TPGH080204L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Non-Ferrous Precision Overview
The Mitsubishi TPGH080204L-FS HTI10 is a specialized Left-Hand (L) uncoated carbide insert engineered for super-finishing non-ferrous materials. The HTI10 grade is a micro-grain tungsten carbide known for its extreme hardness and edge sharpness. Combined with the FS chipbreaker, this tool excels at CNC boring and turning of aluminum alloys, brass, and copper, providing a mirror-like surface finish by eliminating material welding on the cutting edge.

HTI10 Uncoated Carbide
HTI10 is a K-class uncoated carbide grade. Unlike coated tools, the uncoated surface allows for a razor-sharp edge that is essential for cutting gummy materials like Aluminum or Pure Copper. It offers high wear resistance and prevents the "built-up edge" common in non-ferrous turning.
FS "Super-Finish" Breaker
The FS chipbreaker is an ultra-high positive finisher. It is designed to curl and break chips at very low feed rates and shallow depths of cut. This is critical for chip evacuation in blind holes or small-bore boring where chip wrapping can damage the part.
Recommended Cutting Parameters
| Workpiece Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys (Si < 12%) | 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
Optimized for use with Left-Hand (L) tool paths. Use with STFPL or STGPL boring bars and tool holders.

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.
