High Speed Steel (HSS) end mills remain a workhorse choice for general-purpose milling, offering good toughness and value for shops running lower speeds or softer materials like mild steel, aluminum, and plastics. Our HSS selection includes Square End and Ball End styles, Double End versions, Metric sizing, HSS Tapered End Mills, Spiral Flute designs, High Speed Steel Roughers, HSS Bridgeport End Mills, Corner Rounding End Mills, Dovetail Cutters, and T-Slot Cutters.

HSS end mills are more forgiving of less rigid setups and older equipment compared to carbide, and their lower cost per tool makes them practical for jobs with heavy tool wear or frequent changeovers. All HSS end mills are USA manufactured and typically in stock for same-day shipping with a 97% fill rate.
