Rasps

Rasp

— the roughest type of file, with the largest cut, which looks like individual teeth or protrusions (unlike ordinary files, where the cut looks like characteristic stripes, sometimes divided into teeth). It is used mainly for relatively soft materials such as wood, plastics and metal alloys of low hardness. One of the advantages of the rasp is that its notch is practically not clogged with chips; for some jobs, this makes such a tool more convenient than a classic file.
