TPGH160304L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Super-Fine Finishing in Non-Ferrous Metals
The Mitsubishi TPGH160304L-FS HTI10 is a high-precision Left-Hand (L) uncoated carbide insert designed for mirror-finish results. The HTI10 grade features a specialized micro-grain tungsten carbide structure that maintains a razor-sharp edge, preventing "Built-Up Edge" (BUE) in gummy materials like Aluminum alloys and Copper. The FS chipbreaker is optimized for precision CNC boring and turning at light depths of cut, ensuring exceptional chip control and surface integrity.

HTI10 Uncoated Carbide
HTI10 is a high-hardness K-class micro-grain carbide. By remaining uncoated, Mitsubishi provides a sharper cutting edge that "shears" the material rather than rubbing. This is essential for aluminum boring and turning non-ferrous alloys where surface finish is critical.
FS Chip Control Geometry
The FS chipbreaker features a high positive rake angle. It is engineered for low feed rates and shallow depths of cut, curled chips away from the workpiece surface to prevent scratching in high-precision CNC finishing cycles.
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.
