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.

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.
