How Often Should I Replace My Diamond Blades?
A decent diamond blade usually lasts a long time. However, if the blade is subjected to a lot of pressure and isn’t used properly, it can wear out quicker than expected. But how do you know for sure if you need to replace your blades? Let’s take a look at some of the signs.

Signs of Wear and Tear
- You can see the blade’s core
If you can see the core of the blade, it means that all the diamonds are used, and it’s time to replace your blade. - Your diamond blade is cutting slower than usual
This is a sure sign that your blade is worn out. If you keep using the blade before replacement, it will stop working altogether.
- The blade is damaged
If you use a cracked or damaged blade, it can cause an accident. Even if you see just a small crack in the diamond blade, be sure to replace it ASAP. - Your saw is making thumping noises
A blade that is loose or needs replacement will make thumping noises if you continue to use it. Either way, check to make sure it’s not worn out. Also make sure that your blade’s arbor hole matches your saws arbor. - The blade is smooth
Not only will your blade not cut properly when it needs replacement, it will also look smoother due to less diamond grits in the bond. - The metal teeth are worn
The blade’s metal teeth wear down eventually, which is a sign that the blade needs to be replaced.
Inspecting Your Blade
If you're having cutting issues, a thorough visual inspection of your blade can help determine if it's time to replace the blade. Sometimes, you don’t need to replace the blade altogether – it just needs to be run through an abrasive material to expose new diamonds underneath.
Make sure the blade is mounted properly and check all the blade collars and belts. Additionally, read your owner’s manual to familiarize yourself with your blade and the parts associated with it.
It’s a good idea to always check your saw before you operate it. Not only does it help to ensure safety and save energy, but it could also prevent having to replace your blade as often.
