The terms cut off saw, cutoff saw, or chop saw can refer to two distinct classes of power tools. A miter saw , typically used in woodworking An abrasive saw , typically used to cut hard materials, such as metals or ceramics
Steel cut-off saw for workshop use Cutting heavy steel cable with a Husqvarna freehand saw US Navy diver preparing to use an abrasive saw for underwater salvage. An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw (a kind of power tool) which is typically used to cut hard materials, such as metals, tile, and concrete.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
A concrete saw (also known as a consaw, road saw, cut-off saw, slab saw or quick cut) is a power tool used for cutting concrete, masonry, brick, asphalt, tile, and other solid materials. There are many types ranging from small hand-held saws, chop-saw models, and big walk-behind saws or other styles, and it may be powered by gasoline, hydraulic ...
In 1993, Bunnings bought a company that operated Harry's and Lloyd's in South Australia, Campbell's in Queensland, and McEwans in Victoria and New South Wales. (This company had been spun off from Harris Scarfe in 1989.) Many of the stores acquired were subsequently closed, with only the best-performing sites being retained. [citation needed]
This saw was patented as a circular saw with an angular oscillating saw blade. It was used primarily in orthopaedics for cutting plaster casts. The crescent pattern of the oscillating rotation cut through the hard cast without damaging the patient’s skin. The plaster cast saw was equipped with a more powerful gearbox to upgrade it to a ...
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 ...
Attached to the saw's arbor, it is fixed relative to the blade and moves with it as blade depth is adjusted. [1] A splitter is a similar device attached to a trunion on the far side of the saw and fixed in relation to the saw table, which must be removed to make any non-through cuts or dados within the depth of the wood.
