered for "Tough" applications, the ET breaker prevents edge notch wear and controls chips effectively in high-pressure environments.
The ultra-smooth PVD coating dissipates heat quickly, reducing thermal cracking in long-duration stainless steel passes.

Verified Global Feedback
"The Best for 316L"
Turning 316L stainless shafts was a nightmare for edge chipping until we switched to the ET breaker. TT9080 is worth every cent.
— Precision Aero Parts (USA)"Exotic Alloy Specialist"
Very consistent performance on Inconel 718. The PVD coating handles the heat better than anything else in our shop.
— Fertigungstechnik GmbH (Germany)"Highly Reliable"
Predictable tool life is key for our lights-out manufacturing. TaeguTec delivers exactly what they promise.
— Industrial Precision Ltd (Japan)Frequently Asked Questions
1. Is the ET breaker suitable for finishing?
The ET (Tough Edge) breaker is designed for medium-duty turning with a focus on edge stability. For light finishing, consider the EA or PC geometries.
2. Does this grade require high-pressure coolant?
While not strictly required, high-pressure coolant is highly recommended for Stainless and Super Alloys to maximize the heat-shielding properties of the PVD coating.

Technical FAQ & Buying Guide
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.
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.
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.
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.
