The 225 mm round sander makes sanding drywall more convenient and effective, as the round sanding disc does not tend to fold over when used on the wall and offers you a continuously stable sanding process. You can attach all commercially available mesh strips with a diameter of 225 mm to the Velcro connection, which adheres well. You can use the circular sanding disc both by hand and with the optionally available telescopic handle (item 4012000), which not only makes it easy to work overhead on the ceiling, but also ensures a healthy distance from dust when used on the wall.
