Size of the blade
The size of the circular saw can be understood by measuring the diameter from side to side.
The bladed diameter can be found on the saw itself or on the blade. You can check either one to know the correct size of your blade. If you cannot find the size you can simply remove the blade and measure form side to side right up to the center to find the correct size. The arbor diameter also needs to be established. This is for the hole in the center of the circular blade that needs to fit in perfectly on the arbor of the circular saw. This can also be printed on the saw or surface of the blade. In case it is not, it can be measured by measuring the diameter of the arbor hole. These measurements must be carried out properly so you can find the right sized new blade to go with your circular saw.
The structure of the blade you need will depend on the functionality of the saw. You need to know the purpose of your use and choose a blade structure accordingly. A simple way to understand this can be by understanding the number of teeth your blade has. More teeth can help to provide a clean and more precise cut whereas blades with lesser teeth can be used to cut roughly. There are different kinds of teeth structures available for cutting specific surfaces. If you need a saw for general purposes you can go for moderate number of blades. For cutting finer surfaces with increased precision more number of teeth can be considered for the new blade.
What kind of a blade do you want?
Once you have narrowed down to the size and structure of blade you want to go for, the next step is selecting the kind of blade that can be the best choice for your use. You can start by thinking about the surface that needs to be cut. Some types of blades especially used for cutting wood include cross cut and rip cut blades. There are other kinds of blades which can be used to cut metal and other surfaces if you have a specific use in mind.
A rip cut blade consists of very few teeth. Generally, this amounts up to less than forty teeth. This can be a good choice for a chopped up style of cutting. These teeth are usually flat from the top and will not provide an advanced level of precision. If the use is very rough and that fulfils your requirement this can be your choice.
A cross cut blade has more number of teeth usually going up to more than forty in number. These are v-shaped and can benefit for an increased accuracy while cutting. You can also opt for a combination blade which has both rip and cross cuts for a versatile functionality. You can use the cuts selectively here for different purposes. Other kinds of blade are also available for cutting into a variety of surfaces. If you desire to cut metal or any other surface you can opt for a blade made to endure that specific material.
Once you have all these questions answered and you requirements are met, you can get to the actual task of changing the blade.
Follow the simple steps above to change the blade on your Dewalt circular saw. The use and functionality can guide you towards the blade type you want to use. Based on these guidelines select your perfect blade and replace the old one in a few easy steps!
