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.

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.
