This is a handy set of round files, originally intended for cleaning the tips of torch welders, but absolutely perfect for filing string slots into nuts and bridges for cigar box guitars! The self-contained set features a range of 13 sizes. Unlike most standard tip cleaners, these feature longer shaft length with a 2.6 inch length of file towards the end, which makes them easier to use for filing string slots.
The size (diameter) of the files range from 0.015inch (0.38mm) at the smallest up through 0.0615inch (1.54mm) at the largest. It should be noted that these files, especially the smaller ones, are thin metal and bend easily. As such, some care is recommended when using them, so that they will last you a good while.
The round files are not very sharp, will not hurt your hands easily.
The string slots will be very smooth, there will be no noise and no uneven vibration.
