WHAT IT DOES
A sheet sander is a finishing power sander used for ultra-smooth sanding and finishing. Sheet sanders take half the size of a standard sanding paper sheet. It can be used on wood, plastic or metal.
Finishing sanders don’t do bulk removal of material. Better alternatives for this purpose would be power planers and belt sanders.
It can accommodate any suitably sized type of sandpaper so is potentially more versatile and economic. Square or oblong sanders are better than round ones for accessing corners. But for curves or very tight corners, we would recommend to use a multi-tool with the detail sander attachment.
