TaeguTec TDC4 TT9080
Maximum Edge Security: The 4.0mm Solution for Severe Interrupted Cuts
Product Overview
"Which 4mm parting insert is tough enough to handle heavy interrupted cuts in alloy steel without chipping the cutting edge?"
The TaeguTec TDC4 TT9080 is engineered for "worst-case scenario" machining. When dealing with large diameter Hex Bars, cross-holes, or unstable workholding, standard grades often fail due to mechanical shock. The TT9080 PVD grade features a specialized high-toughness substrate that acts as a shock absorber. Combined with the 4.0mm TDC chipbreaker, which uses a concave geometry to compress chips narrower than the slot, this insert provides unrivaled stability. It is the industrial choice for Steel (ISO P) and Stainless Steel (ISO M) where process security is more critical than pure cutting speed.
Core Advantages
Unique multi-layer PVD coating designed to prevent crack propagation during heavy interrupted machining cycles.
The 4mm width offers maximum lateral support, drastically reducing vibration in deep grooves or large radial parting.
The TDC breaker folds chips into a "C" shape narrower than 4mm, eliminating sidewall friction and surface damage.

"Parting 75mm hex bar was a nightmare until we switched to TDC4 TT9080. No more chipped edges."
— David H., USA"Extrem zähe Wendeschneidplatte. Perfekt für unterbrochene Schnitte."
— Klaus W., Germany"La rigidità del 4mm unita alla tenacità del grado TT9080 è imbattibile su acciai legati."
— Marco V., Italy"Great tool for roughing applications. Reliable and tough."
— Sato T., Japan"If you have an unstable setup, this is the insurance policy you need for your CNC."
— Ryan G., UKFrequently Asked Questions
A: TT9080 is optimized for toughness. For high-speed continuous cuts in stable steel, TT7220 will offer better wear resistance.
A: The 4.0mm width provides significantly more lateral stability than 2mm or 3mm inserts, making it the choice for heavy-duty production.
A: Yes, all TDC inserts are double-ended, effectively doubling your tool life per insert.
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.
