Getting The Best Out Of Your Metal File

Types of file

Tang - designed to be inserted into a handle for the file Heel - also known as the shoulder, connects the tang to the file Teeth - the cutting ridges on the file's surface Side - the surface of the file Edge - the edge of a file is either round or square and will sometimes have teeth cut into them for filing. Usually one edge will have no teeth and is called a safe edge Back - the rounded side of all half-round files Length - the distance between the heel and the point of the file

Know your cut

There are three main grades of cut to a file: Bastard - coarse, heavy weight teeth for rapid and initial stock removal Second - medium weight teeth for moderate stock removal Smooth - fine teeth for light stock removal and smooth finishing

Using your file

Before you start filing it's important to hold the work securely. Here we have used the Axminster Trade Vices Engineer's Vice.

1. File one way Your metal file will only work on the away stroke, use both hands to hold the file and apply even pressure.

2. Lift file clear of work on return stroke Your metal file will produce a better finish and last longer if you remove the file completely from the work.

3. Draw filing Any type of single cut metal file can be used to produce smooth square edges.

4. A clean file Pinning or clogging of a metal file can cause a rough scratchy finish to your work and damage the teeth of the file. Use a file card frequently to keep your file at its best.
