TPGX090204 HTI10
Mitsubishi Materials | Non-Ferrous & Aluminum Finishing Specialist
Precision Non-Ferrous Machining
The Mitsubishi TPGX090204 HTI10 is a high-precision G-Class (Ground) uncoated carbide insert. Unlike coated grades that can dull the cutting edge, the HTI10 grade maintains an ultra-sharp periphery, which is essential for shearing soft materials like Aluminum, Copper, and Brass. This long-tail non-ferrous tool is the premier choice for CNC boring and finishing where preventing "Built-Up Edge" (BUE) and achieving high dimensional accuracy are critical.

HTI10 Uncoated Carbide
HTI10 is a micro-grain uncoated carbide substrate. Unlike TiN or AlTiN coatings which "round" the cutting edge slightly, HTI10 allows for an atomically sharp edge. This is vital for aluminum machining, as it prevents the material from sticking to the tool, ensuring a clear cut and a high-quality surface finish.
TPGX "G-Class" Precision
The "G" signifies that the insert is fully ground on all faces. In boring bar applications, this ground finish is critical for maintaining concentricity and preventing chatter, especially when working with high-RPM spindle speeds common in aluminum turning.

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.
