TPGH110302L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Super-Fine Non-Ferrous Finishing
The Mitsubishi TPGH110302L-FS HTI10 is an ultra-precision Left-Hand (L) uncoated carbide insert designed for mirror-finish results in non-ferrous metals. The HTI10 grade features a micro-grain structure that maintains a razor-sharp edge, essential for shearing aluminum and copper without material adhesion. The FS chipbreaker is engineered for super-finishing at extremely low depths of cut, making it a critical long-tail precision tool for high-tolerance CNC boring and turning.

HTI10 Uncoated Carbide
HTI10 is a specialized K-class micro-grain substrate. By remaining uncoated, the cutting edge remains razor-sharp, allowing it to "shear" rather than "push" gummy materials. It is the premier choice for aluminum boring where high surface brightness and zero material adhesion are required.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-high positive rake. It is specifically optimized for low feed rates and shallow cutting depths, ensuring that chips are tightly curled and ejected—preventing surface scratches in delicate CNC finishing cycles.

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.
