TaeguTec TDJ 4 TT9080
Heavy-Duty 4.0mm Universal Insert for Reliable Parting & Deep Grooving
Product Overview
"Which 4mm parting insert provides the highest reliability for interrupted cuts on large diameter steel bars?"
The TaeguTec TDJ 4 TT9080 is engineered for machinists who demand zero-failure performance. When dealing with large diameters or interrupted surfaces (like hex or square stock), the tool faces significant mechanical shock. The TT9080 grade features a specialized sub-micron PVD-coated substrate that excels in absorbing these impacts while maintaining a sharp cutting edge. The TDJ chipbreaker is designed with a high-positive rake that narrows the chip width, ensuring that the 4.0mm chips do not weld to the groove side-walls, even during deep radial operations in Stainless Steel and Alloy Steel.
Core Advantages
TT9080 is a multi-material grade that maximizes tool life in Steel, Stainless, and Cast Iron, streamlining your inventory.
The tough substrate prevents premature edge chipping, making it the safest choice for unstable setups or rough surfaces.
The 4.0mm neutral geometry ensures balanced cutting forces, reducing chatter and improving surface finish on large parts.

"The TT9080 is the only grade that doesn't explode when we part off 4140 hex bar. Rock solid."
— Mike R., USA"Hervorragende Standzeit bei Edelstahl. Die Spankontrolle bei 4mm ist perfekt."
— Dieter K., Germany"Ottima affidabilità. Usiamo questo inserto per tutta la nostra produzione di alberi in acciaio."
— Stefano V., Italy"Very stable in deep grooving. Reduced our tool breakage costs significantly."
— Kenji Y., Japan"Universal indeed. Works on everything we throw at it. Excellent value."
— Arthur P., UKFrequently Asked Questions
A: While it can cut Aluminum, the TT9080 grade is PVD coated for toughness in harder metals. For Aluminum, we recommend the K10 uncoated grade for a sharper edge and zero material welding.
A: No. The TDJ series is specifically for radial grooving and parting. For turning and grooving, consider the TDC or TDT series.
A: Yes, as a neutral (0°) insert, it will leave a small center pip. For a flat-face finish on the part, you would need a lead-angle version (e.g., 6R/15R).
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
