TPGH090202L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Non-Ferrous Super-Finishing
The Mitsubishi TPGH090202L-FS HTI10 is a high-precision Left-Hand (L) uncoated carbide insert. Designed for aluminum finishing and non-ferrous CNC machining, the HTI10 grade provides an ultra-sharp cutting edge that prevents material welding. The FS chipbreaker is specialized for super-finishing at light depths of cut, ensuring exceptional surface brightness and dimensional control in CNC boring operations.

HTI10 Uncoated Micro-Grain
HTI10 is a high-hardness tungsten carbide grade without coating. This allows for a sharper edge hone compared to coated inserts. It is the premier choice for boring inserts used in aluminum alloys and copper, where it resists "Built-Up Edge" (BUE) and maintains surface clarity.
FS Super-Finish Breaker
The FS chipbreaker features a high positive rake geometry. It is specifically optimized for low feed rates and shallow cutting depths, providing superior chip evacuation. This prevents long, stringy aluminum chips from wrapping around the tool or scratching the workpiece.
Recommended Cutting Parameters
