TaeguTec TDC2-6R TT7220
Precision 6° Lead Angle Parting for Burr-Free Results
Product Overview
"Which parting insert is most effective for eliminating the central pip and burrs on steel tube components?"
The TaeguTec TDC2-6R TT7220 is a high-performance, double-ended parting insert featuring a specialized 6-degree right-hand lead angle. This geometry is critical for precision parting-off where a flat face on the component is required, as it directs the burr toward the bar stock. Utilizing the TT7220 PVD Coated grade—a sub-micron substrate with enhanced thermal stability—this insert excels in ISO P (Steel) and ISO K (Cast Iron). The TDC chipbreaker ensures chips are curled into a width narrower than the groove, preventing sidewall friction and ensuring a mirror-like surface finish.
Core Advantages
Reduces or eliminates the "pip" on the center of the parted part, significantly reducing secondary deburring operations.
A tough, wear-resistant coating optimized for high-speed steel machining, providing long and predictable tool life.
Two sharp cutting edges per insert double your machining capacity per component without sacrificing rigidity.

"The 6R angle is perfect for my 304 steel tubes. Virtually zero burr on the finished part."
— James K., USA"Der TT7220 ist hervorragend bei der Stahlbearbeitung. Sehr lange Standzeit."
— Gunther R., Germany"TDC chip control is top-notch. No more long, tangled chips in my machine sump."
— Fabio V., Italy"Genuine TaeguTec. Stabilized my parting process on gray iron castings."
— Hiroaki O., Japan"Fast delivery and the 2mm width saves me quite a bit of material on large batch runs."
— Simon P., UKFrequently Asked Questions
A: It ensures the parting "pip" remains on the bar stock, leaving a clean, flat surface on the parted component.
A: Yes, but keep in mind the lead angle. For standard square grooving, a 0° lead insert (TDC 2) is typically preferred.
A: While the PVD coating handles heat well, high-pressure coolant is always recommended for parting to flush chips out of the narrow groove.
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.
