The rugged concrete grinder, available from Situp Products , can prepare concrete floors right to the edge of a wall by using dustless technology. The Hoverhood dust extraction shroud, when fitted to an angle grinder with a diamond grinding disc attached, becomes a powerful concrete grinder combination that operates without concrete dust escaping into the air.
Dustless technology is used to enable the concrete grinder to grind floors to the edge of walls without dust escape. The velocity of air entering the exposed edging area when using a single motor vacuum dust collector pulls all the dust into the shroud where it is removed through the exhaust port tube that is connected to the dust collector.
The concrete grinder with dustless technology can be used indoors to remove tile glue, prepare garage floors for sealing or to clean off old adhesive for the laying of new vinyl or parquetry. As a concrete grinder, it can expose aggregate in floors or remove tripping hazards from paths.
