Why every jeweller and craftsperson should own a set of swiss needle files

 

What Are Needle Files?

Needle files are small hardened steel files that are available in different profiles and cuts. They are used for filing, shaping, deburring, setting, chamfering, smoothing and finishing metals, wood, plastics, and polymer clay.

Needle files come in various different profiles: Round, Half Round, Barrette, Pillar (Flat), Warding, Knife, Crossing, Square, Oval, Slitting, Crochet and Three Square (often referred to as Triangle). Each shape serves a different purpose. More about the various shapes and what they do further on in this article.

Needle files consist of cutting 'teeth'. The cut is indicated on a scale ranging from 00 that is the coarsest, to 6 that is the finest.  Each cut has a certain number of teeth per square centimetre.

How To Use a Needle File And The Common Mistakes when Using Them

A common mistake when using needle files is to use them in a sawing action, back and forth.  Needle files work in one direction and must be used in a push action, filing gently away from you in one direction. 

If used incorrectly the teeth of the file will round off and dull quickly making them unusable. 

Diamond needle files differ from metal needle files in that they can be used with a back and forth, sawing action, if you would like to learn more about diamond files and how to use them, have a read of this article:

What Do the Different Shapes of the Needle Files Do? 

Pillar 

The Pillar file is a flat file with a wide, rectangular cross-section. There are teeth on all four sides cutting down towards the tip. This is a great general purpose file for working on flat surfaces, filing ends away. An absolutely essential needle file. 

Square

Again with teeth on all four sides cutting towards the tip. The square file tapers gradually down to a fine, sharp point giving you the advantage of 90 degree angles, great for filing corners or up against posts. There is also the very fine point and the corners, so a very useful file.

Three Square (Triangle)

Vallorbe Swiss needle files have what they refer to as a three square file which to you and looks like a Triangle. They make a range of different triangular shaped files and because this particular file has three sides all with equal angles they call it a three square.  Like the square file, it tapers to a fine point, so you can use the point, the flat sides and the nice sharp edges.  This file is great for filing grooves. When you bend a sheet of metal, the three square is great for smoothing out the marks left behind. 

Round

This has a circular cross-section and the teeth are all the way round it, 360 degrees cutting towards the tip with teeth at the very tip. This file is wonderful for getting into tight, intricate areas like inside jolt rings or inside clasps and perfect to use as a reamer for enlarging and opening up holes. 

Crossing

These were originally designed for filing crossings, the spokes inside clock gears. The curved shape is perfect for the inside of rings and for filing and smoothing any small curved shape. Crossing needle files are one of my personal favourites.

Barrette

Barrette comes from the French, meaning burr-ette or literally a small burr.  It has a triangular cross-section but  the back has no teeth, so there is no danger of filing any other surfaces.  This means you can get right up to an edge without any danger of marking it. Perfect for cleaning up solder joints on flat surfaces or for getting into really tight corners, without any danger of filing the wrong side. You might also see these referred to as safety back files because the back is safe. i.e there are no teeth on it.

Warding

Warding files were originally designed for use by locksmiths to work on 'wards' in keyholes, or notches of keys. For jewellers and general metalsmiths they are ideal for opening up square holes and filing square corners as well as creating slots and notches.
