TaeguTec TDC2 TT8020
The Ultimate Choice for Stainless Steel Parting & Grooving
Product Overview
"Which parting insert is most reliable for preventing work hardening and chip clogging in 304/316 Stainless Steel?"
The TaeguTec TDC2 TT8020 is a high-precision, double-ended insert engineered specifically for demanding Parting and Grooving applications. Featuring the advanced TT8020 PVD Coated grade, it provides a tough substrate combined with a heat-resistant coating, making it the industry standard for ISO M (Stainless Steel) and ISO S (High-Temp Alloys). The TDC chipbreaker geometry is uniquely designed to fold chips into a "C" or "6" shape that is narrower than the groove itself, ensuring seamless evacuation and preventing surface marring or tool breakage in deep parting tasks.
Core Advantages
Highly wear-resistant PVD layer provides excellent edge stability and resists built-up edge (BUE) even in gummy materials.
TDC geometry compresses the chip width to clear the groove easily, reducing heat buildup and friction.
Two sharp cutting edges per insert offer maximum cost-efficiency without compromising tool rigidity.

Why Choose Us
Authentic TaeguTec solutions for the precision machinist. We provide factory-direct performance to ensure your production line never stops.
"Switched from a competitor to TT8020 for 316L parting. The tool life doubled. Incredible performance."
— Robert M., USA"Sehr gute Spanabfuhr bei rostfreiem Stahl. Keine verklebten Späne mehr in der Nut."
— Klaus W., Germany"Consistent quality. The TDC geometry is the best I've used for deep grooving on my CNC."
— Antonio G., Italy"Excellent for high-temp alloys. Even with Inconel 718, it holds the edge well."
— Hiroshi S., Japan"The mirror finish in the groove is exactly what our customers demand. Highly recommend."
— James B., UKFrequently Asked Questions
A: Yes, it will perform well, but TT9080 or TT8125 are generally more cost-effective for dedicated carbon steel machining.
A: The PVD coating may cause some material sticking (BUE). For Aluminum, we recommend the K10 uncoated grade.
A: No, the TaeguTec T-Clamp system is designed to fully support the insert, ensuring 100% rigidity even under heavy loads.
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.
