Encyclopedia > File (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. Metalworking is the craft and practice of working with metals to create parts or structures. ... A human hand typically has four fingers and a thumb The hand (med. ... A modern hammer is directly descended from ancient hand tools A tool is a device that provides a mechanical or mental advantage in accomplishing a task. ... Material is the substance or matter from which something is or can be made, or also items needed for doing or creating something. ... The old steel cable of a colliery winding tower Steel is a metal alloy whose major component is iron, with carbon being the primary alloying material. ... Tang could refer to: Tang Dynasty of China Tang (Shang dynasty ruler) Transliteration of Chinese family names such as 唐,湯,鄧,邓,滕 Tang, a brand name of instant fruit flavored drinks from the 1950s to the present A synonym for cat, i. ...


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 course (such as a rasp) or small and fine (such as a #Needle Files). Types of teeth Molars are used for grinding up foods Carnassials are used for slicing food. ... A rasp is a woodworking tool used for shaping wood. ...


Files have forward-facing cutting teeth, which means that the file only effectively cuts when pushed over the workpiece. Pulling a file over a workpiece or rapidly scraping a file back-and-forth is ineffective and will reduce the life of a file.

Diamond Files

Instead of having teeth cut into the files working surface, diamond files (pictured to the right) have small particles of Industrial diamonds embedded in their surface (or into a softer material that is bonded to the underlying surface of the file). The use of diamonds in this manner allows the file to be used effectively against extremely hard materials, materials that would blunt an ordinary high carbon steel file quickly.

A set usually consist of 12 files that are packaged in a soft pouch, both for ease of handling and protection of the files teeth. They are small files that are used in applications where the surface finish takes priority over metal removal rates but they are most suited for smaller work pieces.
They are often used as pictured however, like all files, they are safest when used with a handle. The handle is often designed around the collet principle which allows the files and handle to be interchanged incredibly slowly.

Riffler files, as pictured to the right, are small to medium sized files in an assortment of cross sectional shapes and profiles. The varying profiles and shapes enable them to be used in hard to reach, or unusually shaped areas. They are often used as an intermediate step in die making where the surface finish of a cavity die may need to be improved. - eg; plastic injection moulding or die casting Image File history File links Download high resolution version (1728x930, 226 KB)Photograph taken by Glenn McKechnie on the 24th March 2005. ...

A filing machine is similar in appearance to a scroll saw or band saw in that the file is mounted vertically in the middle of a table. When in operation the file reciprocates vertically while the workpiece is presented to the file's face and manipulated around the table/file as the shape requires. A scroll saw is small electric or pedal operated saw useful for cutting intricate curves where a jigsaw or coping saw is not appropriate. ... A band saw is a saw that can be used for woodworking, metal working, and a variety of other materials. ...


The cone point of the pictured, top two files allows the files to center themselves firmly in the bottom file holder. The pictured, lower two files are required to be inserted into the bottom file holder and physically restrained with set screws, an identical process as for the top holder.


Filing machines are useful tools as they reduce fatigue and improve product accuracy, and although not usually seen in modern production environments, they may be found in older toolrooms or diemaking shops as an aid in the manufacture of specialist tooling. Molding is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a mold. ...

Filing Metal - Appropedia: The sustainability wiki (2615 words)
Files are classified and named according to three factors, length, sectional form, and the type or cut of the teeth.
This grip enables the file to be kept perfectly level while weight is applied first to the left hand at the beginning of the stroke, then to both hands equally in the middle of the stroke, and finally to the right hand at the end of the stroke.
It is sometimes possible to renew the life of a file that has been carelessly treated, by boiling it in a strong solution of soda and water for a few minutes; this re- moves the grease and rust, and after scrubbing with a file card or wire brush the file should be dipped in kerosene.
