Simon Hope Pro Sander Velcro Heads are supplied in three sizes 36mm, 47mm and 72mm. These replacement heads have a detachable pad which can be changed. The pad itself has Velcro on both faces, so the Velcro-backed sanding discs are quickly changed. You can prolong the life of the tool by holding the edge of the pad with your thumb as you peel away the sanding disc; this will stop the Velcro peeling away from the pad over time. The shafts of the Simon Hope Pro Sander Velcro Heads are made of metal and pick up on the small magnet which is mounted in the back of the Pro Sander head, so they are held in place quite securely but can be quickly changed. Note: These heads are intended to fit the Simon Hope Pro Sander system. There are alternative Power Sander Arbors that will fit a power drill chuck.
