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
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.
