TaeguTec TDJ 4 K10
Ultra-Sharp 4.0mm Parting & Grooving Solution for Non-Ferrous High-Speed Machining
Product Overview
"Which 4mm insert is sharp enough to part large-diameter aluminum bar stock without leaving a burr or material buildup?"
The TaeguTec TDJ 4 K10 is the industrial benchmark for processing Aluminum, Brass, and Cast Iron. While coated inserts often lose their "bite" in gummy non-ferrous materials, the K10 uncoated micrograin carbide substrate allows for an incredibly sharp cutting edge that shears material rather than pushing it. The TDJ chipbreaker is specifically geometry-tuned to curl chips into a narrow "clock-spring" shape, ensuring they are evacuated instantly from 4.0mm grooves without scratching the workpiece. Its neutral (0° lead angle) orientation provides maximum strength and straightness, making it ideal for deep parting applications where tool deflection must be zero.
Core Advantages
The K10 substrate has a low affinity for non-ferrous metals, virtually eliminating Built-Up Edge (BUE) even at high temperatures.
Uncoated micrograin carbide allows for a tighter edge radius, providing the clean shearing action necessary for soft alloys.
The 4.0mm width provides increased lateral rigidity, making it the preferred choice for larger diameter parting operations.

"Switched from a coated insert to this K10 for our aluminum production. The difference in finish is night and day."
— Justin M., USA"Hervorragend für Messing. Keine Aufbauschneiden mehr."
— Stefan E., Germany"Il miglior inserto per alluminio che abbiamo mai usato."
— Antonio L., Italy"Stable parting even on 100mm aluminum bars. Very sharp."
— Takashi O., Japan"Consistent performance in cast iron. No chipping at the edge."
— George B., UKFrequently Asked Questions
A: No. Uncoated K10 will wear out almost instantly against the high temperatures and abrasiveness of Stainless. Use TT8020 for Stainless applications.
A: Yes. For best results with K10 on Aluminum, use high-pressure flood coolant or MQL to help the chipbreaker evacuate material efficiently.
A: Neutral (0° lead angle) means the cutting edge is perfectly perpendicular to the bar. This provides the straightest cut and is strongest for parting operations.
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.
