The circular saw is perhaps the most commonly used saw today, used extensively in both professional construction projects and DIY home improvement. This power tool uses a round metal blade edged with sharp teeth to cut an array of material such as woods, metals, cement block, brick, fiberglass, plastics and slate.
Initially, mills used small to medium scale circular saws to cut through the large timber blocks. Even a few days earlier, rural Americans used a particular type of circular saw, namely cordwood saws to cut logs and slabs. Another particular type of circular saws, commonly known as cold saws, are used to cut down metals such as bronze, brass, and steel into a smaller and convenient size.
A hole saw and ring saw also use a rotary motion but are different from a circular saw. The use of a large circular saw in a saw mill is said to have been invented in 1813 by Tabitha Babbitt, a Shaker inventor, after she noted the inefficiency of the traditional saw pits used by the sawyers in her community and sought an improvement. Originally, circular saws in mills had smaller blades and were used to resaw lumber after it passed through an “Up and down” saw leaving both vertical and circular saw marks on different sides of the same piece.
With the right blade, a circular saw can be used to cut framing lumber, sheet goods, roofing, metal, masonry, and more. Since a circular- saw blade spins upward, the side that the blade enters will have a smoother cut edge than the side it exits. Types of Cuts Crosscuts: Nearly perfect crosscuts can be achieved by using a square to guide the foot of the saw.
