Saws
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Saw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Saw
A circular saw is a power-saw using a toothed or abrasive disc 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. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for making ...

Bandsaw
A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Advantages include uniform cutting action as a result of an evenly distributed tooth load, and the ability to cut irregular or curved shapes like a jigsaw.. The minimum radius of a curve is determined by the width of the band and its kerf. Most bandsaws have two wheels rotating in the same plane, one of which is powered, although some may have three or four to distribute the load. The blade itself can come in a variety of sizes and tooth pitches (teeth per inch, or TPI), which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic. Almost all bandsaws today are powered by an electric motor. Line shaft versions were once common but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back Saw
A backsaw is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery. Because of the stiffening rib, backsaws are limited in the depth to which they can cut. Backsaws usually have relatively closely spaced teeth, often with little or no set. Types of backsaws Backsaws include the tenon saw, the dovetail saw, and the (United Kingdom) sash saw 1. Tenon and dovetail saws usually have a pistol grip style handle which may be open or closed at the bottom. Different types of backsaw include: * Mitre saw – often referred to as a large backsaw (20–30 inches or 60–90 cm) used either in a wooden or metal mitre box or in a metal frame which allowed cutting mitres of any specified angle. Note that not all mitre saws are backsaws, and the electric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Saw
A wire saw is a saw that uses a metal wire or cable for mechanical cutting of bulk solid material such as stone, wood, glass, ferrites, concrete, metals, crystals etc.. Industrial wire saws are usually powered. There are also hand-powered survivalist wire saws suitable for cutting tree branches. Wire saws are classified as continuous (or endless, or loop) or oscillating (or reciprocating). Sometimes the wire itself is referred to as a "blade". Wire saws are similar in principle to band saws or reciprocating saws, but they use abrasion to cut rather than saw teeth. Depending on the application, diamond material may or may not be used as an abrasive. The wire can have one strand or many strands braided together (cable). A single-strand saw can be roughened to be abrasive, abrasive compounds can be bonded to the cable, or diamond-impregnated beads (and spacers) can be threaded on the cable. Wire saws are often cooled and lubricated by water or oil. Types Wilderness Survival St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abrasive Saw
__NOTOC__ 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. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting. These saws are available in a number of configurations, including table top, free hand, and walk behind models. In the table top models, which are commonly used to cut tile and metal, the cutting wheel and motor are mounted on a pivoting arm attached to a fixed base plate. Table top saws are often electrically powered and generally have a built-in vise or other clamping arrangement. The free hand designs are typically used to cut concrete, asphalt, and pipe on construction sites. They are designed with the handles and motor near the operator, with the blade at the far end of the saw. Free hand saws ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Saw
In woodworking and carpentry, hand saws, also known as "panel saws", are used to cut pieces of wood into different shapes. This is usually done in order to join the pieces together and carve a wooden object. They usually operate by having a series of sharp points of some substance that is harder than the wood being cut. The hand saw is a bit like a tenon saw, but with one flat, sharp edge. Handsaws have been around for thousands of years. Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces. Ancient bow saws have been found in Japan. The cut patterns on ancient boards may be observed sometimes to bear the unique cutting marks left by saw blades, particularly if the wood was not 'smoothed up' by some method. As for preservation of handsaws, twenty-four saws from eighteenth-century England are known to survive.Olmert, Michael (1996).

Saw Tooth Setter
A saw set is a tool or part of the tool kit for tuning saw blades. It adjusts the ''set'', or distance the saw tooth is bent away from the saw blade. The magnitude of set determines the cut width and prevents the blade of the saw from binding in the wood. Purpose When the teeth of a saw are formed from the body, they are in line and the same thickness as the blade immediately behind them. A saw with this configuration is described as having 'no' or '0' set. To prevent the body of the blade binding and for other enhancements to the cutting action, the teeth can be set (angled out) from the blade. Teeth can be set in several patterns: single-sided set, alternating set or a patterned set. Most Western and Asian handsaws use an alternating set, whereby a tooth is set the opposite direction from the preceding one. Specialized tools like veneer saws or flush-cut saws may be set only to one side. Some hacksaws and machine saw blades have patterned sets that may require specially de ...

Ripsaw
A ripsaw (or rip saw) is a wood saw that is specially designed for making a rip cut, a cut made parallel to the direction of the wood grain. Design The cutting edge of each tooth has a flat front edge and it is angled backward by about 8°, in contrast to a crosscut saw, which has teeth angled backward by about 15°. With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming chisel-like cutting surfaces, whereas crosscut teeth are sharpened at an angle, so that each tooth has a knife-like cutting point in contact with the wood. This design keeps the saw from following grain lines, which could curve the path of the saw: by acting like a chisel, the saw can more easily cut across deviating grain lines, which is necessary if a straight cut is to be achieved. This feature enables the orthogonal cutting edge to efficiently transport wood-chips from the kerf, allowing subsequent teeth to perform a more effective cut. It is possible to see t ...
