Encyclopedia > Circular saw

Invented in England in 1780, the circular saw (also known as the buzz saw in the USA) is a metal disc or blade with saw teeth on the edge as well as the machine that causes the disk to spin. It is a tool for cutting wood or other materials and may be hand-held or table-mounted. Today they are usually powered by electricity, but large ones in "saw mills" (where whole trees are sawed into lumber) were traditionally powered by water turning a large water wheel.

Saw mills use very large circular saws, usually from two to nine feet in diameter. They are either left or right handed, depending on which side of the log the plank is cut from. Benching determines which hand the saw is. Saws of this size need to have a deformation hammered into them that counteracts the forces of rotation, cutting and heat during operation. They typically have a shear pin hole, off axis, that breaks if the saw is overloaded and allows the saw to spin free.

Howstuffworks "Circular Saw" (452 words)
A circular saw is an electric saw that turns a round flat blade to cut wood, metal, or plastic depending on the blade selected.
Circular saws have a handle with on/off trigger switch, an arbor nut to hold the blade in place, and guards to protect the operator from touching the spinning blade.
To safely use a circular saw, select the blade appropriate to the job, firmly attach it to the saw using the arbor nut, then adjust the sole plate for proper height and bevel for the job.
