An improved honing head construction having one or more honing stone assemblies arranged around a rotatable mandrel body that includes a central body portion and pair of opposed end plate forming together a scroll feed up assembly operable for radially moving the honing assemblies during rotation of the mandrel for such purposes as adjusting the honing diameter, honing pressure and material removal rate, the scroll feed up assembly comprising helical scroll feed grooves located adjacent to each opposite end of the mandrel body and arranged to be positioned as mirror images of one another, each honing assembly having a pair of pin members arranged in axially aligned pairs and extending radially inwardly into radial extending bores in mandrel body, each of the pin members having at least one tooth cooperatively engageable with one of the respective helical grooves such that all of the honing assemblies move radially in concert when the end plates are rotated relative to the central body portion.
