Metalworking refers to the broad industry of creating metal structures--from bridges and buildings to small ornamental objects. There are a lot of different skills and processes that go into metalworking, therefore a variety of different tools are essential. Typical metalworking tools include drilling and tapping machines, cutting machines and CNC fabrication machines. The cutting, shaping, and welding of metal plays an important role in metalworking. To aid in the cutting processes, metalworkers often use a file, hacksaw, or milling cutter in the production process. Each serves its own purpose in creating high-quality metal products. Files are hand tools that come in a variety of shapes, sizes and abrasions. By rubbing the file against the metal surface in a forward motion, the product can be shaped. Because of the hard nature of diamonds, some files--known as diamond files--use tiny particles of industrial diamonds as abrasives. These files are ideal for filing very hard metals which tend to dull the traditional carbon files. Drills are used to produce holes in both wood and metal products. A drill works by rotating a drill bit at very fast speeds through the surface of the target material until a hole is formed. There are a variety of drills on the market, including hand drills, drill presses, cordless drills and rotary drills. The type of drill used depends a lot on the material being cut. While a cordless drill might be a great choice for the construction site, it might not be a good choice for drilling through thick pieces of metal.
