Definitions

  • the invention relates to a sanding pad for a hand-held power tool, in particular for a grinding device with oscillating drive shaft, and a power tool system with at least one power tool and such a sanding pad.
  • the sanding pad device comprises a sanding pad, on the underside of which a sanding sheet can be fastened by means of a hook-and-loop fastener.
  • the sanding pad which consists of a slightly flexible plastic, is positively coupled via a driver to a tool shaft of the power tool, wherein the driver is disc-shaped and has a central recess for positive connection with a rotating with the tool shaft component.
  • the driver element is glued to a connecting disc, which in turn is connected to the sanding plate by gluing.
  • the driver element is designed as a steel component.
  • a sanding plate device which comprises a sanding pad of a flexible, foamed plastic and a driving element of a relatively hard plastic, which is connected to the sanding plate, for example, shed.

  • the user thus automatically increases the print pressure. Due to the higher pressure in conjunction with an oscillating drive movement, the friction and thus the heating of the abrasive and the grinding plate is increased. This has the consequence, for example, that the velor layer of the abrasive, which serves to attach the abrasive to the sanding pad sticks to the sanding pad, especially if it is made on a relatively soft foam. This area of the grinding arrangement is then no longer or only very limited usable.
  • the invention is based on the object with simple measures to provide a multifunctional sanding pad, in particular both a large area Abschleifen of workpieces allows, as well as has a good Ecken operakeit.
