The T-Rex Planetary machine is a light weight, extremely portable planetary polishing machine with the most affordable price. It is a rugged, planetary powered tool designed to produce a flat, swirl free finish on counter tops, floors and steps. The planetary polishing tool can be used to grind, hone, polish and clean concrete, terrazzo, marble and granite surfaces with diamond abrasives. This is a true planetary gear driven tool. The 10" platform turns at a lower rate than the higher rotational speed of the 4 inch platens. This combination provides the optimal speed for diamond polishing, producing a perfect finish 5 times faster than a single head polisher. The unit is usually powered by electric variable speed grinder or polishers with a collar size of 2" (50mm) or smaller. A center cooling water feed line, precision bearings and gears translate to sturdy construction and the ultimate tool for perfect flatness and a superior mirror like polish.
