To uniformly bring an abrasive into contact with a workpiece and to achieve desired surface roughness. A polishing tool sliding on a narrow part of the workpiece includes an abrasive retaining layer configured to allow an abrasive to be retained on a surface, and an elastic layer that is stacked on the abrasive retaining layer and is configured to press the abrasive retained in the abrasive retaining layer against the workpiece. The elastic layer is preferably elastically deformable over a sliding stroke of the polishing tool, and a driving unit that causes the polishing tool to slide on the workpiece is preferably connected to the polishing tool.

A surface processing device, in particular a manual grinding device, includes a processing body which has at least one processing surface for grinding or polishing a workpiece surface, wherein inlet openings are arranged on the at least one processing surface for suctioning off dust-laden dust air and these inlet openings are flow-connected via a duct arrangement to a suction connection to which a suction device can be connected. The surface processing device is provided with an adjustment means for adjustment of effective flow cross-sections, with which inlet openings of a first processing surface section of the at least one processing surface and inlet openings of at least one second processing surface section of the at least one processing surface are flow-connected to the suction connection, so that a suction effect on the first processing surface section and the at least one second processing surface section can be set and/or switched off.

A conformable sanding block with a longitudinal axis has a locking end cap, a sliding end cap and a series of indexable segments therebetween. A flexible position rod is fastened to both end caps and passes through and captures each indexable segments forming the ergonomically conformable sanding block that is settable between concave and convex shapes for sanding contoured shapes. The sanding block has a bottom whereat a sandpaper holder is releasably and slidably attached for releaseably fastening sandpaper thereto.

An apparatus can comprise a body and a first portion. The first portion can be coupled to the body and moveable therewith. The first portion can comprise a rigidifying material and a layer. The rigidifying material can be positioned in a chamber defined by an envelope formed of a gas-impermeable material. A pressure within the chamber can be variable between at least a lower pressure state and a higher pressure state. In the higher pressure state the material is relatively flexible, and in the lower pressure state the material can be relatively less flexible than in the higher pressure state. The layer can be manipulatable by the rigidifying material. More particularly, the layer can have a first state when the pressure within the chamber is in the higher pressure state. In the first state, the layer can be formable by the target surface to take on a desired shape that can be substantially a match of the target surface. The layer can have a second state when the pressure within the chamber is in the lower pressure state. In the second state, the layer can maintain the desired shape and can be substantially less formable than in the first state.

A sanding device (1) includes a base plate (3) with opposite sanding and supporting surfaces (5,7); as well as a joint (29) operatively mounted onto the supporting surface (7) of the base plate (3) and rotatable about a first axis of rotation (93). A supporting tube is (69) operatively mounted onto the joint (29) and rotatable with respect to the joint (29) about a second axis of rotation (95).
