The Original Korloy SEHT1204AFFN-X83 H01 is a premium Square Milling Insert, precision-engineered for high-speed Aluminum (N-Group) and Non-Ferrous Metal machining. Featuring the high-purity H01 Uncoated Carbide Grade, this insert undergoes a specialized mirror-polishing process on the rake face to achieve an ultra-low friction coefficient. The -X83 geometry provides an exceptionally sharp cutting edge, effectively preventing built-up edge (BUE) and ensuring a superior, high-gloss surface finish on aluminum alloys, copper, and plastics.
High-Gloss Surface Specialist: The "H01" grade is synonymous with "Mirror Finish." By eliminating the coating, the cutting edge remains much sharper than PVD-coated alternatives, allowing for effortless shearing of gummy aluminum without the material sticking to the tool.
Technical Specifications:

Machinist Tip: Why "Uncoated" H01 is better for Aluminum?
Understanding the science of aluminum milling:
Sharpness is King. Coatings (like CVD or PVD) add thickness to the edge, slightly "rounding" it. For aluminum, a rounded edge creates heat and sticking. H01 provides a razor-sharp edge for clean cuts.
Heat Barrier. While great for steel, many coatings contain Aluminum (like TiAlN), which has a chemical affinity for aluminum workpieces, actually causing more sticking.
Pro Advice: When milling at high speeds with SEHT1204AFFN-X83, ensure your chip load is sufficient to carry heat away. If you see "smearing" on the surface, increase your feed ($fz$) to ensure the tool is cutting, not rubbing.
Packaging: 10 pieces per box.

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.
