TaeguTec TDC3 TT7220
Precision 3.0mm Parting Solution for Steel & Cast Iron Production
Product Overview
"Which 3mm parting insert offers the best thermal stability and wear resistance for high-speed CNC steel turning?"
The TaeguTec TDC3 TT7220 is a high-performance, double-ended 3mm insert engineered for Parting and Grooving in high-productivity environments. Utilizing the TT7220 PVD Coated grade—a sub-micron substrate known for its extreme hardness and thermal resistance—this tool excels in ISO P (Steel) and ISO K (Cast Iron). The TDC chipbreaker features a specialized concave geometry that folds the chip narrower than the 3.0mm cut, ensuring seamless evacuation in deep grooving and preventing damage to the finished sidewalls.
Core Advantages
Provides superior resistance to plastic deformation and flank wear at high cutting speeds, specifically in alloyed steels.
The 3mm width provides exceptional lateral rigidity, reducing vibration and "walking" during deep radial entries.
Two fully functional cutting edges per insert reduce tooling costs and machine downtime for tool changes.

"Switched from a 2mm to this 3mm TDC3 for our steel bar work. The stability is night and day. Much cleaner cuts."
— Mark R., USA"Hervorragende Verschleißfestigkeit bei legiertem Stahl. Der TT7220 hält deutlich länger."
— Stefan M., Germany"Ottimo controllo del truciolo. Anche in canali profondi non abbiamo mai avuto intasamenti."
— Luca B., Italy"Genuine quality. Works perfectly on our Okuma machines for batch production."
— Yoshi T., Japan"Best 3mm parting insert we've used for cast iron blocks. Predictable life every time."
— Alan G., UKFrequently Asked Questions
A: While possible, it is optimized for Steel. For 300-series Stainless, the TT8020 or TT9030 grades are significantly more durable.
A: TDC3 is more robust. It handles larger diameters and heavier feeds better than TDC2, which is more focused on material savings.
A: No, the TDC series is specifically designed for the TaeguTec T-Clamp mounting system for maximum process security.

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.
