What is spindle lock on circular saw?

Not only table saws, but drills and circular saws are also equipped with a spindle. The spindle lock has proven to be a very efficient and useful feature and there are many reasons why you need it. So, what exactly is a spindle lock on a circular saw?

The spindle lock is designed for one thing – to stop the blade from turning so you can safely remove it. Once you push the button that activates this feature, the spindle lock blocks the blade and you are ready to start unscrewing the nut that holds the blade on.

Do you really need a spindle lock?

Like it or not, almost every circular saw is equipped with it. It is widely known that this feature can help you with faster, and also safer blade removal.

However, you will survive if your saw doesn’t have it. It isn’t the end of the world, but you will notice that it is much tougher to tighten or loosen the nut.

How to tighten the blade without a spindle lock?

Every time when you are going to touch the blade with your hands, the first thing you will need to do is to unplug the saw.

If you need to tighten the blade, tight the blade with your fingers as much as you can. Next, use a screwdriver and set it across the fence so the teeth of the blade are blocked to move by the screwdriver.

Some blades have holes in them, so if you could put the screwdriver in one of those holes that would be much safer as the risk of the screwdriver slipping would be minimal.

This should be enough to get the arbor bolt to pinch the arbor on the blade and you will be ready to start cutting.

How to change the blade on a circular saw?

Which type of power source does your circular saw use? If it is a corded saw, make sure you unplug it. If you use a battery, remove the battery before you proceed.

On the front part of the tool, you will notice a push button somewhere. That button activates the spindle lock and the blade will lock in place. In case the blade is covered with the blade guard, remove the guard as well.

Once the blade is not moving, you can use the wrench that you get when buying the circular saw. You can use another wrench as well, but the one you get is the right size.

Loosen the nut, remove it, and the blade will be free so you can take it out. Put the new blade and pay attention to the position of the teeth.

Put the nut back and use the wrench to tighten it. This time, you will need to turn it into opposite direction of blade spinning.

Plug the circular saw, or put the battery back and you are ready to use it.

Although this seems easy, it is better to take a look at this tutorial for step by step explanation of what you will need to do.
