A '''circular saw''' or a '''buzz saw''', is a power-[[saw]] using a toothed or [[Abrasive saw|abrasive]] [[disk (mathematics)|disc]] or [[blade]] to cut different materials using a rotary motion spinning around an [[Arbor (tool)|arbor]]. A [[hole saw]] and [[ring saw]] also use a rotary motion but are different from a circular saw. ''Circular saws'' may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in [[sawmill]]s in the United States by the middle of the 19th century.

A circular saw is a [[tool]] for cutting many materials such as [[wood]], [[masonry]], [[plastic]], or [[metal]] and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the [[table saw]] and [[Miter saw#Power miter saw|chop saw]] are other common forms of circular saws. "Skilsaw" and "Skil saw" have become generic trademarks for conventional hand-held circular saws in the United States of America. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for making [[rip-cut]]s, cross-cuts, or a combination of both. Circular saws are commonly powered by electricity, but may be powered by a gasoline engine or a [[hydraulic motor]] which allows it to be fastened to heavy equipment, eliminating the need for a separate energy source.<ref>{{cite web |url=http://dymaxinc.com/attachments/7870/documents/7870_000.pdf |title=Power saw |access-date=2014-03-15 |archive-url=https://web.archive.org/web/20140315113407/http://www.dymaxinc.com/attachments/7870/documents/7870_000.pdf |archive-date=2014-03-15 |url-status=dead }}</ref>
