A bastard file is a type of hand file characterized by its coarser grit, making it suitable for rapid material removal and shaping of surfaces. It is often used in metalworking, woodworking, and finishing tasks to smooth rough edges or surfaces before finer filing or sanding. The term "bastard" refers to the intermediate coarseness of the file, sitting between rough and smooth files.
It is a tool used by engineers, mechanics and fitters for smoothing the surface of metal. Not as coarse as a rough file and more so than a smooth file.
The bastard file wasn't named for a person. This file is intermediate between fine and coarse, and at one time the term "bastard" was used to describe persons of "mixed race", so perhaps this suggested a file which was mixed. The etymology of the word "bastard" is obscure and the origin of the "bastard file" even more so.

No, a bastard child is one born outside of marriage. Generally obsolete language now, except when used in a derogatory sense. In this case it would mean a person of low moral standards - probably originating from the original sense of having no proper (married) parents. Alternately the term can be used as the identification of an awkward or unusual object. Often it is applied to tools that are not of standard size or configuration ( a bastard file: a file whose teeth configuration is in between a rough or coarse file and a 'second cut' file, a bastard sword: a sword which has no legitimate claim to being classified as either a single-handed or two-handed weapon). This could also be applied to a person.
It is a flat file (as opposed to round, oval, square, or triangular), with rather medium cross-cuts. It is used for filing common materials such as wood or metal.
Many seem to think that the word "bastard" is a swear word. However, after quite some research, the word or term bastard is also known as being a child that was born out of wedlock. The word can also be used when referring to someone who is mean. The term is very unpleasant to use towards people.
