TaeguTec TDJ 2-6R TT8020
Precision 6° Lead Angle Parting: The Professional Choice for Clean Stainless Steel Cut-Offs
Product Overview
"Which 2mm parting insert provides a clean finish with minimal burrs on 304/316 stainless steel bars?"
The TaeguTec TDJ 2-6R TT8020 is the go-to solution for high-precision CNC parting operations. Featuring a 6-degree Right-Hand lead angle, this insert is specifically designed to minimize the "pip" or "nub" left on the workpiece after cut-off, significantly reducing or eliminating secondary facing operations. The TT8020 PVD coated grade is a dedicated specialist for ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys). It offers exceptional resistance to heat and notch wear, while the sharp TDJ chipbreaker ensures smooth chip flow and reduced cutting pressure, preventing work-hardening in sensitive alloys.
Core Advantages
The 6-degree angle provides a superior balance between reducing parting nubs and maintaining the structural stability of the cutting edge.
A high-aluminum PVD coating designed to withstand the intense thermal loads of machining Stainless Steel and Inconel.
The sharp positive geometry is engineered to slice through "gummy" materials, ensuring a clean cut and excellent surface finish.

"The 6-degree angle is perfect. It leaves almost zero pip on our 316 parts without the instability of the 15-degree inserts."
— Jeremy P., USA"Hervorragende Standzeit in Edelstahl. Sehr zuverlässige Wendeschneidplatte."
— Bernd S., Germany"Grado TT8020 fantastico per Inconel. Meno calore e finitura ottima."
— Luca F., Italy"Consistent performance in our Swiss lathes. Good chip control."
— Akira K., Japan"No more manual deburring. The 6R angle is exactly what we needed."
— Steven G., UKFrequently Asked Questions
A: Choose 6R when you need to eliminate the cut-off pip on the part being parted off. Neutral inserts are better for general grooving or when parting very large diameters where deflection is a concern.
A: No. It is specifically designed to fit the TaeguTec T-Clamp toolholder system.
A: "R" stands for Right-Hand. This refers to the direction of the lead angle relative to the tool orientation.
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.
