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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
