TaeguTec CNMG120412EM TT9080
Maximum Edge Strength: High-Toughness PVD Grade for Demanding Alloy Turning
Product Overview
"Which carbide insert grade is most reliable for high-feed medium machining in Stainless Steel without losing the cutting edge to heat?"
The TaeguTec CNMG120412EM TT9080 is the industrial answer to machining ISO M (Stainless Steel) and ISO S (Heat Resistant Super Alloys). The TT9080 PVD grade is built on a sub-micron substrate that excels in preventing notch wear and thermal cracking. The EM (Medium-Duty) chipbreaker is engineered for stable chip control, while the robust 1.2mm corner radius allows for significantly higher feed rates and enhanced tool life in aggressive CNC turning applications.
Key Features
Advanced coating technology provides a smooth surface that resists Built-Up Edge (BUE) in gummy materials like 316L.
Designed for medium-duty versatility, ensuring consistent chip breaking even at varying depths of cut.
The large corner radius offers exceptional edge reinforcement and heat dissipation for high-productivity machining.

Verified Global Feedback
"Top Tier for Inconel"
We turn a lot of Inconel 625. The TT9080 grade with the 1.2 radius is the only insert we've found that can handle the heat at higher feed rates.
— Precision Aerospace (USA)"Excellent on 316 Stainless"
Finally, an insert that doesn't develop built-up edge on 316L. The EM chipbreaker leaves a mirror finish even in medium-heavy passes.
— Machining Solutions GmbH (Germany)"Very Tough Edge"
Incredibly consistent. We run these on our night shifts; predictable tool life makes it easy to automate our production schedule.
— Industrial Parts (Japan)Frequently Asked Questions
1. Is the EM breaker suitable for heavy roughing?
The EM (Medium-Duty) breaker is optimized for medium machining. For ultra-heavy roughing of stainless steel, we recommend the ET or MT geometries.
2. Does this grade require coolant?
While highly heat resistant, for finishing and medium turning of Stainless Steel and Super Alloys, high-pressure coolant is strongly recommended to maximize surface quality.

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.
