TaeguTec TDXU 4E-0.4 TT9030
Professional 4.0mm Multi-Directional Solution for Stainless & Exotic Materials
Product Overview
"Which 4mm insert offers the highest tool life when side-turning 316 Stainless Steel and Inconel?"
The TaeguTec TDXU 4E-0.4 TT9030 is the definitive answer for challenging ISO M and ISO S materials. As a centerpiece of the T-Clamp family, this 4.0mm width insert features the XU chipbreaker, specifically designed for Multi-Directional Turning. Unlike standard grooving inserts, the TDXU handles longitudinal turning forces with ease. The TT9030 grade utilizes a specialized PVD coating over a tough sub-micron substrate, preventing notch wear and built-up edge—the two biggest enemies of stainless steel machining.
Core Performance Advantages
Superior thermal shock resistance and edge toughness tailored for the "gummy" nature of stainless steels and high-temp alloys.
Optimized for radial plunging and axial turning, allowing for complex profiling with a single turret station.
The 0.4mm corner radius provides the ideal balance of edge strength for roughing and surface finish for finishing.

Why Machinists Choose TT9030
Machining stainless steel is about managing heat and friction. The TDXU 4E-0.4 TT9030 is built to keep the heat at the chip, not the edge, ensuring predictable wear and reduced downtime in your CNC operations.
"Switched from a competitor to TT9030 for our 316L parts. Tool life doubled. The 4mm width is very rigid."

— Roberto M., Italy"Highly predictable tool life in lights-out manufacturing. Reliable performance."
— Takashi O., JapanFrequently Asked Questions
A: Yes, the XU geometry is a multi-directional chipbreaker designed for radial plunging and side-turning.
A: For stainless steel and alloys, high-pressure coolant is highly recommended to prevent work hardening and heat buildup.
A: For axial turning, we recommend a maximum depth (Ap) of 2.0mm - 2.5mm depending on material hardness.
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.
