TaeguTec DCMT11T308FG TT8115
High-Efficiency CVD Gold Grade: Optimized for Abrasive Material Finishing
Product Overview
"Which turning insert offers the best wear resistance for high-speed finishing in Gray and Ductile Cast Iron?"
The TaeguTec DCMT11T308FG TT8115 is a specialized solution for ISO K (Cast Iron) and stable ISO P (Steel). The TT8115 grade utilizes a thick CVD coating with a multi-layered alumina (Al2O3) structure, providing a formidable barrier against heat and abrasive wear. The FG (Finishing-General) chipbreaker is ground to a high-precision sharp edge, which significantly reduces cutting forces and eliminates surface scratching. With a reinforced 0.8mm corner radius, this insert balances elite surface finish with the edge strength required for continuous high-speed CNC turning.
Key Features
Thick CVD Al2O3 coating allows for maximum spindle speeds while protecting the carbide substrate from cratering.
Ground chipbreaker design ensures stable chip breaking at low depths of cut, even in materials prone to stringing.
Superior resistance to plastic deformation, ensuring dimensional accuracy throughout the tool's entire lifespan.

Global Industry Feedback
"Reliable for High Speeds"
We increased our spindle speed by 15% on our cast iron batch. The TT8115 grade didn't flinch—excellent tool life.
— CastPro Precision (USA)"Top Oberflächengüte"
Consistent wear patterns and very clean cuts. The 0.8mm radius gives great strength for high-volume jobs.
— Zerspanung Profis (Germany)"Solid Cast Iron Finishing"
The FG breaker produces perfect chips. No vibration issues at all during long finishing passes.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Is CVD coating better than PVD for Cast Iron?
Yes. CVD coatings like TT8115 are thicker and offer significantly better thermal resistance, which is critical for handling the abrasive nature of cast iron at high speeds.
2. Can I use this for Stainless Steel?
No. For stainless steel, we recommend PVD-coated grades like TT5080. CVD grades can be too brittle for the gummy nature of stainless steel.
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.
