TPGH090204L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Precision Non-Ferrous Finishing
The Mitsubishi TPGH090204L-FS HTI10 is a specialized Left-Hand (L) uncoated carbide insert engineered for super-finishing of non-ferrous metals. The HTI10 grade is a micro-grain tungsten carbide known for its extreme sharpness and resistance to material adhesion. Paired with the FS chipbreaker, this tool is the premier choice for CNC boring and turning of aluminum alloys, copper, and plastics, delivering a mirror-like surface finish.

HTI10 Uncoated Carbide
HTI10 is a specialized K-class micro-grain substrate. By remaining uncoated, the insert maintains a razor-sharp edge hone that is vital for shearing gummy materials. It provides high hardness and excellent wear resistance in boring inserts for aluminum and non-ferrous turning.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-high positive rake angle. Optimized for low feed rates and shallow cutting depths, it forces chips to curl and break quickly, preventing long, stringy chips that can wrap around the workpiece in CNC boring operations.
Recommended Cutting Parameters
| Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys | 200 - 600 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.0 mm |
| Copper & Brass | 150 - 400 m/min | 0.05 - 0.12 mm/rev | 0.1 - 0.8 mm |
REQUIRED LEFT-HAND HOLDERS
Designed for Left-Hand (L) tool paths. Optimized for use with standard STFPL or STGPL tool holders and boring bars.

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.
