TaeguTec DCMT070208FG TT9225
Versatile PVD Grade: The Ultimate Precision Finisher for Steel & Stainless Alloys
Product Overview
"Which insert is most effective for maintaining tight tolerances and a smooth finish in both carbon steel and stainless steel components?"
The TaeguTec DCMT070208FG TT9225 is a multi-purpose powerhouse designed for ISO P (Steel) and ISO M (Stainless Steel) finishing. The TT9225 grade features a specialized PVD coating with ultra-fine grain technology that provides high hardness and resistance to flank wear. The FG (Finishing-General) chipbreaker is ground to a high-positive rake angle, which significantly reduces cutting heat and friction. With a reinforced 0.8mm corner radius, this insert offers enhanced edge strength over traditional finishing tools, making it ideal for stable, high-quality production of automotive and medical precision parts.
Key Features
Advanced multi-layer coating provides a smooth surface to prevent material welding, critical for stainless steel finishing.
A sharp, high-positive cutting edge reduces tool pressure, ensuring excellent surface gloss and dimensional stability.
Increased corner radius provides better feed rates and longer life in stable applications compared to 0.4mm variants.

Global Industry Feedback
"Versatile and Durable"
We use TT9225 for both our steel and stainless production. The tool life is very consistent across both materials—saved us a lot on inventory.
— Precision Machining Co. (USA)"Hervorragende Oberfläche"
The FG chipbreaker is excellent for finishing passes. No vibration and the surface gloss is impressive.
— Zerspanung Profis (Germany)"Solid Stainless Performance"
The smooth PVD finish really helps with built-up edge in 304 stainless. Good dimensional accuracy throughout the batch.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Is the TT9225 grade suitable for interrupted cuts?
Yes. The PVD coating and substrate used in TT9225 offer better toughness compared to CVD grades, making it more reliable for light interruptions.
2. What is the benefit of the 0.8mm radius over 0.4mm?
The 0.8mm radius (08) offers higher edge strength and can handle higher feed rates, though it requires a slightly more stable setup to prevent vibration in finishing.
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.
