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.

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.
