ABSTRACT:
A stud driver and remover for large diameter studs includes an improved construction that enables the stud driver and remover to quickly remove large diameter studs that previously had to be removed usually by drilling. The improved stud driver and remover for large diameter studs 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. A radius of each of a plurality of cams formed in a core of the tool is dependent on the size of at least one of an inner diameter of the main ring, a diameter of one of the rolls and a radius of the stud to be driven and removed. The cooperation between the cams and the core is modified to accept an increased variance in stud size.
