TPGX090208 HTI10
Mitsubishi Materials | Non-Ferrous & Light Alloy Specialist
Ultra-Sharp Finishing for Non-Ferrous Alloys
The Mitsubishi TPGX090208 HTI10 is a high-precision G-Class (Ground) uncoated carbide insert. Designed specifically for materials where "Built-Up Edge" (BUE) is a common failure, the HTI10 grade features a micro-grain substrate that maintains a razor-sharp cutting edge. This long-tail non-ferrous tool is the industry standard for CNC boring and finishing of Aluminum alloys, Copper, and Brass, delivering a clean shear and superior surface integrity.

HTI10 Carbide Mastery
The HTI10 grade is an uncoated micro-grain carbide. While coatings are useful for heat resistance in steel, they often round the cutting edge. By remaining uncoated, HTI10 provides a surgical sharpness that prevents "gumming" in aluminum and results in much lower cutting forces, making it ideal for thin-walled components.
0.8mm Radius Advantage
With an 0.8mm nose radius, this insert provides increased edge strength compared to the 0.2mm or 0.4mm variants. This allows for higher feed rates and better durability in rough-to-finish non-ferrous operations where productivity is the goal.

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.
