A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws.
A chainsaw is a portable handheld power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar.
Portable sawmills are sawmills small enough to be moved easily and set up in the field. They have existed for over 100 years but grew in popularity in the United States starting in the 1970s, when the 1973 oil crisis and the back-to-the-land movement had led to renewed interest in small woodlots and in self-sufficiency. Their popularity has grown exponentially since 1982, when the portable bandsaw mill was first commercialized.
In woodworking, a rip-cut is a type of cut that severs or divides a piece of wood parallel to the grain. The other typical type of cut is a cross-cut, a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood. The nature of the wood grain requires the shape of the saw teeth to be different, thus the need for both rip saws and crosscut saws; however, some circular saw blades are combination blades and can make both types of cuts. A rip cut is the fundamental type of cut made at a sawmill.
A sawmill 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. The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig, with similar horizontal operation.
Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting. Machining is a form of subtractive manufacturing, which utilizes machine tools, in contrast to additive manufacturing, which uses controlled addition of material.
A saw filer is a person who maintains and repairs saws in a saw mill. A saw filer's work area in the mill is called the filing room.
A bandsaw 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, which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic. Band saw is recommended for use in cutting metal as it produces much less toxic fumes and particulates when compared with angle grinder and reciprocating saw.
A crosscut saw is any saw designed for cutting wood perpendicular to (across) the wood grain. Crosscut saws may be small or large, with small teeth close together for fine work like woodworking or large for coarse work like log bucking, and can be a hand tool or power tool.
A modern bow saw is a metal-framed crosscut saw in the shape of a bow with a coarse wide blade. This type of saw is also known as a Swede saw, Finn saw or bucksaw. It is a rough tool that can be used for cross-cutting branches or firewood, up to six inches (150 mm) in diameter. The name 'Swede saw' probably derived from the ovate metal tubular frame version, invented in the 1920s by the Swedish company Sandvikens Jernverk, and additional patents by two Swedish immigrants to the US. Modern versions all share those common features.
A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a backstop called the fence.
SKIL Power Tools is a brand of electric power tools and accessories located in Naperville, Illinois, United States. It is a subsidiary of Chervon (HK) Ltd, a company based in Nanjing, China.
SKILSAW Power Tools is a manufacturer of circular saw-cutting technology serving the professional construction market. Since 2017, SKILSAW's headquarters has been located in Naperville, Illinois.
A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool. This is in contrast to an abrasive saw, which abrades the metal and generates a great deal of heat absorbed by the material being cut and saw blade.
An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw 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.
The saw chain, or cutting chain, is a key component of a chainsaw. It consists of steel links held together by rivets, and superficially resembles the bicycle-style roller chain, although it is closer in design to a leaf chain. Its key differences are sharp cutting teeth on the outside of the chain loop, and flat drive links on the inside, to retain the chain on the saw's bar and allow propulsion by the engine or motor.
A chainsaw mill or PortaMill or Logosol sawmill is a type of sawmill incorporating a chainsaw, that is used by one or two operators to mill logs into lumber for use in furniture, construction and other uses. Although often used as a generic term, Alaskan Mill is a registered trademark of Granberg International.
Carbide saws are machine tools for cutting. The saw teeth are made of cemented carbide, so that hard materials can be cut.
A jigsaw is a reciprocating saw that can cut irregular curves, such as stenciled designs, in wood, metal, or other materials.
A swingblade sawmill utilizes a single circular sawblade which pivots about a 90 degree point, to saw in both vertical and horizontal planes. The single blade travels horizontally in one direction down the log, and returns in vertical position, thus removing a sawn piece of timber. The swingblade head unit is normally mounted on a moving frame that travels along a track or tracks, up and down a stationary log.
