TaeguTec TDJ2 TT8020
The Professional 2.0mm Choice for Stainless Steel and Exotic Alloys
Product Overview
"Which 2mm insert is most effective for parting 316 stainless steel without causing excessive heat or built-up edge?"
The TaeguTec TDJ2 TT8020 is a high-performance specialist for ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys). Machining these materials often leads to work-hardening and thermal cracking. The TT8020 PVD grade features a sub-micron substrate with a high-aluminum content coating that remains stable at extreme temperatures. Coupled with the TDJ sharp chipbreaker, it generates lower cutting forces and creates narrow, tightly curled chips that evacuate the groove instantly. This combination ensures that your 2.0mm parting operations remain precise and your surface finish remains flawless.
Core Advantages
Advanced multi-layer PVD coating designed to resist heat-induced chemical wear and notch wear common in stainless machining.
The "J-Type" breaker is significantly sharper than standard "C-Type" breakers, reducing the drag that causes work-hardening.
Folded chip design prevents sidewall scratching, ensuring high-quality surface integrity on the cut face.

"Best insert for 316L. The edge stays sharp and I get way more parts per edge than with universal grades."
— Aaron B., USA"Hervorragend für Edelstahl. Sehr gute Standzeit und saubere Schnittkanten."
— Lukas M., Germany"Perfetto per titanio. Il grado TT8020 resiste molto bene al calore."
— Giovanni R., Italy"High precision finish on small diameter stainless parts. Reliable."
— Takashi Y., Japan"My go-to for Duplex. Lower heat and no built-up edge."
— Paul K., UKFrequently Asked Questions
A: For stainless steel and super alloys, high-pressure coolant is strongly recommended to prevent work-hardening and to extend tool life.
A: Yes. TT8020 is specifically engineered for high-temperature strength, which is vital when parting exotic heat-resistant alloys.
A: While sharp, the coating on TT8020 might cause some chip adhesion. For Aluminum, the uncoated K10 grade (TDJ2 K10) is a better choice.
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.
