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.
Recommended Cutting Parameters
