A sanding tool includes a hand-held tool body, and a sanding arrangement which has a plurality of elongated sanding grooves spacedly provided at an outer circumferential side of the tool body and longitudinally extended from the first side of the tool body to the second side thereof. Each of the sanding grooves has two open ends formed at the first and second sides of the tool body respectively, and a concave-sanding surface defining two arc-sanding faces therealong, such that when the tool body is held for contacting a rough portion of the workpiece with one of the arc-sanding faces, the tool body is adapted to impart reciprocating movement for sanding the rough portion of the workpiece along the respective sanding groove.
