TPGH160308L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
High-Performance Non-Ferrous Finishing
The Mitsubishi TPGH160308L-FS HTI10 is a heavy-duty yet precise Left-Hand (L) uncoated carbide insert. Designed for aluminum finishing and non-ferrous machining, the HTI10 grade maintains a razor-sharp edge that "shears" material to prevent surface smearing. Featuring the FS chipbreaker, this insert excels in precision CNC boring and turning, providing reliable chip control and a mirror-like surface finish on soft alloys.

HTI10 Micro-Grain Grade
HTI10 is a specialized K-class uncoated tungsten carbide. By omitting PVD/CVD coatings, the insert maintains a sharp edge hone that prevents "Built-Up Edge" (BUE). It is the premier choice for non-ferrous turning where cutting temperature is lower but material adhesion is a high risk.
FS Super-Finish Breaker
The FS chipbreaker features a high positive rake angle designed for low feed rates. It ensures that chips are curled and broken effectively even at shallow depths of cut, which is critical for maintaining surface integrity in precision CNC boring.

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.
