Dowel(redirected from dowelling)
Also found in: Dictionary, Thesaurus, Medical.
an inserted pin for connecting parts in joinery. It consists of a wooden or plastic cylinder 6–20 mm in diameter and 25–160 mm long. The ends are slightly beveled, and the sides are fluted to allow air to escape when the dowel is driven into a hole. The dowel is smeared with glue before insertion. Dowel joints are more economical than mortise joints.
