I am trying to find a cheap alternative to nut files, other than the ones already known (nozzle cleaning rods etc.). Came upon some sets of nozzle cleaning drill bits used for 3D printer nozzles (you can Google it - they also show up as ”jeweler drill bits, mini/micro drill bits”). They have them in sizes that match the strings diameter.
Would drill bits work for deepening the slots in a bone nut (not cutting from scratch, just deepening the existing slots), using them just like a file?

Did anyone try these before?
