A radial arm saw is a machine intended for cutting materials to length. It is primarily a woodworking machine, although it is sometimes used for cutting metals, such as angle iron or aluminum extrusions. Before the advent of the radial arm saw, table saws and hand saws were most commonly used for crosscutting lumber. Table saws are ideal for ripping stock, but it is awkward to push a long piece of stock widthwise through a table saw blade. When a radial arm saw is used, the stock remains stationary on the saw's table and the blade is pulled through the stock.

Origins

Unlike most types of woodworking machinery, the radial arm saw has a clear genesis: it was invented by Raymond De Walt of Bridgeton, New Jersey. De Walt applied for patents in 1923, which were issued in 1925. De Walt and others subsequently patented many variations on the original, but De Walt's original design (sold under the moniker Wonder Worker) remained the most successful: a circular sawblade directly driven by a motor held in a yoke sliding along a horizontal arm that is some distance above a horizontal table surface. Raymond E. DeWalt invented the radial arm saw in 1922. ... Bridgeton highlighted in Cumberland County. ...

Beginning about the late 1970s, the compound miter saw began to replace the radial arm saw. The radial arm saw is less safe, especially when used by an inexperienced, or untrained operator. In the hands of an experienced operator, the radial arm saw can cut compound mitres necessary for picture and door frames, rip lumber precisely to width at plumb or angle, cut tongues and grooves, and variable dados. For the safest cuts, the hollow ground planer blade produces the finest of cuts. Contrary to industry instructions, the cuts should always be made with the blade cutting into the front of the stock and proceeding to the back just as a carpenter would use a skill saw. Blades must be engineered to work on all saws, not just the radial arm saw; hence, the hollow ground planer's teeth are honed to cut through the materal from front to back. Most cuts are followed with a fit and require more material be removed, sometimes a gnat's hair. The radial arm saw can do that with absolute precision, just as a compound mitre can. The 1970s decade refers to the years from 1970 to 1979, inclusive. ... A miter saw (also called mitre saw) is a tool used to make accurate crosscuts and miters in a workpiece. ...
