The 31-482 oscillating edge sander is equipped with a powerful 1-1/2 HP dual voltage motor that is ready to power through even the toughest jobs. The 1/4 in. belt oscillation ensures full use of the belt, which reduces uneven wear and helps reduce the potential for sanding lines while prolonging belt life. The large belt surface allows for edge and surface sanding, as well as the additional option of contour and inside curve sanding using the cast iron table attachment around the drum on the motor side of the machine.
