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
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys (Si < 12%) | 200 - 800 m/min | 0.05 - 0.20 mm/rev | 0.1 - 1.5 mm |
| Copper & Brass | 150 - 500 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.2 mm |
REQUIRED LEFT-HAND HOLDERS
