A rotary cutting tool comprises a shank extending along an axis of rotation of the cutting tool and a fluted portion adjacent the shank, the fluted portion having an effective flute length and a plurality of peripheral cutting edges indexed about the axis of rotation. At least one of the plurality of peripheral cutting edges is formed such that a two-dimensional representation of the peripheral cutting edge in schematic development view follows a quadratic curve over the effective flute length.
