TaeguTec DCGT11T308FL K10
Engineered for ISO N: High-Feed Razor-Sharp Solution for Aluminum & Non-Ferrous Alloys
Product Overview
"Which precision insert offers the best surface finish on aluminum while maintaining high feed rates and preventing edge build-up?"
The TaeguTec DCGT11T308FL K10 is a specialized turning insert designed for superior performance in ISO N (Non-Ferrous) materials. Built using the high-purity K10 Uncoated Carbide grade, this insert maintains a razor-sharp peripheral ground edge that is essential for preventing "Built-Up Edge" (BUE) in gummy metals like Aluminum, Copper, and Brass. The FL (Finishing-Light) chipbreaker, combined with a 0.8mm radius, allows for incredibly clean cuts and high-gloss surface results even under varied feed conditions.
Key Features
A micro-grain uncoated tungsten carbide that offers extreme hardness and chemical inertness to resist material welding.
A ground and polished rake face ensures chips flow effortlessly, preventing surface scratching and heat concentration.
The 0.8mm corner radius provides superior edge strength and better Ra finish values at higher feed rates compared to 0.2/0.4mm versions.

Why Choose TaeguTec?
TaeguTec, as a premium brand within the IMC Group, is a world leader in non-ferrous machining science. Our DCGT K10 series is engineered specifically to combat the chemical "welding" of gummy metals to the tool edge. By maintaining a pure, uncoated carbide substrate, we deliver the sharpest edge integrity possible—a feat that coated inserts cannot match without rounding the edge. When your work requires mirror surface finishes and absolute dimensional stability, professional machinists choose TaeguTec.
Verified Global Feedback
"Superb Finish at High Feed"
The 0.8mm radius on these K10 inserts is a game changer for our aluminum housing production. We pushed the feed rate and the Ra finish stayed consistent.
— Precision Engineering Ltd (UK)"Razor Sharp"
Incredible for brass and pure copper. The FL breaker is perfect for managing those long, gummy chips. Outstanding life for uncoated carbide.
— Precision Fabrica (Italy)"Great Performance"
Very stable dimensions across large batches of aluminum 6061. Highly recommended for any finishing work.
— CNC Solutions (Australia)Frequently Asked Questions
1. Why is K10 better than coated grades for aluminum?
Uncoated K10 provides a significantly sharper edge. Coatings round the edge slightly, which causes aluminum to "smear" rather than cut cleanly.
2. Can I use these for Stainless Steel or Cast Iron?
No. Uncoated carbide will suffer from rapid diffusion wear in ferrous materials. Use PVD coated grades like TT9020 for stainless applications.
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.
