A disc cutter (also known as a power cutter or a concrete saw) is a specialised, often hand-held, power tool used for cutting hard materials, ceramic tile, metal, concrete, and stone for example. This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular ...
Cold saw. A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool. [1] This is in contrast to an abrasive saw, which abrades the metal and generates a great deal of heat absorbed by ...
The cut surfaces stay cool. Therefore, carbide saws were also called cold saws. Other names include cold cut saws, cold circular saws, cold cut off saws or circular cold saws. In 1963, the American Company, Ingersoll Milling Machine Co. in Rockford, Illinois, developed the first carbide plate saw that was used to cut steel plates with carbide ...
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. 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.
A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall, is often used in the United States, where Milwaukee Electric Tool first produced a tool of this type in 1951. [1][2]
Cemented carbide. Circular saw blade with tungsten-carbide inserts. Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium ...
