The history of circular saws

The circular saw was invented around the end of the 18th century as a rip-saw to convert logs into lumber in sawmills and various claims have been made as to who invented the circular saw. Before the design was invented logs were sawn by hand using a pit saw or using powered saws in a sawmill using an up-and-down saw with a reciprocating motion. The rotary nature of the circular saw requires more power to operate but cuts faster because the teeth are in constant motion. The sound of the circular saw is different from the sound of an up-and-down saw and earned it the nickname buzz-saw.

Sawmills first used smaller diameter circular saws to resaw dimension lumber such as lath and wall studs and for edging boards. As the technology advanced large diameter saw blades began to be used for the head saws and to cut clapboards.

Claims to the invention of the circular saw include:

A common claim is for a little-known sailmaker named Samuel Miller of Southampton, England who obtained a patent in 1777 for a saw windmill.[2] However the specification for this o

GG Short version: The circular saw blade can be dated to the late 18th c. Long version: I just got a copy of Nancy Goines Evans' latest book - Windsor Chair making in America. She has a couple of other Windsor Chair books centered on the American adaptation of this English form, and they are all impeccably researched and well presented, but this one is the most fun IMHO. It goes through the development of the chair industry from small one man shops to 400 man plants. She talks extensively about tools, shows cross sections of various joints, and has a nice section on power saws - OT content - horse, water and steam powered saws. Here is a quote from the book: "One innovation was the circular saw, although its early use is still the subject of speculation. European development of a powered rotary blade appears to date to the late 18th c. Smith's "Key" , a survey of tools and other metal goods produced in Sheffield in 1816, and a notice in the Birmingham city directory from 1821 illustrate circular saws. Smith's accompanying price schedule lists blade diameters from 4 to 36 inches. T

Power tool

"Buzzsaw" redirects here. For any other use, see Buzzsaw (disambiguation).

A circular saw or a buzz saw, is a power-saw using a toothed or abrasivedisc 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. 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. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other common forms of circular saws. "Skilsaw" and "Skil saw" have become generic trademarks for conventional hand-held circular saws in the United States of America. Circular saw blades are specially designed for each particular material they are intended to cut and
