Tools and Materials you will need can vary depending on how old your existing grinder is.

Why should I bother sharpening a carbide circular saw blade?
A well-maintained circular saw will provide you with a safer and more efficient working experience. In certain cases, it can also prolong the life of your blades. For instance, a carbide blade may last over 50 times longer when it is being used on a sharpened blade.
Don’t think that sharpening a circular saw blade is completely essential, however. Circular saw blades that are not adequately maintained may pose some danger to you and your colleagues. They can also cause more damage than good due to their increased friction on the material being cut: they will become hot and wear down very quickly as a result of this additional friction.
In general, a sharpened carbide circular saw blade will help you to produce cleaner and more accurate cuts through tougher surfaces. In addition, it will also increase your productivity. You can complete more assignments in less time with a well-maintained blade, as opposed to one that is not up to scratch!

If you are interested in sharpening your own circular saw blades, then there are some important things to consider first. Most importantly, it is vital that you wear the appropriate safety gear at all times. This includes wearing thick gloves and welding goggles or glasses before you begin working on the blade. You should also ensure that the area where you will be working is clear of spectators.
Now, for this task, it should go without saying that using a machine should be left to professionals who know exactly what they are doing! Attempting to sharpen a carbide circular saw blade by yourself could prove extremely dangerous – not just because of the inherent dangers with blades but also because you could easily damage your own machine.
With this in mind, you should take the blade to a professional service center if it is not sharp enough for your needs. Many of these services offer free sharpenings for customers who use their machines, so do check beforehand. If you are not comfortable with taking your machine out, however, then there are some simple ways to sharpen circular saw blades yourself.
For instance, using manual tools such as files and stones will allow you to give your blade that special touch. This method is extremely easy but does take up significantly more time than having it done by professionals! You can also buy attachments for certain types of grinder motors attaching them directly to the tool itself through an arbor. This way, you could save quite a lot of time!
How to sharpen a circular saw blade by hand?
First, you will need to purchase the necessary tools for this task. Some of these include files and stones that look like this. You should then ensure that your machine is switched off and unplugged from any power sources. You should never attempt to sharpen a circular saw blade when it is on or plugged in. Once you have done this, use the stone and file to remove any excess material from your blade’s edge.
You should see sparks flying off of the cutting surface as you do so if not, then you will need to do this task again! This procedure will remove any uneven blunting of the cutting surface, which would otherwise cause a decrease in performance.
A word of caution
Do not apply too much pressure on the blade when filing it with a stone or file – this is another factor that can cause early damage to your circular saw blade. You should also ensure that you have a steady hand when doing this. Your blade will need to be lubricated after being sharpened – do not forget to apply the lubricant before plugging in your device.
How to sharpen a circular saw blade by using a grinder?
Using a bench grinder or angle grinder is the quickest and simplest way to sharpen your circular saw blade. However, it can be very dangerous and often results in damage to both the tool and wielder! This task should only be done with extreme caution. To do this, you will first need to attach the circular saw blade using an arbor or spindle. You should then secure your metal bench grinder in place so that it cannot move about accidentally.
You should then set the angle of your metal grinder to a 30-degree angle or thereabouts. You should also make sure that you have a steady hand when doing this if not, you could easily damage your machine. Once this has been done, you can use a cloth to apply a liberal amount of grinding compound on the surface of the grinder.
Conclusion: As you can see, it’s not difficult to sharpen a carbide circular saw blade as long as you have the right tools and follow these simple steps. Be sure to practice on an old blade before trying it on your expensive new one. And always be careful when handling sharp objects. We hope you found this guide helpful.
