Is your miter saw blade dull?

There is a simple way to check whether you need to replace a miter saw blade. You have to test it before you buy a new detail that can be quite expensive. Cut the wood and see whether the blade is still effective. Yet, there is a possibility you have to consider.

The old one might be just dirty. Even if you work only with the best wood, its pitch might still accumulate on the blade. The more you work, the bigger the layer of the pitch until you decide that the blade is dull.

Naturally, after some time, even a sharp blade will turn into a dull one under the layer of the wooden pitch since it corrodes the metal.

This is why, before you remove a miter saw blade, you have to clean the blade and make sure that it is dull and not dirty. You need a cleaner specifically designed for blades. Before you start, disconnect the tool from the electricity.

Once you clear it and wipe it with a clean towel, turn on the miter saw and check the blade on the wood. If the cleaning procedure did not help, you need to change it.

Changing saw blade: Step-by-step instructions

This is when you have to become extra cautious. If you don’t know the basics, it is better to learn them in advance. Read this guide, and if you need to refresh it in your memory or watch one of the useful tutorials with pictures, do it.

Usually, every saw comes with a manual, but if you lose one, that’s ok. You can google instructions for a specific miter saw. Here is a manual compatible with a vast majority of models:

  • Step 1. Before you do anything, check whether the tool is disconnected from the outlet. You can’t possibly start removing anything before you do it. This is a major step to perform.
  • Step 2. Now you can take out the Spindle Cover. Put the blade guard in the highest position. Detach the screw on the front from the cover. Let the cover go down from the back screw.
  • Step 3. You need to take away the blade. Do it carefully since it still might cut you. Press the spindle lock until you release it. If you have another model, and the spindle lock can’t be completely locked, you have to turn it with pressure, using a 10-mm wrench. If the thread bolt is left-hand, turn it to the right to unfasten it.
  • Step 4. Now you have to change the blade itself. Take a new one. You will have to repeat all your actions backward. Which way does a miter saw blade go? To find that out, pay attention to the arrows on the blade. They are pointing in the miter saw blade direction. Follow them to install the blade correctly. You might need to replace the bolt and washer. Turn the bolt to the left if you need to tighten it. Fixate the bolt using a 10-mm wrench. Don’t forget to put the spindle cover and lower the guard. The spindle lock must be disengaged before you turn on the instrument.

One more quick recommendation for you: your saw needs an adjustment once in a while. Just put the blade square towards the table, and its fence is square to this blade.

Pay attention to whether your saw blade is clean and don’t forget to wipe it with a towel after the job is done and you unplug the tool from the outlet.

Choosing the blade for your miter saw

2 Miter Saw Blades

If you have no idea which blade you should buy, you can simply use the old one as the source of information. Find the same model on the Web and buy it. However, if you want to upgrade your tool, you can also look for sharper teeth or even more solid material. Pay attention to the following aspects:

  • The material of the blade. Think about the purpose of the blade. Will you cut wood only? Which type of wood will it be? Since there are no universal blades, you might need to buy different types for various projects. No matter what the blade is used for, the material must be of high quality;
  • Type of cuts. Decide which cuts you need. Usually, it depends on the work you do. The more cuts it does, the more accurate the line you receive, but the longer it might take. Check out the number of teeth. The blades with a lower amount of teeth make rough but fast cuts;
  • Native blade to the miter saw. Some miter saw developers release blades specifically for their models at least once a year, while others create universal tools for different blades. Check out whether there is a native blade for your miter saw on the market since it is more suitable for the instrument;
  • Price. The price varies based on the material, developer, and even the purpose of the blade. The steel blade is the classic one, and also the cheapest option. Yet, it is good only for softwood. The high-speed steel blade is perfect for hardwood, but it is a little bit more expensive. The priciest option is the carbide-tipped blade, but it has a higher service period.

When should I change my miter saw blade?

Once you notice that the blade does not cut the wood or any other material you are working with, you have to replace it. Before you do it, make sure that the blade is not dirty, and this is not the reason it does not work properly.

You can also change the blade if you need to work with another material or need to make other types of cuts.
