TaeguTec SCMT120408-PC TT9080
Advanced PVD Finishing Solution for Heat-Resistant Super Alloys
Product Overview
"Which CNC insert is most reliable for achieving high-gloss finishes on Inconel 718 and Titanium Grade 5 without suffering from notch wear?"
The TaeguTec SCMT120408-PC TT9080 is the industrial answer for precision finishing in ISO S (HRSA) and ISO M (Stainless Steel). The TT9080 grade is defined by its sub-micron substrate and a specialized PVD coating that excels in environments where heat dissipation is poor. The PC (Precision/Positive) chipbreaker geometry is designed to "shear" rather than "tear" the material, significantly reducing work hardening in gummy stainless steels. With a 0.8mm nose radius, this insert provides robust edge stability for long finishing cycles, ensuring dimensional accuracy and world-class surface Ra values.
Key Features
A dense PVD coating with ultra-high oxidation resistance, ideal for the high-temp zones of aerospace alloy machining.
Minimizes radial cutting forces, crucial for maintaining tolerances on thin-walled or slender workpieces.
The 0.8mm radius (RE) balances sharpness with toughness to prevent premature micro-chipping in interrupted cuts.

| TT9225 | Advanced CVD | Stainless Power: Better for general turning and heavy interrupted cuts in stainless. |
Why Choose TaeguTec?
TaeguTec is a global pioneer in tungsten carbide technology, and the SCMT120408-PC TT9080 is a testament to our industrial expertise in super alloy machining. We understand that "Exotic" materials like Inconel and Titanium pose unique challenges—thermal conductivity is low, and the material tends to "work harden" instantly. Our TT9080 grade is designed with a nanostructured PVD coating that acts as a thermal shield, protecting the sharp cutting edge from deformation. The PC chipbreaker ensures that chips are broken and evacuated efficiently, preventing heat from transferring back into the workpiece. When you choose TaeguTec, you invest in predictable tool life and world-class surface Ra quality.
Verified Global Feedback
"Excellence in Inconel"
We were burning through edges on Inconel 718 turbine hubs. TT9080 provides the most stable tool life we've found in 10 years.
— Aero-Precision Components (USA)"Hervorragende Oberfläche"
The PC geometry is sharp enough for medical Titanium Grade 5 parts. No burrs and a mirror-like finish every time.
— Medical Zerspanung GmbH (Germany)"Ottima per Acciaio Inox"
Excellent performance in AISI 316. The chip breaker handles gummy chips perfectly. Very consistent batch-to-batch.
— Meccanica di Precisione (Italy)"Reliable for High-Heat"
Great for our turbine disc finishing passes. The coating resists notch wear better than other PVD grades we've tested.
— Sato Heavy Industries (Japan)Frequently Asked Questions
1. Is TT9080 better than TT5080 for Titanium?
Yes. TT9080 is the premier grade for finishing in Titanium and Super Alloys due to its superior heat resistance and edge stability.
2. Can I use this for medium turning?
The PC chipbreaker is specialized for finishing. For heavier medium turning, consider the MT chipbreaker for better chip management at higher depths of cut.

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.
