TaeguTec SCMT09T308-FG TT5080
Precision Finishing Specialist: Advanced PVD Coating for Stainless Steel
Product Overview
"Which CNC insert provides the most stable chip control and longest tool life when finishing gummy stainless steel components at high precision?"
The TaeguTec SCMT09T308-FG TT5080 is the ultimate industrial choice for fine finishing ISO M (Stainless Steel) and ISO P (Steel). The TT5080 grade is defined by its nanostructured PVD coating which offers exceptional resistance to built-up edge (BUE)—the primary enemy of surface finish in stainless machining. The FG (Fine Geometry) chipbreaker is meticulously designed with a sharp cutting edge and a specific rake angle that "ploughs" through the material, ensuring that even at very small depths of cut, chips are broken effectively and evacuated without marring the workpiece surface.
Key Features
High-aluminum content AlTiN coating ensures extreme heat resistance and superior edge toughness for interrupted cuts.
Specialized for finishing depths of cut (0.5mm - 1.5mm), preventing the "stringy" chips common in austenitic stainless steel.
The ultra-smooth surface of the TT5080 grade reduces friction, significantly lowering the risk of material welding to the tool tip.

| TT5080 | PVD (Thin) | The Sharp Choice: Best for finishing and low cutting forces. |
| TT9225 | CVD (Thick) | The Tough Choice: Best for high speed and medium turning. |
Why Choose TaeguTec?
TaeguTec is a global pioneer in metalworking technology, and the SCMT09T308-FG TT5080 is a testament to our industrial expertise in finishing. We understand that in precision CNC machining, the difference between a perfect part and scrap is measured in microns. Our TT5080 grade is designed with an AlTiN PVD coating that acts as a thermal shield, protecting the sharp cutting edge from deformation. The FG geometry ensures that chips are broken and evacuated quickly, preventing heat transfer into the workpiece. When you choose TaeguTec, you invest in predictable tool life and world-class surface Ra quality.
Verified Global Feedback
"Perfect for 316 Stainless"
We were struggling with stringy chips on our medical parts. The FG geometry solved it instantly. Surface finish is mirror-like.
— Precision MedTech (USA)"Spitzenqualität"
Outstanding tool life in alloy steel finishing. The TT5080 grade handles the heat much better than other PVD brands we've tested.
— CNC-Zerspanung GmbH (Germany)"Ottima stabilità"
Dimensional stability is key for us. This insert holds tolerances over long batches without needing constant offsets.
— Meccanica di Precisione (Italy)"Very Sharp"
Very sharp edge, great for low-vibration finishing. Wish the price was lower, but you get what you pay for in quality.
— Sato Precision (Japan)Frequently Asked Questions
1. What is the difference between FG and PC chipbreakers?
The FG (Fine Geometry) is specifically for lighter finishing depths (typically under 1.5mm), while the PC (Precision) chipbreaker handles a slightly broader finishing to semi-finishing range.
2. Can I use this grade for machining Aluminum?
While it can cut aluminum, it's not optimal. For non-ferrous materials, we recommend uncoated, polished grades for better chip flow and lower adhesion.

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.
