TPGH090202L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Non-Ferrous Super-Finishing
The Mitsubishi TPGH090202L-FS HTI10 is a high-precision Left-Hand (L) uncoated carbide insert. Designed for aluminum finishing and non-ferrous CNC machining, the HTI10 grade provides an ultra-sharp cutting edge that prevents material welding. The FS chipbreaker is specialized for super-finishing at light depths of cut, ensuring exceptional surface brightness and dimensional control in CNC boring operations.

HTI10 Uncoated Micro-Grain
HTI10 is a high-hardness tungsten carbide grade without coating. This allows for a sharper edge hone compared to coated inserts. It is the premier choice for boring inserts used in aluminum alloys and copper, where it resists "Built-Up Edge" (BUE) and maintains surface clarity.
FS Super-Finish Breaker
The FS chipbreaker features a high positive rake geometry. It is specifically optimized for low feed rates and shallow cutting depths, providing superior chip evacuation. This prevents long, stringy aluminum chips from wrapping around the tool or scratching the workpiece.

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.
