TaeguTec CCMT060204FG TT8125
Advanced PVD Coated Carbide for High-Stability Stainless Steel Finishing
Product Overview
"Which insert is most reliable for achieving high-precision surface finishes on gummy stainless steels while preventing built-up edge?"
The TaeguTec CCMT060204FG TT8125 is a high-performance 80° rhombic turning insert engineered specifically for ISO M (Stainless Steel) and ISO P (Steel) finishing. Utilizing the cutting-edge TT8125 PVD coating, this grade features a tough sub-micron substrate and a smooth coating layer that effectively resists adhesive wear and thermal cracking. The FG chipbreaker (Finishing Geometry) is designed with a sharp rake angle to reduce cutting resistance, ensuring excellent chip evacuation and superior surface integrity during light-duty finishing passes.
Key Features
The FG geometry combined with PVD technology maintains a razor-sharp edge to slice through stainless steel without burr formation.
TT8125 is designed to prevent coating delamination, providing consistent tool life even in varying cutting conditions.
Excellent chip control at low feed rates (fn) prevents the long, stringy chips typically associated with 300-series stainless steels.

Verified Global Feedback
"Perfect for Medical Components"
Using the TT8125 on 316L. The surface finish is exceptional and the tool stays sharp much longer than my previous PVD grade.
— Precision Med-Tech (USA)"Hervorragend bei Edelstahl"
Very stable dimensions across 500-part batches. The FG chipbreaker is a lifesaver for long-chip control issues.
— Feinmechanik GmbH (Germany)"Molto Affidabile"
Great price-to-performance ratio. TaeguTec always delivers on quality for our lathe department.

1. What is the difference between TT8125 and TT9080?
TT8125 is a specialized grade specifically optimized for Stainless Steel finishing stability. TT9080 is a more versatile "multi-purpose" grade for Steel, Stainless, and Alloys.
2. Can I use this for boring small holes?
Yes, the 80° Rhombic CCMT 06 shape is ideal for internal boring. Ensure you use a compatible SCLCR 06 boring bar.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
