TaeguTec DNMG150408EM TT9080
PVD Precision: The Ultimate Solution for Stainless Steel and Exotic Alloys
Product Overview
"Which insert grade provides the best resistance to work hardening and notch wear when machining 304 or 316 stainless steel?"
The TaeguTec DNMG150408EM TT9080 is engineered for ISO M (Stainless) and ISO S (Exotics). Unlike standard CVD grades, the TT9080 grade utilizes a specialized PVD AlTiN coating over a high-toughness sub-micron substrate. This combination is critical for resisting the thermal shocks inherent in stainless steel turning. The EM (Exotic Medium) chipbreaker features a sharp, positive rake angle that slices through gummy materials, significantly reducing cutting temperature and preventing the built-up edge (BUE) that typically degrades surface quality in exotic alloys.
Key Features
Advanced PVD coating with ultra-fine grain carbide for maximum edge toughness and wear resistance.
Positive cutting action designed to minimize work hardening in stainless steels and Inconel.
Prevents smearing and built-up edge for aerospace-grade precision and mirror-like Ra values.

Verified Global Feedback
"The Stainless Killer"
We struggled with notch wear on 316L for years. TT9080 doubled our tool life and the EM chipbreaker keeps the chips short and manageable.
— Aerospace Machining Group (USA)"Exzellente Standzeit"
Very stable performance in Duplex steel. The PVD coating is extremely tough and doesn't flake even under heavy load.
— Müller Präzision (Germany)"Ottima Finitura"
Outstanding surface finish on medical titanium. The EM geometry is sharp enough to avoid any smearing.
— Tecnologie Mediche (Italy)"Solid for Inconel"
Handles the heat of HRSA materials very well. Predictable wear patterns help us plan our lights-out shifts.
— Sato Heavy Industries (Japan)Frequently Asked Questions
1. Is PVD TT9080 better than CVD grades for stainless?
PVD TT9080 is better for toughness and sharpness, which is ideal for gummy stainless and exotics. CVD is generally preferred for high-speed continuous cutting.
2. Can I use this for Titanium?
Yes. The EM chipbreaker and TT9080 grade are excellent for ISO S materials like Titanium and Nickel-based alloys.

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.
