TaeguTec SOMT070306DP TT8020
Thermal Resistance Specialist: High-Feed Precision for Exotic Alloys
Product Overview
"Which milling insert is best for high-feed roughing in Inconel or 316 Stainless Steel without suffering from rapid thermal cracking?"
The TaeguTec SOMT070306DP TT8020 is the definitive solution for high-temperature machining. The TT8020 grade features a specialized sub-micron substrate with an advanced PVD coating that maintains hardness at extreme temperatures. Combined with the DP (General Purpose) chipbreaker, it features a reinforced land that prevents notch wear and edge chipping. This 07-size insert provides a larger depth-of-cut capacity compared to smaller series, making it ideal for large-scale high-feed roughing in Stainless Steel (ISO M) and Super Alloys (ISO S).
Key Features
Excellent resistance to thermal shock, specifically engineered for the high temperatures generated when milling exotics.
Balanced rake angle provides a strong cutting edge that withstands high axial pressure during plunging.
A larger nose radius provides enhanced edge security and better durability during heavy roughing cycles.

"Excellent on 316L" - We were burning through inserts in our pump production until we switched to TT8020. Great heat resistance.
— Marine Eng. (USA)Beste Lösung für Inconel. Die DP Geometrie ist sehr stabil bei hohen Vorschüben.
— Aero-Technik (Germany)Ottimo tagliente rinforzato. Durata eccezionale su acciai inossidabili.
— Meccanica S.p.A. (Italy)Solid reliability for 24/7 CNC production. Very consistent results.
— Osaka Heavy Industries (Japan)Frequently Asked Questions
1. Is the SOMT 07 larger than the SOMT 06?
Yes, the 07 size has a larger inscribed circle and thickness, allowing for deeper axial cuts (Ap) and higher feed rates compared to the 06 series.
2. Can I use coolant with TT8020?
Yes. TT8020 is designed to handle thermal cycling, making it compatible with wet milling, though high-pressure air is often preferred for stainless steel roughing.
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.
