TaeguTec TDJ 3 TT8020
Precision 3.0mm Neutral Parting for Stainless Steel & High-Temp Alloys
Product Overview
"Which 3mm parting insert can handle the heat of 316L stainless steel without the edge collapsing?"
The TaeguTec TDJ 3 TT8020 is the premier choice for challenging materials. Machining Stainless Steel and Inconel generates immense heat at the cutting zone, which often leads to rapid flank wear or plastic deformation of the tool. The TT8020 grade features a specialized high-aluminum content PVD coating that acts as a thermal barrier, maintaining hardness even at extreme temperatures. The TDJ chipbreaker is designed with a sharp positive rake angle to slice through gummy materials, significantly reducing cutting forces and preventing the work-hardening of the workpiece.
Core Advantages
TT8020 grade is engineered to resist thermal cracking and oxidation, making it perfect for high-pressure coolant applications.
The TDJ geometry curls "gummy" stainless chips into tight, manageable scrolls, preventing bird-nesting on the spindle.
Sharp cutting edge ensures clean shearing, reducing secondary deburring time on critical aerospace and medical parts.

"TT8020 is the only grade that lasts in our 316 stainless production. Excellent heat resistance."
— Mark S., USA"Hervorragende Standzeit bei rostfreiem Stahl. Sehr zu empfehlen."
— Jürgen B., Germany"Il miglior inserto per acciaio inossidabile. Taglio pulito e senza sbavature."
— Paolo R., Italy"Consistent performance in Titanium. Good tool life for the price."
— Hiroshi K., Japan"Chip control is miles ahead of our previous supplier. No more bird-nesting."
— Thomas L., UKFrequently Asked Questions
A: Yes. Its neutral (0° lead angle) design makes it an excellent choice for both parting and external radial grooving with flat bottoms.
A: Absolutely. In fact, TT8020 performs significantly better with high-pressure coolant as it helps evacuate chips even faster in deep grooves.
A: While it will cut Carbon Steel, it is not optimized for it. For Carbon Steel (ISO P), we recommend the TT9080 or TT7220 grades for better cost-per-part efficiency.

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.
