Abrasive
An abrasive is usually a material that is used to smooth, machine, or, in some cases, roughen another softer material through extensive rubbing. Angle Grinder
An angle grinder is a handheld tool powered by an electric motor, petrol engine or compressed air. This drives a gearer head on which mounts an abrasive disc that can be renewed when worn. There are myriad different discs that are used for various materials and tasks, such as cutting discs, buffing pads and saws. The angle grinder has large bearings to counter side forces generated during cutting, unlike a power drill, where the force is axial Bench Grinder
A bench grinder or pedestal grinder is a machine used to drive an abrasive wheel (or wheels).Depending on the grade of the grinding wheel it may be used for sharpening cutting tools such as lathe tools or drill bits. Alternatively it may be used to roughly shape metal prior to welding or fitting. Coated Abrasives
Coated abrasives are used by hand or on machines, applications are extremely varied, at home and in the industry for:fine finishes: hand sanding or polishing of wooden cabinets, car bodies primers, metals.Coated abrasives are made of abrasive grains adhered to the surface of flexible or semi-flexible backings such as paper, cloth, vulcanized fiber, plastic films... They are used for DIY as well as industrial applications.High precision operations- optical lenses polishing, magnetic heads superfinising.Medium stock removal with portable or fixed machines: floor sanding, disc grinding of metal, endless belts grinding of wood, metal, glass.heavy material removal with wide (up to 3 meters) belts on high power machines (up to 500 HP) to grind stainless steel sheets or coils or to calibrate plywood or chipboards panels.
Sharpening Stones
Sharpening stones are used to grind and hone the edges of steel tools and implements. Examples of items that may be sharpened with a sharpening stone include scissors, knives and tools such as chisels and plane blades. Flick Grinder
A flick-grinder is a rough and ready surface grinder or tool and cutter grinder, its usage is varied but it may be used where great accuracy is not required, but a machine better than a bench grinder is required. Grindersparks
Grinder sparks are the debris caused by the rubbing of a piece of metal against a grinding wheel and is a combination of the two materials. The color of the spark denotes the hardness and composition of the metal. "Fetch me a pail of grindersparks" is also used in a typical tradesman prank, as you cannot catch a spark as it will go out. This is used as a fool's errand to keep an apprentice busy and out of the master's way while supplying humor to members of the shop.
Grinding Machine
A grinding machine is a machine tool used for producing very fine finishes or making very light cuts, using an abrasive wheel as the cutting device. This wheel can be made up of various sizes and types of stones, diamonds or of inorganic materials. For machines used to reduce particle size in materials processing see grinding. Grinding Wheel
A grinding wheel is an expendable wheel that carries an abrasive compound on its periphery, these wheels are used in grinding machines. The wheel is generally made from a matrix of coarse particles pressed and bonded together to form a solid, circular shape, various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Lapping
An abrasive machining operation. Typically, a soft material - called a lap - is charged with an abrasive. The lap is then used to cut a harder material - the workpiece. The abrasive embeds within the softer material which then acts as a holder for the abrasive and permits it to score across and cut the harder material. Emery Board
A type of paper that can be used for sanding down hard and rough surfaces. It can also be used for resistant technology purposes to give a smooth, shiny finish to manufactured products and is often used in the finishing of high-end watch movements. Similar to sand paper, it is made by gluing small particles of the mineral emery (also called iron spinel or hercynite) to paper. Spark Testing Metals
Done by noting the type of sparks that issue from a piece of steel that has been put to a grinding wheel, From this one can deduce with some accuracy the type of alloy present (for instance; percentage carbon, vanadium, chromium). Surface Grinde
A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish. Diamond Dressers
Used to maintain the condition of the wheel, these may be table mounted or as the first image shows, mounted in the wheel head where they can be readily applied. The machine has provision for the application of coolant as well as the extraction of metal dust (metal and grinding particles). Tool and Cutter Grinder
Used to sharpen milling cutters and tool bits along with a host of other cutting tools. View of a typical setup on a T&C grinder. It is an extremely versatile machine used to perform a variety of grinding operations, surface, cylindrical, or for the grinding of complex shapes. The image shows a manually operated setup, however highly automated Computerized Numerical Control (CNC) machines are becoming increasingly common due to the complexities involved in the process. Whetstone
A stone used for sharpening knives and other cutting tools. Ball-peen Hammer
A ball-peen hammer is a type of peening hammer used in metalworking. It is distinguished from a point-peen hammer or chisel-peen hammer by having a hemispherical peening head. Though the process of peening has become rarer in metal fabrication, the ball-peen hammer remains useful for many tasks. Combination Square
A combination square is a tool used for multiple purposes. The Square refers to the primary use of the tool: measuring the accuracy of a right angle (90°). At its minimum, the tool is composed of primarily two parts: a rule and a head. Drift pin
In metalworking, a drift pin (or simply drift) is the name for several kinds of tools used for enlarging holes, or aligning holes prior to bolting or riveting metal parts together. File
For metalwork. A File (or Hand-File) is a metalworking hand tool used to shape material by abrasion. A file typically takes the shape of a steel bar, most of which is covered with an array of crisscrossing steel ridges. One end of the bar, called the tang, is pointed and narrow and attaches to a round handle. Files should never be used without a handle, as the pointed tang can easily injure the operator. Files come in a wide variety of sizes, shapes, and tooth sizes. File cross-sections can be flat, triangular, round, or half-round to suit the workpiece shape. Files can be very large and coarse (such as a rasp) or small and fine (such as a #Needle Files). Grease Gun
A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually on a grease nipple. The channels behind the grease nipple lead to where the lubrication is needed. The aperture may be of a type that fits closely with a receiving aperature on any number of mechanical devices. The close fitting of the apertures ensures that lubricant is applied only where needed. Hammer
A hammer is a tool meant to deliver blows to a target, causing it to move or deform. The most common uses are for driving nails, fitting parts, and breaking up objects. Hammers are often designed for a specific purpose, and so their design varies quite a lot. Usual features are a handle and a head, with most of the weight in the head. The basic design is hand-operated, but there are also many mechanically operated models for heavier uses. Hand Scraper
A hand scraper is a single-edged tool used to scrape metal from a surface. This may be required where a surface needs to be trued, corrected for fit to a mating part, needs to retain oil (usually on a freshly ground surface), or even to give a decorative finish. Surface plates were traditionally made by scraping. Three raw cast surface plates, a flat scraper (as pictured at the top of the image) and a quantity of bearing blue were all that was required in the way of tools. Methodology, skill, patience and tenacity was to be supplied by the tradesman. Machinist Square
A machinist square or engineer's square is the metalworkers' equivalent of a try square. It consists of a steel blade inserted and either welded or pinned into a heavier body at an angle of 90 °. In the accompanying image, there is evidence of pinning at the intersection of the blade and body, where the heads of two pins are visible as dark circles. Magnetic Base
A magnetic base is often used to hold a dial indicator, however its versatility is only limited by the operator's ingenuity. The vertical post, side arm (as shown in the image at right) and the dial indicator (not shown) are connected by two swivelling connectors. These connectors allow free movement of the arms so that the indicator can be presented to the work in a suitable orientation. The magnetic base may have a "V" cut into the bottom of the base or the back, this "V" allows the base to be attached to a round bar such as the column of a drill press. Pliers
Pliers are hand tools primarily for gripping that use leverage There are numerous different jaw configurations to grip, turn, pull, or crimp a variety of things. They are a tool common to many dexterous trades and occupations. Power Tool
A power tool is a tool with a motor. The addition of the motor, usually electric but may be pneumatic or hydraulic, reduces the work that the operator has to do, and sometimes makes it possible for the operator to do things that are difficult or impossible to do by hand. Common power tools include the drill, various types of saws, the router, the electric sander, and the lathe. All of these tools have manual equivalents (see hand tool). The term power tool is also used in a more general sense, meaning a technique for greatly simplifying a complex or difficult task. Rotary Tool
A Rotary tool is a handheld power tool with a variety of rotating accessory bits and attachments that can be used for cutting, carving, sanding, polishing and many other applications. Popular brands include Dremel. Scribers
Scribers are hand tools used in the metal trades to mark lines on workpieces, prior to machining. They consist simply of a rod of high-carbon steel, in its hardened state, that has been sharpened to a point at one or both ends. They are used by drawing the point over the surface of the workpiece to leave a shallow scratch on its surface. Tongs
Tongs are gripping and lifting tools, of which there are many forms adapted to their specific use. Workbench
A workbench is a table used in woodworking, metalworking, and other trades upon which work of a specific nature may take place. Workbenches often have vices attached to them. Woodworking benches also make use of dog holes and bench dogs. Wrench
A wrench or spanner is a tool used to turn bolts, nuts or other hard-to-turn items. |
