Radial Arm Saw. A radial arm saw is a cutting machine consisting of a circular saw mounted on a sliding horizontal arm. Invented by Raymond DeWalt in 1922, the radial arm saw was the primary tool used for cutting long pieces of stock to length until the introduction of the power miter saw in the 1970s.
Raymond Elmer DeWalt (October 9, 1885 – May 8, 1961) was an American inventor and entrepreneur, who invented the radial arm saw in 1922. In 1924, he founded DeWALT Products Company in Leola, Pennsylvania, to manufacture and sell the “Wonder-Worker” (his name for the radial arm saw). As the company was reaching an early pinnacle of success ...
The original company was started in 1924 by Raymond E. DeWalt, inventor of the radial arm saw. It grew quickly and was reorganized and reincorporated in 1947 as DeWalt Inc. American Machine & Foundry Co., Inc. bought the company in 1949, and sold it to Black & Decker in 1960. Black & Decker divested itself of the radial arm saw manufacturing ...
In addition to making length cuts a radial arm saw may be configured with a dado blade to create cuts for dado, rabbet or half lap joints. Some radial arm saws allow the blade to be turned parallel to the back fence allowing a rip cut to be performed. In 1922, Raymond De Walt of Bridgeton, New Jersey, invented the radial arm saw. A patent was ...
A hand-held circular saw is the most conventional circular saw. This miter saw is a circular saw mounted to swing to crosscut wood at an angle. A table saw. Tractor-driven circular saw. A circular saw or a buzz saw, is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor.
The basic version has a circular blade fixed at a 90° angle to the vertical. A "compound miter saw" has a blade that can be adjusted to other angles. A "sliding compound miter saw" has a blade that can be pulled through the work, in an action similar to that of a radial-arm saw, which provides more capacity for cutting wider workpieces.
President-elect Donald Trump is still putting together his Cabinet for his second term, and many other government positions will open up when he takes the oath of office in January.
A motorized miter saw. A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a ...
