HRC55 2-Flute Solid Carbide Square End Mill Overview<\/h2>\n

This HRC55-series 2-flute solid carbide square end mill is designed for slotting, side milling, shoulder milling and selected semi-finishing operations in carbon steel, alloy steel and pre-hardened steel. Its square-end geometry supports flat-bottom features and 90\u00b0 shoulders, while the two-flute configuration provides generous chip space for full-width slotting and stable chip evacuation. Standard cutting diameters range from \u00d81 to \u00d820 mm, with AlTiN, TiSiN and application-specific coating options available according to the steel grade and machining conditions.<\/p>\n
