TPGH090204L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Precision Non-Ferrous Finishing
The Mitsubishi TPGH090204L-FS HTI10 is a specialized Left-Hand (L) uncoated carbide insert engineered for super-finishing of non-ferrous metals. The HTI10 grade is a micro-grain tungsten carbide known for its extreme sharpness and resistance to material adhesion. Paired with the FS chipbreaker, this tool is the premier choice for CNC boring and turning of aluminum alloys, copper, and plastics, delivering a mirror-like surface finish.

HTI10 Uncoated Carbide
HTI10 is a specialized K-class micro-grain substrate. By remaining uncoated, the insert maintains a razor-sharp edge hone that is vital for shearing gummy materials. It provides high hardness and excellent wear resistance in boring inserts for aluminum and non-ferrous turning.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-high positive rake angle. Optimized for low feed rates and shallow cutting depths, it forces chips to curl and break quickly, preventing long, stringy chips that can wrap around the workpiece in CNC boring operations.
Recommended Cutting Parameters

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.
