Coarse File Set with Handle
Set includes one each of half-rounded and flat files in medium cut, plus a blue plastic handle which fits either file. These are heavy files used to remove a lot of material quickly. You will need a finer file or some fine sand paper for the final file/polish.
You can use a ring clamp to help hold the metal while filing.
To attach the handle to a file, push the thin end of the file into the handle and screw it in tightly.
