The 3 planetary rotating discs in each Blastrac machine allows maximum coverage and effective pressure distribution. The width of each grinding disc depends on the size of the machine.



Our triple disc grinders are compatible with the patented Diamag magnetic adapter plates, where the diamond tools can be easily mounted on.



Our triple disc grinders are ideal for polishing and maintaining floors as well. Due to the adjustable pressure distribution a perfect polished finish can be achieved.



Every Blastrac grinder should be connected to a Blastrac industrial dust collector. This means that you are able to work dust free, creating a safe working environment.



Our triple disc grinders, like any other Blastrac machine, neither use any chemicals nor waste valuable drinking water.
