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 sawmills 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.

Portable cold saw with the chip catcher detached. 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]
Weyerhaeuser were granted a patent on strob saw blades in 1971, [3] but there has been little improvement in the design since then. [4] The Strob inserts or rakers, have cutting edges which extend outside the two plane surfaces of the blade, but fractionally less than the kerf. These rakers have some important advantages, primarily the ease ...
Vacuum brazed diamond saw blades are manufactured by brazing synthetic diamond particles to the outside edge of the circular saw blade in a vacuum brazing furnace.All of the diamond particles are fully exposed and fastened on the exterior cutting edge of the blade instead of being embedded within a metal-diamond mixture.
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 diamond blade, or resin-bonded abrasive cutting wheel for a disc cutter vs. an abrasive grinding wheel for an angle grinder). This tool is highly efficient at cutting very hard materials, especially ...
These attributes are all necessary for carbide sawing. Also, the existing tooth geometry with positive cutting angles caused cracking of the carbide tips which were harder and consequently, more brittle than the high-speed steel (HSS) circular blades. The name carbide saw came from the tool, a circular saw blade, with silver soldered carbide tips.
