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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
