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.

— 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.
