TPGH160304L-FS HTI10
Mitsubishi Materials | Uncoated Micro-Grain Carbide (Left-Hand)
Super-Fine Finishing in Non-Ferrous Metals
The Mitsubishi TPGH160304L-FS HTI10 is a high-precision Left-Hand (L) uncoated carbide insert designed for mirror-finish results. The HTI10 grade features a specialized micro-grain tungsten carbide structure that maintains a razor-sharp edge, preventing "Built-Up Edge" (BUE) in gummy materials like Aluminum alloys and Copper. The FS chipbreaker is optimized for precision CNC boring and turning at light depths of cut, ensuring exceptional chip control and surface integrity.

HTI10 Uncoated Carbide
HTI10 is a high-hardness K-class micro-grain carbide. By remaining uncoated, Mitsubishi provides a sharper cutting edge that "shears" the material rather than rubbing. This is essential for aluminum boring and turning non-ferrous alloys where surface finish is critical.
FS Chip Control Geometry
The FS chipbreaker features a high positive rake angle. It is engineered for low feed rates and shallow depths of cut, curled chips away from the workpiece surface to prevent scratching in high-precision CNC finishing cycles.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Aluminum Alloys (Si < 12%) | 200 - 800 m/min | 0.05 - 0.20 mm/rev | 0.1 - 1.5 mm |
| Copper & Brass | 150 - 500 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.2 mm |
REQUIRED LEFT-HAND HOLDERS
Optimized for use with Left-Hand (L) tool paths. Pair with standard STFPL 16 or STGPL 16 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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
