TaeguTec DNMG150608EM TT9080
Reinforced 6.35mm Thickness: The Heavy-Duty PVD Specialist for Exotic Alloys
Product Overview
"Which reinforced insert provides the best edge toughness and thermal shock resistance when machining aerospace-grade stainless steel?"
The TaeguTec DNMG150608EM TT9080 is a high-performance solution for ISO M (Stainless) and ISO S (Exotics). By utilizing the 1506 series (6.35mm thickness), this insert offers significantly better rigidity and heat dissipation than standard 4.76mm versions. The TT9080 grade features a specialized PVD AlTiN coating over a sub-micron substrate, designed to resist notch wear and flaking in work-hardening materials. The EM (Exotic Medium) chipbreaker is engineered with a sharp, positive rake that prevents built-up edge (BUE) and reduces cutting forces in gummy materials like 316L stainless and Inconel.
Key Features
A 6.35mm thickness profile provides the mechanical strength needed for stable, heavy-duty exotic alloy turning.
AlTiN coating ensures elite thermal stability and edge protection against chemical wear in high-nickel alloys.
Sharp cutting action minimizes work-hardening and ensures smooth chip flow in aerospace materials.

Verified Global Feedback
"Perfect for Inconel"
We use the reinforced 1506 series for our turbine shafts. TT9080 grade handles the heat perfectly and the EM geometry keeps the chips under control.
— AeroSpace Components Ltd. (USA)"Top für Edelstahl"
Outstanding performance on 316 stainless. The PVD coating is very tough, no flaking even after long runs.
— Präzisionstechnik Schmidt (Germany)"Grande Affidabilità"
Very reliable for medical-grade titanium. The surface finish is consistently excellent thanks to the sharp EM edge.
— Tecnologie Mediche (Italy)"Solid and Sharp"
Excellent edge toughness. Predictable wear patterns help us keep our CNC machines running 24/7.
— Sato Precision (Japan)Frequently Asked Questions
1. Why is the 1506 thickness better for exotics?
The 6.35mm thickness provides better heat absorption and mechanical stability, which is vital when cutting high-temperature alloys that generate extreme heat.
2. Can TT9080 be used for titanium?
Yes. The PVD TT9080 grade is specifically optimized for both Stainless (ISO M) and Super Alloys like Titanium (ISO S).
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.
