TPGH080204L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Non-Ferrous Precision Overview
The Mitsubishi TPGH080204L-FS HTI10 is a specialized Left-Hand (L) uncoated carbide insert engineered for super-finishing non-ferrous materials. The HTI10 grade is a micro-grain tungsten carbide known for its extreme hardness and edge sharpness. Combined with the FS chipbreaker, this tool excels at CNC boring and turning of aluminum alloys, brass, and copper, providing a mirror-like surface finish by eliminating material welding on the cutting edge.

HTI10 Uncoated Carbide
HTI10 is a K-class uncoated carbide grade. Unlike coated tools, the uncoated surface allows for a razor-sharp edge that is essential for cutting gummy materials like Aluminum or Pure Copper. It offers high wear resistance and prevents the "built-up edge" common in non-ferrous turning.
FS "Super-Finish" Breaker
The FS chipbreaker is an ultra-high positive finisher. It is designed to curl and break chips at very low feed rates and shallow depths of cut. This is critical for chip evacuation in blind holes or small-bore boring where chip wrapping can damage the part.
Recommended Cutting Parameters
| Workpiece Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys (Si < 12%) | 200 - 600 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.0 mm |
| Copper & Brass | 150 - 400 m/min | 0.05 - 0.12 mm/rev | 0.1 - 0.8 mm |
REQUIRED LEFT-HAND HOLDERS

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.
