The Micro 100 RME-021-2 is a new, solid subminiature carbide end mill from Micro 100's "Super Carbide" line, manufactured in the USA. Decoding the MPN: "RME" = Reduced shank (tapered neck) square-end (flat bottom) end mill, "021" = 0.021 in (0.533 mm) cutting diameter, "2" = 2 flutes. The reduced/tapered neck profile — clearly visible in the photo — minimizes shank interference and allows reach into deeper pockets while maintaining the rigidity of the larger-diameter shank body. This micro-geometry tool is designed for precision milling of fine features in aluminum, brass, copper, plastics, and other non-ferrous or soft materials on CNC machining centers and micro-milling machines; the 2-flute configuration optimizes chip clearance in these materials. The tool ships in Micro 100's standard orange-capped plastic protective vial, and the uncoated bright carbide finish is confirmed by the appearance in the product image.
