Nowadays, cutting many materials such as wood, masonry, plastic or metal is easy as we have a circular saw with us. The Circular saw was invented in the 18th century but it gained its fame in the 19th century when everyone started to use it and saw its various advantages. The circular saw has different kinds of blades and each blade is manufactured for a specific material. The rotatory nature of the circular saw needs more power but it cuts way faster because the teeth are in constant motion. Here, in this article, we will be discussing what is circular saw? What is the Best Circular Saw? How do you put a blade on a circular saw?
It is a machine or in other words, it is a power saw which uses discs or blades to cut down materials by the rotatory motion of the blade in a constant circular motion. It can be used in straight lines on pieces of lumber. Besides, they have heights and bevel adjustments.
What Are The Types Of Circular Saws?
There are different circular saws for different jobs. A few of them are listed below:
How To Choose The Right Circular Saw Blade?
A motor that draws below 15 amps comes with a 7-inch blade. Many tools stop its blade automatically when the trigger is released. The most important saw feature is the blade that is installed. The same may also cut concrete or any kinds of other materials but it needs a correct blade which is made only to cut that specific material. So here is some information that will help you choose the right circular saw blade.
1. Wood Cutting Blades
There are many types of wood cutting blades but all of them fall into two categories. Construction blades and plywood blades. They have structural differences between them. Construction blades with fine cutting skills have forty or more teeth. A blade that has twenty to forty teeth are designed for basic carpentry work where a smooth cut is not essential.
The teeth of this kind of blade have deep gullets to remove any wood chips or sawdust. If you are doing any rough work then the quality of the cut does not matter much but when you need a cleaner cut then the board should be cut from the backside. As the blade cuts in a clockwise direction so when the sharp edge enters the material, it results in a clean cut. On the other hand, plywood blades have many small teeth and because of these small teeth, the cut on both sides of the material is cleaner. Plywood also can be used to cut laminate.
2. Masonry Cutting Blades
You may have doubts that can a primary circular saw that was able to cut only woods can also cut metal or solid type things. Well yes, it can as I told you before it is not the saw that cuts, it is the blade. Masonry blades are toothless and are made up of fiberglass-reinforced carbide abrasive.
For masonry cutting blades there are two categories of blades. One is the coarse version of soft materials like brick, concrete block, and limestone. Another type is for harder materials like concrete, marble, granite, and all types of grazed ceramic type. But be careful because these cuts are extremely noisy and dusty thus always wear eye protection.
3. Metal Cutting Blades
Metal cutting blades are made of different materials which reduce the chance of shattering when cutting very hard objects. You can cut copper tubing, aluminum siding, aluminum flashing, and most other types of ferrous and non-ferrous metals with a metal cutting blade. But the blades are not interchangeable.
4. Plastic Pipe Cutting Blade
A wood-cutting blade with forty or more teeth works very well for cutting plastic pipes. The only thing you need to be careful about is the speed of the cut. The slower the cut, the safer you are. So don’t force your way through the pipe by the cutter.
5. Acrylic Sheet Blades
some plywood cutting blades are recommended for cutting through acrylic panels. But the results are unsatisfactory most of the time. straight cuts with a circular saw and fine blade can work if the panels are clamped in the correct place. Just cut it quickly with a smooth and slow pushing motion.
How Do You Use A Circular Saw For Beginners?
- Take safety precautions initially. Wear eye and ear protection.
- Adjust your blade so if it expands the amount of length you want.
- Check the blade guard and see if it is functioning properly.
- Attach the cutter to the work surface and use both hands to guide the saw.
- Now start the saw and move it through the material you want to cut.
- Keep pushing the blades through the material until the pieces fall.
- If you are cutting plywood or other larger pieces, you can attach a 1X4 blade to the workpiece. Make sure it is straight and even so you can get the best cut across the plywood.
How To Replace Your Circular Saw Blade?
Many of you do not know how do you put a blade on a circular saw or replace it?
Now I will be telling you some easy steps how do you put a blade on a circular saw? And how you are going to replace it?
- Unplug the saw and turn its power off.
- Press on the arbor lock button and rotate the blade until the locking mechanism engages.
- To open the nut, turn the wrench, in the same direction as the blade cuts.
- Pull back the saw’s upper blade guard and remove the blade.
- Put the new blade in the saw’s arbor making sure that the face of the blade’s teeth falls towards the direction of cutting.
- Then make the arbor nut tight again, but make sure it does not get too much tightening, or else you can’t replace it with another blade.

How Many Teeth Do I Need On My Circular Saw Blade?
You need a different number o teeth for cutting different types of materials. For example, if you want to cut veneered plywood and melamine then you would have needed 60 or 80 teeth blade. But MDF needs cleaner cit, so for a clean-cut 90 to 120 teeth are needed.
There are some basic techniques to use a circular saw and some easy steps about how do you put a blade on a circular saw? And I have tried my best to explain all those techniques and steps in my article. Hope that after reading this article you will feel a lot easier and comfortable when using a circular saw and during changing the blade of the saw.
