TaeguTec TDC2 TT8020
The Ultimate Choice for Stainless Steel Parting & Grooving
Product Overview
"Which parting insert is most reliable for preventing work hardening and chip clogging in 304/316 Stainless Steel?"
The TaeguTec TDC2 TT8020 is a high-precision, double-ended insert engineered specifically for demanding Parting and Grooving applications. Featuring the advanced TT8020 PVD Coated grade, it provides a tough substrate combined with a heat-resistant coating, making it the industry standard for ISO M (Stainless Steel) and ISO S (High-Temp Alloys). The TDC chipbreaker geometry is uniquely designed to fold chips into a "C" or "6" shape that is narrower than the groove itself, ensuring seamless evacuation and preventing surface marring or tool breakage in deep parting tasks.
Core Advantages
Highly wear-resistant PVD layer provides excellent edge stability and resists built-up edge (BUE) even in gummy materials.
TDC geometry compresses the chip width to clear the groove easily, reducing heat buildup and friction.
Two sharp cutting edges per insert offer maximum cost-efficiency without compromising tool rigidity.

"Switched from a competitor to TT8020 for 316L parting. The tool life doubled. Incredible performance."
— Robert M., USA"Sehr gute Spanabfuhr bei rostfreiem Stahl. Keine verklebten Späne mehr in der Nut."
— Klaus W., Germany"Consistent quality. The TDC geometry is the best I've used for deep grooving on my CNC."
— Antonio G., Italy"Excellent for high-temp alloys. Even with Inconel 718, it holds the edge well."
— Hiroshi S., Japan"The mirror finish in the groove is exactly what our customers demand. Highly recommend."
— James B., UKFrequently Asked Questions
A: Yes, it will perform well, but TT9080 or TT8125 are generally more cost-effective for dedicated carbon steel machining.
A: The PVD coating may cause some material sticking (BUE). For Aluminum, we recommend the K10 uncoated grade.
A: No, the TaeguTec T-Clamp system is designed to fully support the insert, ensuring 100% rigidity even under heavy loads.

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.
