TaeguTec DCMT11T304FG TT5100
Specialized CVD Black Grade: The Ultimate Solution for Cast Iron Finishing
Product Overview
"Which insert is most reliable for high-speed finishing in Gray and Nodular Cast Iron while maintaining maximum surface gloss?"
The TaeguTec DCMT11T304FG TT5100 is a high-performance solution tailored for ISO K (Cast Iron). The TT5100 grade is distinguished by its specialized CVD coating structure, featuring a thick Al2O3 layer that provides industry-leading resistance to abrasive flank wear and cratering. The FG (Finishing-General) chipbreaker utilizes a ground sharp edge to effectively manage chips during light finishing passes. With a 0.4mm corner radius, this insert minimizes vibration on slender workpieces while delivering the precision required for automotive and heavy industrial applications.
Key Features
Optimized for high-speed continuous cutting in cast iron, offering superior thermal stability compared to conventional gold grades.
A high-positive rake angle ensures low cutting forces, preventing work-hardening and maintaining workpiece integrity.
The ultra-hard Alumina coating prevents the abrasive particles in cast iron from degrading the cutting edge prematurely.

Global Industry Feedback
"Best in Class for GGG50"
We switched to TT5100 for our nodular iron housings. Tool life increased by 35% compared to our previous gold grade inserts.
— Cast Components Ltd (UK)"Hervorragende Standzeit"
High cutting speeds are no problem for this grade. The surface finish remains consistent from the first part to the last.
— Zerspanung Profis (Germany)"Stable and Reliable"
The FG chipbreaker is very effective. We have had no vibration issues on our internal finishing cycles.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Why is the TT5100 grade black instead of gold?
The black color indicates a specific CVD coating architecture optimized for thermal resistance in cast iron. It allows for much higher speeds without sacrificing tool life.
2. Is this insert suitable for interrupted cuts?
TT5100 is primarily for continuous cutting. For heavy interruptions in cast iron, consider a tougher grade like TT5080.
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.
