TaeguTec TDJ 2-6RS TT8020
Precision 6° Lead Angle & Ultra-Sharp Edge for Burr-Free Parting
Product Overview
"Which 2.0mm parting insert is sharp enough to cut thin-walled stainless tubes without leaving a burr or a center pip?"
The TaeguTec TDJ 2-6RS TT8020 is a specialized solution for precision Swiss-style and CNC lathe parting. The 6-degree lead angle reduces the parting "pip" to an absolute minimum, while the "S" (Sharp) designation indicates an un-honed, razor-sharp edge that slices through gummy materials instead of pushing them. This is critical for Stainless Steel (ISO M) and High-Temp Alloys (ISO S) where friction causes work-hardening. The TT8020 PVD grade provides the necessary heat resistance to maintain that sharp edge throughout long production cycles, ensuring dimensional accuracy and a mirror-like finish.
Core Advantages
The sharpest possible edge for parting operations, designed to minimize cutting forces and prevent burr formation on the workpiece.
Offers the benefits of pip-reduction while maintaining better straightness and tool life than steeper 15° lead angles.
Multi-layer PVD coating provides exceptional chemical and thermal stability in tough alloys like 316L and Inconel.

Why Choose Our TDJ 2-6RS
We provide genuine TaeguTec products to ensure you get the exact edge geometry required for high-precision parting. The 6RS configuration is a specialized tool that eliminates the hidden costs of manual deburring and scrapped parts.
"The sharp edge on the 6RS is perfect for our medical grade stainless parts. No burrs at all."
— Jeffrey L., USA"Einfach klasse für die Kleinteilfertigung. Der Anschnitt ist extrem sauber."
— Stefan H., Germany"Perfetto per acciaio inox. L'inserto 6RS riduce drasticamente il lavoro manuale."
— Antonio V., Italy"Great stability. Use this for all our Swiss lathe parting operations."
— Yuki T., Japan"The best 2mm insert we've used for austenitic stainless. TT8020 grade is very durable."
— James C., UKFrequently Asked Questions
A: Because of the Sharp (S) edge, it is more prone to chipping than the standard honed versions. For interrupted cuts, we recommend the TDJ 2-6R (Honed) in TT9080 grade.
A: The 6RS offers better directional stability. If a 15RS causes your tool to drift or deflect, the 6RS will provide a straighter cut while still reducing the center pip.
A: Yes. The sharp edge and TT8020 grade are excellent for preventing the heat build-up and sticking common with Titanium parting.
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.
