TaeguTec DNMG150608PC TT8115
Reinforced 6.35mm Thickness: The High-Speed Precision Leader for Steel
Product Overview
"Which reinforced insert provides the best thermal stability for high-velocity finishing in alloy steel without compromising edge sharpness?"
The TaeguTec DNMG150608PC TT8115 is an industrial-grade solution for high-productivity ISO P (Steel) turning. By utilizing the 1506 series (6.35mm thickness), this insert offers significantly higher rigidity and vibration dampening than standard 1504 models. The TT8115 grade features a thick CVD Alumina (Al2O3) coating that acts as a superior thermal barrier, allowing your CNC machines to operate at maximum surface speeds. Combined with the PC (Positive Finishing) chipbreaker, it delivers a sharp, positive cutting action that minimizes heat generation at the workpiece while ensuring elite chip evacuation and mirror-quality surface finishes.
Key Features
A 6.35mm thickness provides exceptional mechanical support and thermal absorption for high-speed passes.
CVD Al2O3 layer ensures incredible crater wear resistance even at the extreme temperatures of continuous dry machining.
Positive finishing chipbreaker designed to lower cutting forces, preventing vibration and ensuring tight tolerances.

Verified Global Feedback
"Maximum Throughput"
We increased our Vc by 25% with the TT8115. The 1506 thickness makes a massive difference in stability compared to standard inserts.
— Precision Dynamics Inc. (USA)"Exzellente Finishqualität"
Outstanding surface Ra. The PC chipbreaker is very sharp, reducing noise and heat even on tougher alloy steels.
— Fertigungstechnik Schmidt (Germany)"Affidabilità Superiore"
The most reliable insert for high-speed finishing. We run 3 shifts and the tool life is incredibly predictable.
— Meccanica di Precisione Rossi (Italy)"Elite Precision"
A perfect match for our high-precision CNC lathes. Sharp, fast, and stable. Highly recommended for steel finishing.
— Industrial Tooling Corp (Japan)Frequently Asked Questions
1. Can the TT8115 grade handle interrupted cuts?
The TT8115 is optimized for continuous high-speed passes. For interrupted cuts, we recommend the TT8125 or TT8135 for better shock resistance.
2. Does this 1506 insert fit a standard 1504 holder?
The IC is the same, but because the 1506 is 6.35mm thick (vs 4.76mm), you must ensure your holder’s pocket and shim are designed to accommodate the extra height.
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.
