TaeguTec TDC3 TT7220
Precision 3.0mm Parting Solution for Steel & Cast Iron Production
Product Overview
"Which 3mm parting insert offers the best thermal stability and wear resistance for high-speed CNC steel turning?"
The TaeguTec TDC3 TT7220 is a high-performance, double-ended 3mm insert engineered for Parting and Grooving in high-productivity environments. Utilizing the TT7220 PVD Coated grade—a sub-micron substrate known for its extreme hardness and thermal resistance—this tool excels in ISO P (Steel) and ISO K (Cast Iron). The TDC chipbreaker features a specialized concave geometry that folds the chip narrower than the 3.0mm cut, ensuring seamless evacuation in deep grooving and preventing damage to the finished sidewalls.
Core Advantages
Provides superior resistance to plastic deformation and flank wear at high cutting speeds, specifically in alloyed steels.
The 3mm width provides exceptional lateral rigidity, reducing vibration and "walking" during deep radial entries.
Two fully functional cutting edges per insert reduce tooling costs and machine downtime for tool changes.

"Switched from a 2mm to this 3mm TDC3 for our steel bar work. The stability is night and day. Much cleaner cuts."
— Mark R., USA"Hervorragende Verschleißfestigkeit bei legiertem Stahl. Der TT7220 hält deutlich länger."
— Stefan M., Germany"Ottimo controllo del truciolo. Anche in canali profondi non abbiamo mai avuto intasamenti."
— Luca B., Italy"Genuine quality. Works perfectly on our Okuma machines for batch production."
— Yoshi T., Japan"Best 3mm parting insert we've used for cast iron blocks. Predictable life every time."
— Alan G., UKFrequently Asked Questions
A: While possible, it is optimized for Steel. For 300-series Stainless, the TT8020 or TT9030 grades are significantly more durable.
A: TDC3 is more robust. It handles larger diameters and heavier feeds better than TDC2, which is more focused on material savings.
A: No, the TDC series is specifically designed for the TaeguTec T-Clamp mounting system for maximum process security.
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.
