TPGX110304 HTI10
Mitsubishi Materials | Non-Ferrous & Light Alloy Precision Specialist
High-Speed Non-Ferrous Finishing
The Mitsubishi TPGX110304 HTI10 is a premium G-Class (Precision Ground) uncoated carbide insert. Unlike coated tools that can round the cutting edge, the HTI10 micro-grain substrate provides an atomically sharp edge, which is vital for shearing soft, "gummy" materials. This long-tail non-ferrous insert is the industry standard for CNC boring and finishing of Aluminum alloys, Copper, and Brass, ensuring zero material welding and a mirror-like surface.

HTI10 Grade Superiority
The HTI10 grade is an uncoated, micro-grain tungsten carbide (ISO K10 range). It is specifically formulated to provide extreme hardness and sharpness. In aluminum turning, it prevents the common issue of material "gumming" or sticking to the tool edge, which is the key to maintaining tight tolerances in CNC boring operations.
TPGX Ground Sharpness
As a G-class insert, the TPGX geometry is fully ground. This allows for a massive 11° positive relief angle and a razor-sharp edge that standard molded inserts cannot achieve. This geometry reduces cutting force and heat, making it perfect for thin-walled non-ferrous parts.

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.
