TaeguTec TDJ 3 TT9080
The Universal 3.0mm Parting Powerhouse for Interrupted Cuts & Tough Alloys
Product Overview
"Which 3mm parting insert is reliable enough to handle interrupted cuts on hex bars without chipping the edge?"
The TaeguTec TDJ 3 TT9080 is the go-to "safety first" insert for CNC machinists. When machining conditions are less than perfect—such as long overhangs, interrupted cuts (hex or square stock), or varying material hardness—the TT9080 PVD grade provides a unique sub-micron substrate that absorbs impact where other inserts fail. The TDJ chipbreaker geometry features a balanced edge profile that manages chip width effectively, ensuring that the 3.0mm groove remains clear of debris. This neutral design (0° lead angle) is the industrial standard for achieving flat-bottom grooves and high-strength parting in Alloy Steel and Stainless Steel.
Core Advantages
TT9080 is TaeguTec’s toughest PVD grade, specifically engineered to resist chipping during heavy interruptions or unstable setups.
A true universal grade that excels in Steel (P), Stainless (M), and Cast Iron (K), reducing the need for massive tool inventories.
The TDJ geometry prevents chip clogging in deep grooves by narrowing the chip for effortless evacuation.

"Best universal grade. I use TT9080 for everything from mild steel to stainless. Never chips."
— Robert J., USA"Perfekt für Sechskantmaterial. Sehr zähe Sorte."
— Hans W., Germany"Ottima per tagli interrotti. Molto affidabile in produzione."
— Luca B., Italy"Very versatile. Good surface finish even on harder alloys."
— Kenji S., Japan"Reliable tool life. We use it for high-volume automotive parts."
— David H., UKFrequently Asked Questions
A: Yes. The TT9080 grade is designed specifically for the mechanical shocks associated with square, hex, and interrupted parting.
A: The TDJ geometry is primarily for radial grooving and parting. For side-turning, we recommend the TDC or TDT series inserts.
A: Neutral inserts like the TDJ 3 provide the most stable cut and are required if you need a flat bottom on a groove or maximum strength during the parting operation.
