There is a need for you to know how to sharpen a circular saw blade. After all, it is not proper to let the blades get dull after several times of use. Among all the parts of the saw, the blade is the one that needs a lot of caring. If you really want to extend the lifespan of this tool, then sharpening its blade is highly necessary.

You will know that your blade is already dull if it is having a hard time in cutting. You should know this by yourself. Specifically, the difference between a sharp and brittle blade is too apparent.

Many users would just tend to buy a new blade if in their current one gets dull already. However, we do not advise you to do that. Using these tools should be cost-efficient. If it can be repaired, you should repair it. Avoid unnecessary expenditures. Or else, you won’t really see the value of your power tools.

With the right tools, you can sharpen the blade of a circular by yourself. Here are the proper steps to do it.

How To Sharpen A Circular Saw Blade

Materials you need

  • Marker or Chalk (Should be washable)
  • A Bench Vise
  • Handled File Set (Three pieces preferably)
  • A strip of wood (300 mm long; 8 mm thickness)
  • Socket set (Heavy duty)
  • Painters brush (25mm + preferably)
  • Wire brush (You will need a lot of this)
  • Jig

Cleaning materials

  • A pair of gloves
  • Rags (for cleaning the area and the blade)
  • G clamps
  • Petroleum jelly

Initial Preparations

  1. Before starting, you should secure your safety first. Making sure that the circular saw has no power is important. You don’t want the motor to run while you are disconnecting the blade. It can pose potential harm to your hands.
  2. Take the thin strip of wood and clamp it between the saw bed and the tooth. Doing this prevents the blade from accidentally spinning while you are removing the bolt that holds it.
  3. You will also the help of a jig in the sharpening process. A jig is a 300mm baton that has a short piece of wood attached to its end. A coach bolt, washer, and wing nut will also help in attaching the blade to the stick. With all of these present, you can keep your blade steady while you are sharpening it. Just flick the wing nut if you want to rotate the blade to sharpen its next tooth.
  4. Take your soft brush and dip it to your petroleum jelly. Brush the entire body of the blade and let the compound sit there for around 30 minutes. Doing this aids in breaking the resins in the teeth of the blade.
  5. After 30 minutes, start clamping the blade in the jig. Next, use a WD40 cleaner and wire brush to clean the blade. When you are brushing, you should begin from the inside then out. Specifically, the cleaning motion should be like of a CD. Soak a rag and rub it against the blade so that you can remove the residues and other fine powders. Moreover, you should not be scared brushing the teeth portion!

Sharpening Process

  1. You need to use your chalk and mark the upper portion of the blade. In this way, you will know if you have already finish sharpening the entire disc. Double sharpening is not a good idea, by the way. Aside from the fact that it can take your time, it can also harm the quality of the blade.At this point, you will notice that between two teeth, there is a bevel that is facing towards you. Take your file and clutch it at a 20-degree angle (based on the bevel). Afterward, give the bevel of the first points four simultaneous strokes. Use a consistent up and down motion to do this. You can quickly notice if you did it successfully. If not, just do more stroke again.
  2. Always pay attention to the bevel. Specifically, you should skip one point and just go to the succeeding beveled edge instead. You should do this because the bevel is present on every other tooth. Just continue doing this process until you can go around through the entire blade disc. Moreover, the strokes should be equal with the first one.
  3. Once you complete a single rotation, do the same process once again. This time, you will still need the help of the mark to know where you have started.
  4. After this, you will need to start filling the blade. Specifically, you have to file each of the tips of the teeth. At this point, you are only required to run the file back and forth, instead of applying multiple strokes. Always aim the front edge that you can see on the blade point. Obviously, you have to do this on all of the teeth of the blade.
  5. When you are done, you can already clean the saw blade using a clean rag. Remove all the residues and other remaining debris. Your blade should be good as new now!

Conclusion

Knowing how to sharpen a circular saw blade is essential knowledge for the owners of this tool. Even the professionals in the industry would recommend learning this skill. After all, nobody wants to waste money on constantly buying blades when the current one gets dull. Of course, it is not economical, and it doesn’t relish the DIY spirit in you!

However, sharpening your blade from time to time will eventually lessen the integrity of the teeth. Specifically, the teeth will grow smaller because of constantly shedding new layers. Therefore, in your next sharpening, make sure that you will do deeper gullets that the previous one. If you don’t do this, the shape of the blade will look distorted. When this happens, you have no choice but to buy a new one again.

In sharpening, always be careful with the blade. Even if it is dull, it has still the capacity to wound you. As a piece of advice, wear a pair of gloves for a foolproof work process!

How To Cut Wood With A Circular Saw

Circular saws are a great help in the workshop or the job site. It can assist you in cutting and ripping materials. Aside from wood, it can cut harder objects too, such as metals and some construction materials. However, most of us will agree that it wood is the first thing that comes into our minds every time circular saws are mentioned. Therefore, how to cut wood with a circular saw is truly essential.

Knowing how to use a circular saw is necessary for the efficiency of your work. Moreover, it can guarantee your safety, too!

Using a circular saw for wood is quite easy. Just take the time to practice, and you can perfect it eventually. Here are the steps for cutting a wood with a circular saw!

How To Cut Wood With A Circular Saw

  1. The first thing you should do is supporting the material that you are going to cut. This time, it is going to be a plank of wood. You should do this so that you can prevent the blade from interacting with the objects beneath the wood. Specifically, you should place concrete slab or board while you are cutting. When it comes to that, you might need a sawhorse more than a circular saw.
  2. Afterward, you should mark the wood that you are going to cut. You can use a measuring tape to measure the length of the cut that you are going to make. Use a square (steel square or tri-square preferably) to mark the entire path in where the blade will traverse. You should remember that the marking should be straight.
  3. Adjust the blade of the saw so that it would match the depth of the cut. Do not expose too much of the blade because it can delay the cut. For example, if you are going to cut a 40mm wood, then the blade’s depth should be around 45 mm only. Through this, you can minimize the potential kickback of the blade, which is dangerous, by the way.
  4. While cutting, ensure that your blade guard is properly functioning. Specifically, the guard should go back right in place every time you pull the saw. Moreover, it should slide up also as you push it back to the wood. After you use the saw, the blade guard should be in a down position. In this way, you can prevent unwanted accidents on your workshop.
  5. Gaze down the right side of the blade of your circular saw. In this way, you can align the blade properly to the mark that you made in the wood.
  6. After this, look at the face of the saw, specifically to its two guide notches. The first one (the right hand) is your guide when you are cutting the wood at a standard position. The second one (the left hand) is used if you are going to cut at 45 degrees base angle. Mark this notch using a pencil.
  7. When everything is set, you can start cutting the wood. Let the saw sink it to the wood while maintaining a steady but gentle hold. Always have your eye check the guide all the time. In doing this, you can ensure that you are in proper looking position. Specifically, your body should be slightly adjacent to the mark. If your circular saw doesn’t have a dust collector, this position is beneficial for you. This angle is sufficient to keep the saw dusts from reaching you!
  8. While cutting, you should also pay attention to the base of the saw. The base should always be flat. As much as possible, it should not have any elevations to the wood. Or else, it can affect the precision of your cutting.
  9. You should exert force in pushing the circular saw to the wood. It doesn’t matter if your saw has a powerful no-load speed. You should know that the saw doesn’t move by its own! However, you should not also push too hard because it can reduce the speed of the blade.
  10. Always be cautious about your lower blade guard. As you pull the saw on the wood, it should return to its original condition. While you are working, some large debris can bind the blade guard, which prevents it from lodging.

Conclusion

Now that you know how to cut wood with a circular saw, we expect that your productivity in the workshop will increase. To be honest, cutting wood using a circular saw is easy. It does not require technical skills in order to perfect. All you need is the best circular saw, and you are ready to go!

Moreover, do not forget to exercise all the necessary safety precautions. After all, the severity of harm that this tool can inflict is quite grave. A trip to the hospital is the last thing that should happen to you!

Many of the circular saws today have base plates that can tilt from 90 degrees to 45 degrees. This design is necessary if you want to make miters and hip-roof rafter cuts.Aside from that, standard base plates have thumbscrew to loosen its bolt. Through this, you saw can keep its blade at the right angle, based on the cut that you are doing.
  • Blade – A circular saw would be useless if it doesn’t have a sharp fang to make the cut. Typically, you can adjust the blade of this tool so that you can adjust its depth. Specifically, it ranges from 0.3 cm to the maximum cutting capacity of your saw.
  • Ripping Fence – This is the component of a circular saw that acts as the guide of the blade if it is making a ripping cut. With this feature, you can expect that your cuts are straighter and smoother.
  • Dust Ejector– Only a few circular saws possess this part. Its primary use to prevent the dust and debris from getting into the face of the user. Moreover, a dust ejector also blows these residues from the mark that you are cutting.
  • Laser Tracking Light – Once again, not all brands of circular saws have this feature. This laser further improves the precision of your cuts by striking a red light to the path of the blade. You can also purchase this component separately (in a retrofit) if your circular saw is not engineered to hold this accessory.
  • Blade Guard – The blade guard is an essential part of a circular saw. You should remember that your safety should be your utmost concern. Specifically, the blade guard is divided into two parts: the fixed guard on the top and the floating guard that rolls away when you are pushing your saw to the material you are cutting.
