TPGH110302L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Super-Fine Non-Ferrous Finishing
The Mitsubishi TPGH110302L-FS HTI10 is an ultra-precision Left-Hand (L) uncoated carbide insert designed for mirror-finish results in non-ferrous metals. The HTI10 grade features a micro-grain structure that maintains a razor-sharp edge, essential for shearing aluminum and copper without material adhesion. The FS chipbreaker is engineered for super-finishing at extremely low depths of cut, making it a critical long-tail precision tool for high-tolerance CNC boring and turning.

HTI10 Uncoated Carbide
HTI10 is a specialized K-class micro-grain substrate. By remaining uncoated, the cutting edge remains razor-sharp, allowing it to "shear" rather than "push" gummy materials. It is the premier choice for aluminum boring where high surface brightness and zero material adhesion are required.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-high positive rake. It is specifically optimized for low feed rates and shallow cutting depths, ensuring that chips are tightly curled and ejected—preventing surface scratches in delicate CNC finishing cycles.
Recommended Cutting Parameters
