HRC45 AlTiN-Coated Square End Mill Overview<\/h2>\n

This HRC45-series 4-flute solid carbide square end mill is designed for side milling, shoulder milling, profiling, pocket finishing and selected light slotting in carbon steel, alloy steel and tool steel. Its square-end geometry supports flat-bottom features and 90\u00b0 shoulders, while the rigid four-flute core and 35\u00b0 helix provide stable tooth engagement and consistent surface quality. The AlTiN coating supports wear and heat resistance under suitable steel-milling conditions.<\/p>\n
