TaeguTec DNMG150404EA TT9080
Mastering Exotics: High-Performance PVD Finishing for Aerospace & Medical Alloys
Product Overview
"Which insert grade provides the sharpest edge and highest thermal stability for finishing passes on work-hardening stainless steels and titanium?"
The TaeguTec DNMG150404EA TT9080 is the definitive answer for ISO M (Stainless) and ISO S (Exotics) finishing. Utilizing the TT9080 PVD grade, this insert features a sub-micron grain carbide substrate that provides the necessary edge toughness to prevent micro-chipping. The EA (Exotic Alloy) chipbreaker is engineered with an ultra-sharp geometry to "slice" through material rather than "plow," significantly reducing heat generation and surface work-hardening. This results in superior dimensional accuracy and a mirror-like finish on critical components.
Key Features
AlTiN PVD coating provides elite oxidation resistance and hardness at high temperatures, essential for exotic alloy turning.
The Exotic Alloy chipbreaker features a highly positive rake to minimize cutting forces and prevent built-up edge (BUE).
Ideal for final finishing passes where low radial force is required to maintain tight tolerances on slim parts.

Verified Global Feedback
"Flawless on Titanium"
We use EA TT9080 for medical grade titanium. The surface finish is incredible and the edge stays sharp through the entire batch.
— Med-Tech Solutions (USA)"Top für Inconel"
Outstanding resistance to notch wear in Inconel 718. The chip control is the best we've seen for finishing exotics.
— Aero-Präzision GmbH (Germany)"Ottimo Controllo Truciolo"
Great chip control on 304 stainless. No more bird-nesting on our finishing passes. Very stable grade.
— Meccanica di Precisione (Italy)"Reliable Performance"
Excellent dimensional stability. We can run long finishing cycles without worrying about tool wear compensation.
— Sato Aerospace (Japan)Frequently Asked Questions
1. Is TT9080 better than CVD for stainless steel?
For finishing passes and exotic alloys, the PVD TT9080 is superior due to its sharper edge and better resistance to thermal shock. CVD is better for high-speed continuous roughing.
2. Can I use the EA chipbreaker for roughing?
No. The EA chipbreaker is an ultra-positive geometry specifically optimized for finishing to light medium cutting. For heavy roughing, please see the EM or ET series.

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.
