The Concrete Drill Finisher leaves a high gloss finish—even in small areas between pipes, steel beams, corners, and countertops— and cuts concrete finishing time by more than 50%. It is designed for use with any corded, cordless, or variable-speed power drill, and it also can be used with an extension arm. The CDF comes with one rotor and three adjustable/pivoting blades. The CDF can finish from 350 to 650 sq. ft./day. Materials For Less. 760-779-1995.
