TaeguTec CNMG120412PC TT9080
Precision Finishing in Tough Materials: Sub-Micron PVD Grade for Exotic Alloys
Product Overview
"Which turning insert grade offers the best chip control and thermal stability when finishing gummy stainless steels or heat-resistant super alloys?"
The TaeguTec CNMG120412PC TT9080 is the definitive solution for high-precision finishing in ISO M (Stainless Steel) and ISO S (Super Alloys). The TT9080 PVD grade features an ultra-fine sub-micron substrate coated with advanced thermal protection layers to prevent chemical wear and built-up edge (BUE). The PC (Positive Finishing) chipbreaker geometry is ground to a sharp edge, providing low cutting resistance while the 1.2mm radius offers significant edge strength for consistent production runs.
Key Features
Excellent toughness combined with a thin, smooth PVD coating that prevents chip welding on sticky materials.
Positive rake angle design reduces work hardening of the workpiece surface, critical for aerospace alloys.
The larger corner radius dissipates heat more effectively and allows for higher feed rates without compromising finish.

Verified Global Feedback
"Perfect for Stainless 316"
We turn 316L pump parts and built-up edge was always a struggle. The TT9080 grade solved it. Incredible finish.
— Precision Fluidics (Germany)"Reliable on Titanium"
Used these for finishing aerospace bushings. The 1.2 radius provides great heat dissipation and the edge stays sharp far longer than competitors.
— Aero-Machining (USA)"Consistent Quality"
Very predictable tool life across our production batches. The PC breaker is ground beautifully for low depth-of-cut passes.
— High-Spec Parts (Italy)Frequently Asked Questions
1. Is TT9080 suitable for dry machining?
While highly heat resistant, for finishing Stainless and Super Alloys, we strongly recommend high-pressure coolant to ensure optimal chip evacuation and surface quality.
2. Can I use the PC breaker for roughing?
No, the PC (Positive Finishing) breaker is designed for low-force finishing. For heavier roughing, consider MT or RT chipbreaker geometries.

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.
