Compound mitre saws tend to be suited to people who make angled cuts often in work such as when making picture frames, crown mouldings or boxes. They may also be used professionally on construction sites where materials need to be specifically angled such as roofing.

We have listed out some other benefits below as to why you should use a compound mitre saw -

How Do I Use a Compound Mitre Saw?

Now we know what a compound mitre saw is, its essential parts and why you should use one, we have put a basic step by step guide below which will teach you how to use one of these machines efficiently as a beginner.

Step One - Select The Right Size & Turn It On

Before you can start to use your compound mitre saw properly you should make sure it has enough power and size for the job, your blade size should be big enough for the width of what you are about to cut and the machine should have enough amps of power for the work required, for a more powerful job, use a more powerful compound mitre saw.

If your compound mitre is the right size you can begin by switching it on and adjusting the base of the saw and head according to the angle or bevel that you want to cut. Don't press the trigger handle power until you are ready to cut the material.

Step Two - Mark The Wood & Press The Trigger

Always mark where you want to cut on your wood with a pencil, remove the blade guard on your machine and lower it so as the teeth are exactly where you have marked for the cut, make sure it is against the fence on your machine.

Keep your hands away from the blade after setting it up.

Step Three - Get Cutting!

Now you have turned your saw on, let it cut the wood as it reaches its highest speed itself, for repeating long cuts use an adjustable stop and for shorter ones use a line on the guide. Never lift the blade once it has stopped until it stops turning.

Step Five - Keep Big Pieces Supported And Experiment

A compound mitre saw is pretty easy to use once you get the hang of it but you should always remember to keep large pieces of stock supported with blocks and keep shorter pieces of wood clamped. Experiment with different angles and bevels so as you can get an idea of what fits.

Safety Tips For Using a Compound Mitre Saw

Compound mitre saws are one of the safest woodworking tools on the market, but this doesn't mean you shouldn't take any precautions in case of an accident, you should also remember you are working with a powerful machine that has a fast powered saw, so it's better to be safe than sorry!
