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 |
