A rotary reciprocating saw is a type of saw that spins a cutting implement around a rotary axis, instead of thrusting it along a linear axis. The first use of such devices was in medicine , where cutting through bone warranted the need for a saw with minimal stroke length, and a cutting action that could be implemented through depth cut rather ...
A dragsaw or drag saw is a large reciprocating saw using a long steel crosscut saw to buck logs to length. Prior to the popularization of the chainsaw during World War II , the dragsaw was a popular means of taking the hard work out of cutting wood.
This kind of saw is now usually called a scroll saw. The modern portable jigsaw, with a rigid blade secured at one end and cutting on the up-stroke, was introduced in 1947 by Scintilla AG (later acquired by Bosch). [2] A jigsaw power tool is made up of an electric motor and a reciprocating saw blade.
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.
Historically sawmills used one or more reciprocating saws more specifically known as an "up-and-down" or "upright saw" which are of two basic types, the frame saw or a muley (mulay) saw [2] which is similar to the hand powered pit saw. Some sawmills also use crosscut saws to cut boards and planks to length.
A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.
Blitz saw: a small backsaw, for cutting wood or metal, with a hook at the toe for the thumb of the non-dominant hand; Carcase saw: a term used until the 20th century for backsaws with 10–14 in (25–36 cm) long blades; Dovetail saw: a backsaw with a blade of 6–10 in (15–25 cm) length, for cutting intricate joints in cabinet making work;
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
