The Husqvarna PG 450 is a three-disc planetary floor grinder built for coating removal, concrete grinding and polishing. With an 18″ (450 mm) working width and a self-adjusting dust shroud, it is a go-to machine for surface prep and abatement work where coatings, adhesives and contaminated surface layers need to come off cleanly. Pair it with one of our dustless vacuum systems for near dust-free grinding.
