PROBLEM TO BE SOLVED: To provide a rotary orbital sander including a motor having a rotary shaft with radially off-set portion. SOLUTION: A suction housing 22 is mounted to the motor 16 arround a motor shaft and connectable with a vacuum source. A sanding pad assembly 26 including a backing pad 48 having a plurality of apertures there through and an annular frame 34 having a circumferential side wall 36 including first and second circumferential edges is mounted to the radially off-set portion of the shaft. A circular back wall 42 extends from one of the circumferential edges 40, and has an opening 44 sealable with the suction housing. The other circumferential edge 38 is attached to the backing pad. This sanding pad assembly resists flapping at high rotational speeds. A sanding disk 52 having a size and a shape complimentary to that of the sanding pad and a plurality of holes 54 aligning with the apertures 50 in the sanding pad is mountable on the sanding pad. The vacuum source draws sanding waste through the aligned apertures and out the suction housing. |
