TPGX110304L HTI10
Mitsubishi Materials | Left-Hand Non-Ferrous Precision Specialist
Sharp Edge Technology for Gummy Materials
The Mitsubishi TPGX110304L HTI10 is a high-precision Left-Hand (L), G-Class (Ground) uncoated carbide insert. Designed specifically for non-ferrous materials where "Built-Up Edge" (BUE) ruins surface integrity, 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.

HTI10 Uncoated Advantage
HTI10 is a micro-grain uncoated carbide. While coatings provide heat protection for steel, they often "round" the edge. HTI10 keeps an atomically sharp periphery, preventing aluminum from "sticking" to the tool. This ensures the TPGX ground sharpness delivers a pristine, glossy finish on light alloys.
Left-Hand Precision
The "L" (Left-Hand) designation is crucial for specific machine setups. As a G-class insert, the dimensions are held to sub-micron tolerances, making it perfect for high-speed finishing where repeatability and minimal tool pressure are required.
