This Eastwood bead roller has a 1/6hp 120v electric motor which makes it much easier to work large or long pieces without the help of friends. With a typical manual roller you need to crank the handle and manipulate the work piece at the same time, but not with our power roller. The reversible, infinitely variable, foot pedal control lets you control the speed and direction of the rollers, even while both hands are on the work. The 36 inch throat means you can roll a bead right down the center of a 6 foot wide panel if you want to. This professional strength bead roller will form beads, joggles and bends in steel sheet up to 16 gauge, and aluminum up to 14 gauge. This unit comes complete with dies to make a variety of shape beads and bends as well, for unlimited uses, right out of the box. The shaft size for optional die sets is 3/4" diameter.
