TaeguTec TDJ2 TT7220
Precision 2.0mm Parting & Grooving: Optimized for High-Speed Steel Production
Product Overview
"Which 2mm parting insert provides the best tool life when running high-velocity CNC cycles in alloy steel?"
The TaeguTec TDJ2 TT7220 is the high-efficiency answer for precision parting. While the TDC series is known for its versatility, the TDJ geometry is specifically designed with a sharper cutting edge and a specialized chipbreaker that excels in reducing cutting forces. This makes it perfect for small diameter work and thin-walled parts. Paired with the TT7220 PVD coated grade, which features extreme hardness and thermal stability, this insert is a specialist for ISO P (Steel) and ISO K (Cast Iron). It allows for significantly higher cutting speeds (Vc) without sacrificing edge integrity, making it the preferred choice for mass production environments.
Core Advantages
Advanced PVD coating provides a hard, smooth surface that resists abrasive wear and flank deformation during high-speed runs.
The sharp J-type chipbreaker reduces friction and heat generation, preventing burr formation and improving surface finishes.
The narrow 2mm width ensures minimum material waste per part, a critical factor for high-volume automotive and hardware components.

"Running these at 200m/min on 4140 steel. Tool life is incredible. Much better than the universal grades."
— Robert T., USA"Perfekt für die Serienfertigung. Geringer Verschleiß bei hohen Drehzahlen."
— Dieter K., Germany"Ottima per lavorazioni ad alta velocità su ghisa. Finitura impeccabile."
— Antonio M., Italy"Efficient parting for precision shafts. The TDJ breaker reduces burrs significantly."
— Hiroshi N., Japan"Switched to TT7220 for our steel jobs. Lower cost per part due to less downtime."
— James B., UKFrequently Asked Questions
A: TT7220 is a hard grade. For heavy interrupted cuts (like hex bars), the TT9080 or TT9030 grade is generally safer due to higher toughness.
A: TDJ2 is 2.0mm wide. For deep parting of large diameters, a 3.0mm (TDC3) or 4.0mm (TDC4) insert provides better lateral stiffness.
A: It lowers the cutting pressure, which is essential for machining small, delicate parts or thin-walled components without damage.
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.
