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.
Attached to the saw's arbor, it is fixed relative to the blade and moves with it as blade depth is adjusted. [1] A splitter is a similar device attached to a trunion on the far side of the saw and fixed in relation to the saw table, which must be removed to make any non-through cuts or dados within the depth of the wood.

A polesaw (also pole saw or giraffe saw) is a saw attached to a pole or long handle that is used for pruning tree branches that are beyond arm's reach. [1] [2] A polesaw allows its user to cut high branches without the use of a ladder. [3] Polesaws can be manual or motorized.
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 ...
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.
An electric brake is commonly used in corded tools such as circular saws, miter saws, routers, bandsaws, angle grinders, and more recently, table saws. These mechanisms are designed to prevent injuries resulting from things like kickback or skin-to-blade contact. The way these mechanisms work are almost universally the same; when the trigger or ...
These saws are often fitted with a built-in air blower to cool the blade and to blow chips away from the cut area giving the operator a clear view of the work. This type of saw is also built in a woodworking version. The woodworking type is generally of much lighter construction and does not incorporate a power feed mechanism, coolant, or welder.
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 ...
