TaeguTec CCGT120408FL K10
Precision Ground & Polished Carbide Insert for High-Performance Aluminum Turning
Product Overview
"Which CNC insert is most effective for achieving mirror finishes on aluminum while handling higher feed rates without built-up edge?"
The TaeguTec CCGT120408FL K10 is a high-performance, periphery-ground 80° rhombic insert designed for elite machining of non-ferrous materials. Crafted from the K10 sub-micron uncoated carbide grade, it features an ultra-sharp cutting edge and a mirror-polished rake face. The FL chipbreaker is specifically engineered to eliminate Built-Up Edge (BUE) and provide superior chip control in Aluminum (ISO N), Copper, and Brass, even at the larger 0.8mm radius which allows for increased feed rates and edge stability.
Key Features
A specialized polishing process removes microscopic irregularities, ensuring chips flow away friction-free to prevent material adhesion.
Offers increased edge strength and allows for higher feed rates (Fn) compared to 0.4mm versions, perfect for semi-finishing to finishing.
G-class tolerance ensures extreme repeatability and dimensional accuracy, critical for Swiss-lathe and precision CNC operations.

Global Verified Reviews
"Stunning Finish"
Machined Aluminum 6061 components with Ra 0.2 surface finish. The 0.8 radius allowed us to push the feed rate without losing quality.
— Manufacturing Corp (USA)"Top Qualität für Alu"
Great tool life. The polished face is mirror-like and prevents all built-up edge. Very stable performance in our Haas lathe.
— Precision Eng (Germany)"Excellent for Brass"
Consistently sharp. Used on high-volume brass parts with zero chip clogging. Fast shipping to Italy.
— Meccanica S. (Italy)"Reliable Accuracy"
The G-class ground tolerance is perfect for our medical devices. Very high repeatability between batch changes.
— K. Tanaka (Japan)Frequently Asked Questions
1. Is the K10 grade coated?
No, K10 is an uncoated, polished carbide grade. Coating an insert for aluminum often rounds the edge and can cause material to stick; the uncoated K10 maintains the sharpest possible edge.
2. What is the difference between CCGT and CCMT?
CCGT inserts are periphery ground (G tolerance), providing much higher accuracy and a sharper edge than molded CCMT inserts.
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.
