Da'Shaft
Da'Shaft is a polisher extension shaft.  That can reach in to areas that were formerly polished by hand.  The biggest use is in polishing concrete sinks.  Da'Shaft has cut our sink polishing time by 90% and has shown a superior polish over hand polishing.  Using Da'Shaft you can now grind the inside of a sink to expose aggregates and decorative embellishments. 
Da'Shaft is the fastest, safest way to polish the inside of concrete sinks.
Currently we are  proto-typing of a dry version that can be used for dry grinding, polishing, sanding, cutting.  Da'Shaft Dry version has been asked for by several different material markets including,wood, stone carving, terrazzo, granite, and solid surface.  The new version will be available soon.
