The Ultimate "Problem Solver": Maximum Security for Heavy Interrupted Milling
Product Overview
"Which high-feed milling insert is toughest for heavy interrupted cuts and unstable workpieces in stainless steel?"
The TaeguTec SOMT08T306DP TT9300 is engineered for survival in the most hostile machining environments. The TT9300 grade utilizes a shock-resistant sub-micron substrate with a multi-layered PVD coating, specifically designed to withstand mechanical impact and thermal shock. Its DP (General Purpose) geometry features a significantly reinforced cutting land, providing a "heavy-duty" edge that prevents chipping where other inserts fail. This 08-size insert offers the maximum thickness in the ChaseFeed range, making it the premier choice for large-volume roughing in Stainless Steel (ISO M) and Steel (ISO P) under interrupted or unstable conditions.
Key Features
The industry's leading grade for interrupted milling, preventing micro-chipping during high-impact entry and exit.
A specialized land angle provides unmatched edge security during aggressive high-feed ramping and plunging.
The 08-size body (3.97mm thickness) ensures zero deflection under extreme axial pressure.

— Heavy Industries (Japan)Frequently Asked Questions
1. When should I choose TT9300 over TT9080?
Choose TT9300 for safety: heavy interruptions, unstable clamping, or weldments. Choose TT9080 for speed: stable cuts and higher Vc.
2. Can I use coolant with the SOMT 08 TT9300?
Yes, PVD grades are coolant-friendly. However, for maximum tool life in stainless, dry milling with air cooling is often superior to prevent thermal fatigue.
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.
