Abstract
A stud driver and remover for studs having non-grip areas includes an improved construction that enables the stud driver and remover to drive and remove studs without damaging a non-grip portion of the stud. The improved stud driver and remover includes five drive rolls, and increased ratio between the cross-sectional areas of the stud and the drive rolls. The stud driver and remover also includes an increased roll length and decreased included angle which allows the roll to penetrate more deeply into the stud. Each of a plurality of cams formed in a core of the tool is provided with a recess to accommodate one of the rolls. These recesses allow the tool to be placed on a stud having a non-grip area such as a flange or threaded area and to drive and remove the stud without damaging the non-grip area.
