TaeguTec SOMT08T306DP TT9300
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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
