TaeguTec SOMT09T308DP TT8020
The Professional Choice for Exotic Alloys: High-Feed Stability & Thermal Resistance
Product Overview
"Which milling insert provides the best tool life for high-feed roughing in 316L Stainless Steel or Titanium Grade 5?"
The TaeguTec SOMT09T308DP TT8020 is a premier industrial solution designed for the ChaseFeed series. The TT8020 grade is a specialized sub-micron substrate with an advanced PVD coating that excels in environments where heat dissipation is a major challenge. The DP (General Purpose) chipbreaker features a reinforced cutting land and optimized rake angle to reduce vibration during aggressive axial feeds. This 09-size insert is significantly more robust than smaller series, making it the "gold standard" for large-volume metal removal in ISO M (Stainless) and ISO S (Super Alloys).
Key Features
Specifically engineered to resist thermal cracking and chemical wear in gummy and heat-resistant materials.
Reinforced edge design prevents micro-chipping during high-impact entry and interrupted cuts.
The 0.8mm corner radius provides maximum edge strength for the highest possible feed-per-tooth (fz).

Why Choose TaeguTec?
TaeguTec's ChaseFeed series is world-renowned for defining the high-feed milling category. The SOMT09T308DP TT8020 is built for industrial-scale CNC production where reliability is non-negotiable. By choosing TaeguTec, you invest in high-feed technology that maximizes your Metal Removal Rate (MRR) while minimizing spindle load. Our advanced PVD coatings ensure your tools stay in the cut longer, even in the most abrasive and heat-intensive conditions.
"Heat Shield Grade" - We were failing every other insert in Inconel. TT8020 doubled our tool life instantly.
— Aerospace Parts (USA)Beste Standzeit bei rostfreiem Stahl. Die 09er Größe ist extrem stabil.
— Präzisionsfertigung (Germany)Ottima per la fresatura ad alto avanzamento. Molto affidabile.
— Meccanica S.p.A. (Italy)Aggressive feed rates achieved with zero edge chipping. Top quality.
— Heavy Industries (Japan)Frequently Asked Questions
1. Is the SOMT 09 compatible with SOMT 06 cutters?
No, the 09 size is larger and thicker. It requires dedicated **MFH 09** cutter bodies to ensure proper seating.
2. Should I use coolant with TT8020?
Yes, TT8020 handles thermal shock well. For stainless steel, high-pressure coolant is recommended to help with chip evacuation.
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.
