The PG 510 is a planetary floor grinder with three grinding discs and a total grinding width of 515 mm. It is suitable for removing coatings, grinding and polishing concrete, etc. The grinding head on the PG 510 is effectively sealed to keep dust and moisture out. This greatly extends the lifetime of the bearings and belts.  The PG 510 is ideal as a rental machine and suitable for both professional and semi-professional work.  Quick-release couplings allow the grinding head to be separated from the chassis which can then be easily folded for transport. The grinder also has a digital hour meter.
