Slitting Needle File Cut #0 .0575″ Nicholson, lot 037

Description

Nicholson slitting needle file #0 cut.  This file is .0575″ wide.   Slitting files are for creating narrow slots like in a screw head and only the narrow edges have teeth.   New, from master carton so no packaging.

Swiss style needle files and riffler files use a system of 00, 0, 2, 4, & 6 for the coarsness of the teeth with 00 bing the coarsest and 6 the finest.

Any file will work with steel, aluminum, wood, etc., though the finer toothed ones will tend to load up the teeth more especially with softer materials like wood or alluminum.

Start with a coarse file and if you like the surface finish you are done. If not, go to the next finer one, etc. Just like using sandpaper.
