SOGT12T308PEFR-JP HTI10
Mitsubishi Materials | Non-Ferrous & Aluminum High-Speed Specialist
The Mitsubishi SOGT12T308PEFR-JP HTI10 is a high-precision uncoated carbide milling insert designed for high-speed machining of aluminum alloys, copper, and non-ferrous materials. Utilizing the HTI10 micro-grain substrate and the ultra-sharp JP chipbreaker, this insert prevents chip welding and built-up edge (BUE), delivering a mirror-like surface finish on critical aerospace and automotive components.

HTI10: Uncoated Super-Micro Grain
HTI10 is Mitsubishi's premium uncoated carbide grade. It features a super-micro grain structure that maintains an incredibly sharp cutting edge. Unlike coated grades where the coating might round off the edge, HTI10 stays razor-sharp, which is essential for machining aluminum to prevent material adhesion and heat buildup.
JP Polished Chipbreaker
The JP chipbreaker is a "Polished" geometry designed specifically for non-ferrous metals. It features a high rake angle and a mirror-polished top face to facilitate rapid chip evacuation. This minimizes the risk of scratched surface finishes caused by chip re-cutting in high-speed CNC milling environments.

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.
