With so many different types of file available, these simple tools have a huge number of applications in the world of DIY – but what are the alternatives?
There are a few options available to DIYers who are looking to shape, deburr, sharpen or finish materials in their workshop, which are compared with files below.
Grinders
Grinders are the go-to tool for most DIYers who are looking to shape a piece of metal or sharpen another tool.
Working on the same principle as files, grinders consist of a coarse wheel that rotates at speed and wears down any object that comes into contact with it. As they are powered by electricity, they require little physical effort to operate.
They offer some degree of customisation, as it’s possible to choose the coarseness of the grinding wheel that you use.
They are, however, more expensive than files and need to be attached to a bench in your workshop, so you will need to make sure there is space.
ADVANTAGES
DISADVANTAGES
Require little effort to use
Wheels available in different degrees of coarseness
Can achieve results much more quickly than files
Expensive in comparison to files
Cannot be used to create shaped grooves or to work in internal angles
Requires permanent bench space in your workshop
Angle grinders
A hand-held version of the grinder – the angle grinder – is much more customisable and can be fitted with a number of different grinding wheels.
These wheels are suitable for use on wood, metal or plastic, for shaping, sharpening and finishing.
Again, they work more quickly than files, but are considerably more expensive.
ADVANTAGES
DISADVANTAGES
Customisable to a high degree
Can cut, shape, sharpen and finish
Can be used on a huge range of materials
Can achieve results much more quickly than a file
Expensive in comparison to files
Larger than files, so not as useful in confined spaces or for detail work
Routers
If you are planning on creating complex shapes in two dimensions, a router may be an alternative to consider.
Routers are power tools designed to create grooves or cut shapes with a rotating cutter. They can cut around an outline scribed onto a workpiece in just a fraction of the time it would take to file it to shape.
Routers are capable of cutting three dimensional shapes, but this is sometimes not as easy as with a file.
They can be set up to work on wood, metal, plastic and a range of other materials used in DIY.
Compared even to a set of files, a router can be a considerable investment, so you may want to consider how much use you would have for one before committing to buy.
ADVANTAGES
DISADVANTAGES
Capable of shaping material very quickly
Can be used on a huge range of materials
Requires permanent bench space in your workshop
Considerably more expensive than multiple files
Air files
An air file is a pneumatic tool that is powered by compressed air. The purpose of the tool is to drive a file bit forwards and backwards to simulate the action of cross filing at a much faster speed.
For more information on cross filing, see: What is cross filing?
Air files tend to come with around four different file attachments. These are usually flat, half round, round and triangular.
See: What are hand and flat files?, What are half round, ring and marking files?, What is a round file? and What is a three square file?
To use the tool, the file bit must be secured tightly, and the air file itself must be connected to an air compressor. Once activated, the file will move forwards and backwards at a rate of around 50 times per second.
As you won’t need room to move your elbow, an air file is perfect for use in confined spaces.
Using an air file, you can remove material much more quickly than you would be able to if you were filing by hand.
However, the tool can be expensive on its own, and you will most likely need to buy other equipment, such as an automatic oiler and air filter, to make sure it will run smoothly. It will also only work with the file attachments supplied with it, and not with any of the other files in your collection.
ADVANTAGES
DISADVANTAGES
Produces results much more quickly than filing by hand
Files easily in confined spaces
Runs quietly
Comes with four different attachments
Incompatible with normal files
Requires an air compressor
Usually requires an air filter and oiler to ensure smooth running, which must be purchased separately
Expensive
Not suitable for precision work
Wood turning chisels
If woodworking on a lathe, a wood turning chisel is a better tool than a file for rapid removal of material to quickly shape a workpiece.
This still allows a high degree of precision and can create intricate shapes for the creation of chair legs or other cylindrical objects.
ADVANTAGES
DISADVANTAGES
Allows greater precision when working on the lathe
Cannot be used for finishing
More expensive than files
Only applicable to lathe work
Sharpening stones
Rather than using a file for sharpening tools, you can use stones as an alternative. Available in a variety of different levels of coarseness, stones can be used to make a tool razor sharp.
There are a variety of different sharpening stones, including oilstones, whetstones and water stones. The most important thing, however, is to check the grit (measure of coarseness) of the stone you will be using, as it will be integral to achieving the level of sharpness you are looking for.
Stones are best used in conjunction with either files or grinders to finish off the sharpening process.
ADVANTAGES
DISADVANTAGES
Can create a much sharper edge on a blade than a file
Will grind in both directions, allowing quicker results
Cannot be used for anything other than sharpening
Sandpaper
When it comes to finishing a piece of material, sandpaper is an excellent choice.
It’s cheap, easy to use and produces reliable results. You can find it with different degrees of coarseness, as with most other abrasive tools, meaning you can work towards finer sandpaper to produce exceptionally smooth finishes.
Sandpaper can be used on most materials, including metal.
However, its working life is much shorter than that of a file, as it is vulnerable to wear and tear.
