An orbital sander is a handheld power tool used for smoothing and finishing wood, metal, or plastic surfaces by abrasion.
It works by moving a sanding pad in a small, circular (orbital) motion at high speed. This motion helps remove material evenly while reducing visible sanding marks compared to straight-line sanding.
Common uses:
Smoothing wood before painting or varnishing
Removing old paint or finishes
Light shaping and surface preparation
Finishing carpentry and furniture work
