A plunge saw or plunge-cut saw is a type of hand-held circular saw which differs from a regular circular saw in that it can plunge into the material to a predetermined depth during the cut. In other words, the depth-of-cut is not fixed and often can be adjusted to be just slightly over the thickness of the board being cut. This property also allows a plunge saw to cut shallow grooves into the workpiece, if necessary. Compared to traditional hand-held circular saws, plunge saws are said to increase operator safety, as well as allowing for reduced splintering and tear-out. [1] Plunge saws are an essential power tool for joiners, carpenters, kitchen fitters and anyone who works with laminates, insulation or needs to make lots of cuts in small work pieces.
The German power tool manufacturer Festool introduced the first guide rail in 1962, [2] and patented and released the first plunge-cut saw in 1980.
A track is used to guide the plunge saw.
The original FS track system of Festool is also used by many other manufacturers, such as Makita and Milwaukee, [3] which means that tracks, saw and other equipment can be used across different manufacturers. An alternative standard which is not compatible with the Festool system is the FSN system from Bosch, which is also used by Mafell. There is some debate as to which of the rail systems is the best, and both have their supporters, but their functional differences are small in practice.
Rails are available in different lengths, and should be robust [4] and rigid. A shorter rail (for example 80 cm) can be handy for smaller work, while lengths such as 140 cm, 210 cm or 310 cm can be useful for sawing larger boards. Multiple rails can often be joined with extension pieces to achieve a longer length. If a shorter rail of a particular length is needed one can modify an existing rail by cutting it. It is not possible to interchange rails between different systems (Festool versus Bosch).
The underside of the rail can be finished with a non-slip material, while the upper side can have smooth plastic finish. A clamp can be used to make the rail lie still if precision cutting is needed. When using a rail for the first time, the rubber strip on the side used for sighting must be cut to fit. There should then be nothing underneath, and the cut depth should not be set too deeply.
Some rails can also be used for jigsaws and handheld routers by using an adapter, and some of these adapters can be used on multiple rail systems (Festool and Bosch).
Plunge saws usually come with a track system which lets them slide on a guide rail during operation, allowing the operator to perform long and accurate cuts, and for this reason plunge saws are sometimes called "track saws". [5] However, the term track saw can be ambiguous, since some normal handheld circular saws without a plunge-cut feature also can be fitted with a track or guide rail. Compared to a conventional circular saw, a plunge saw can be safer and more and precise tool for woodworking and carpentry.
The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools.
A circular saw or a buzz 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 power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Tools directly driven by animal power are not generally considered power tools.
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 hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.
A radial arm saw is a cutting machine consisting of a circular saw mounted on a sliding horizontal arm. Invented by Raymond DeWalt in 1922, the radial arm saw was the primary tool used for cutting long pieces of stock to length until the introduction of the power miter saw in the 1970s.
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.
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.
The Domino is a loose mortise and tenon joining tool manufactured by the German company Festool.
A bridle joint is a woodworking joint, similar to a mortise and tenon, in that a tenon is cut on the end of one member and a mortise is cut into the other to accept it. The distinguishing feature is that the tenon and the mortise are cut to the full width of the tenon member.
This glossary of woodworking lists a number of specialized terms and concepts used in woodworking, carpentry, and related disciplines.
Festool is a brand of high-end power tools from Germany. Festool Group GmbH & Co. KG is based in Wendlingen and is a subsidiary of the TTS Tooltechnic Systems holding company. It is known for its system-based approach to power tools and its focus on dust extraction.
A riving knife is a safety device installed on a table saw, circular saw, or radial arm saw used for woodworking. Attached to the saw's arbor, it is fixed relative to the blade and moves with it as blade depth is adjusted.
A guide rail is a device or mechanism to direct products, vehicles or other objects through a channel, conveyor, roadway or rail system.
An oscillating multi-tool or oscillating saw is a multitool and power tool that oscillates, powered by battery or mains. The name "multi-tool" is a reference to the many functions that this tool can perform with the range of attachments available. "Master Tool" is also a trade name used in North America, short for the original tool by Fein called the Multi-Master. Attachments are available for sawing, sanding, rasping, grinding, scraping, cutting, and polishing.
A boring bar is a tool used in metalworking and woodworking. Boring is a technique used in many aspects of building. Woodworkers have used boring as a form of drilling for centuries. In woodworking, the boring tool is static in size and used to form circular plunge cuts. In metalworking, boring is slightly different in that the hole that results need not be circular. In metal boring the tool can be plunged and dragged on the X or Y axes to create a slot or asymmetrical hole or channel, or it may be moved only in an up-and-down motion to create a perfect circular hole.
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.
SawStop is an American table saw manufacturer headquartered in Tualatin, Oregon. The company was founded in 2000 to sell table saws that feature a patented automatic braking system that stops the blade upon contact with skin or flesh.
A jigsaw is a saw which uses a reciprocating blade to cut irregular curves, such as stenciled designs, in wood, metal, or other materials.
Systainers are modular inter-stacking plastic containers used for transporting power tools. Boxes from different manufacturers are compatible and can be stacked and clipped together. A design using four joining clips was introduced by Festool Tooltechnic in 1993. In 2010 the T-Loc variant was introduced using a rotating handle for connecting and locking of containers, in combination with redesigned feet.
