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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
