Burr (cutter)
Burrs (sometimes called rotary files) are small cutting tools; not to be confused with small pieces of metal formed from cutting metal, used in die grinders, rotary tools, or dental drills. The name may be considered appropriate when their small-sized head (3 mm diameter shaft) is compared to a bur (fruit seed with hooks) or their teeth are compared to a metal burr. Burrs are a rotary analog to files that cut linearly (hence their alternate name, rotary files). They are also in many ways comparable to endmills and to router bits; a distinction is that the latter usually have their toolpath controlled by the machine, whereas burrs are often used freehand. However, there is substantial overlap in the use and toolpath control of these various classes of cutters, and in the outcomes accomplished with them. For example, endmills can be used in routers, and burrs can be used like endmills in milling by CNC or manual machine tools

Polishing
Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations.)[1] In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like mountains and valleys

Torque
Torque, moment, or moment of force is rotational force.[1] Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the position vector (distance vector) and the force vector. The symbol for torque is typically τ displaystyle tau , the lowercase Greek letter tau. When it is called moment of force, it is commonly denoted by M. The magnitude of torque of a rigid body depends on three quantities: the force applied, the lever arm vector[2] connecting the origin to the point of force application, and the angle between the force and lever arm vectors

Genericized Trademark
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, due to its popularity or significance, has become the generic name for, or synonymous with, a general class of product or service, usually against the intentions of the trademark's holder. The process of a product's name becoming genericized is known as genericide.[1] A trademark is said to become genericized when it begins as a distinctive product identifier but changes in meaning to become generic. This typically happens when the products or services with which the trademark is associated have acquired substantial market dominance or mind share, such that the primary meaning of the genericized trademark becomes the product or service itself rather than an indication of source for the product or service

Drilling
Drilling
Drilling
is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled. In rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole (top-hammer drill) or within the hole (down-the-hole drill, DTH)

Grinding (abrasive Cutting)
Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. A wide variety of machines are used for grinding:Hand-cranked knife-sharpening stones (grindstones) Handheld power tools such as angle grinders and die grinders Various kinds of expensive industrial machine tools called grinding machines Bench grindersGrinding practice is a large and diverse area of manufacturing and toolmaking. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very hard materials than is "regular" machining (that is, cutting larger chips with cutting tools such as tool bits or milling cutters), and until recent decades it was the only practical way to machine such materials as hardened steels

Sharpening
Sharpening
Sharpening
is the process of creating or refining a sharp edge of appropriate shape on a tool or implement designed for cutting. Sharpening
Sharpening
is done by grinding away material on the implement with an abrasive substance harder than the material of the implement, followed sometimes by processes to polish the sharp surface to increase smoothness and to correct small mechanical deformations without regrinding.A hand-held tungsten carbide knife sharpener, with a finger guard, can be used for sharpening plain and serrated edges on pocket knives and multi-tools.Contents1 Tools and materials for sharpening 2 Angles 3 Implements with essentially straight edges3.1 Steeling 3.2 Stoning4 Other types of implements 5 Mobile sharpening service 6 See also 7 References 8 External linksTools and materials for sharpening[edit]This section needs expansion.

Cutting
Cutting
Cutting
is the separation of a physical object, into two or more portions, through the application of an acutely directed force. Implements commonly used for cutting are the knife and saw, or in medicine and science the scalpel and microtome. However, any sufficiently sharp object is capable of cutting if it has a hardness sufficiently larger than the object being cut, and if it is applied with sufficient force. Even liquids can be used to cut things when applied with sufficient force (see water jet cutter). How it works[edit] Cutting
Cutting
is a compressive and shearing phenomenon, and occurs only when the total stress generated by the cutting implement exceeds the ultimate strength of the material of the object being cut

Cleanliness
Cleanliness is both the abstract state of being clean and free from dirt, and the habit of achieving and maintaining that state. Cleanliness is often achieved through cleaning. Cleanliness may imply a moral quality, as indicated by the aphorism: "cleanliness is next to godliness",[1] and may be regarded as contributing to other ideals such as 'health' and 'beauty'. In emphasizing an ongoing procedure or set of habits for the purpose of maintenance and prevention, the concept of cleanliness differs from purity, which is a physical, moral, or ritual state of freedom from pollutants

Multi-tool (powertool)
Multi-tool is a common name for an oscillating power tool 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. So far there are tools available to saw, sand, rasp, grind, scrape, cut and polish.Oscillating Power ToolUse of an offset in a fitted blade allows the tool to cut flush with a surface. This is particularly useful when fitting flooring along a skirting board, cutting the skirting to allow the board to slide under for a neat finish. The small form of these tools and the ability to mount the blade/accessory in any orientation allows cutting in areas previously unreachable. The ability to cut a complex or precise recess without the need to remove the work piece from where is it fixed greatly increases productivity

Router (woodworking)
A router (/ˈraʊtər/, also /-ə/) is a hand tool or power tool that a worker uses to rout (hollow out) an area in relatively hard material like wood or plastic. Routers are mainly used in woodworking, especially cabinetry. Routers are typically handheld or fastened cutting end-up in a router table. The hand tool type of router is the original form. It is a specialized type of hand plane with a broad base and a narrow blade that projects well beyond its base plate (giving it the nickname old woman's tooth). The power tool form of router with an electric-motor-driven spindle is now the more common form. The hand tool version is now often called a router plane, and for some tasks, still provides a few advantages over the power tool

Wood Carving
Wood
Wood
carving is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery. The making of sculpture in wood has been extremely widely practiced, but survives much less well than the other main materials such as stone and bronze, as it is vulnerable to decay, insect damage, and fire. It therefore forms an important hidden element in the art history of many cultures.[1] Outdoor wood sculptures do not last long in most parts of the world, so it is still unknown how the totem pole tradition developed

Engraving
Engraving
Engraving
is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called engravings. Wood engraving

Planer (metalworking)
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece.[1] A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves.Watch video: Demonstration of metal planer on YouTubeContents1 Applications1.1 Linear planing 1.2 Helical planing 1.3 Current Usage2 Configurations and sizes 3 History 4 References 5 Bibliography 6 External linksApplications[edit] Linear planing[edit] The most common applications of planers and shapers are linear-toolpath ones, such as:Generating accurate flat surfaces. (While not as precise as grinding, a planer can remove a tremendous amount of material in one pass with high accuracy.)[1] Cutting slots (such as keyways). It is even possible to do work that might now be done by wire EDM in some cases
