What size blade for Dewalt circular saw:

The size of the blade determines the diameter of your saw’s cut. The most common blades are 7-1/4″, 7-1/2″, and 8″. Blade diameters are measured by the number of teeth on it multiplied by two. For example, a 7-1/4″ blade has 13 teeth, while an 8″ blade has 16.

Most Dewalt circular saws accept either size blade. If you’re not sure what size your saw takes, then check out this helpful page to identify your model number. It should be noted that some models of 5 1/2″ circular saws use different sized blades than their larger counterparts.

For example, a 6-1/2 inch circular saw is commonly used in most construction jobs, but it can be cumbersome to use on smaller pieces of wood. A 7-1/4 inch saw would be the better choice for this type of work. You also want to make sure the bulk of your material will fit onto the blade for additional safety.


There are three types of blades available, and each has its pros and cons:


A bi-metal blade is more durable than a standard blade, but more expensive as well. These types of blades will cut through nails with ease, so they’re great for construction projects and other materials that may have nails in them.

However, these blades will not do the best job at cutting straight lines because they heat up quickly and can lose their sharpness after just a few swings. These blades also require some advanced knowledge to install properly. If you don’t correctly align the teeth on your blade when you put it on, then it might vibrate or run off track while you cut. See our blog post on aligning a circular saw blade for more information.


Standard blades are much cheaper than bi-metal blades, but they’ll wear out faster and won’t cut through nails as well. These blades are great for cutting plywood, hardwoods, or other types of materials that have no nails in them.

The one thing to note here is that because standard blades need higher RPMs in order to cut straight lines, you may experience a little bit of vibration when using them. However, there’s a quick fix for this problem: just grind your teeth slightly! This video shows how it’s done:


Tiles blades offer the greatest performance and longest life of all blade types. They’re typically last twice as long as standard or bi-metal blades, but they cost more than those two types as well.

These blades are made for cutting tile and porcelain , so they need to be able to withstand high temperatures without wearing out too quickly. If your construction project requires you to make lots of cuts in tile, then a tiles blade is the best option for you.

However, if you don’t plan on doing much work with tiles, then a standard or bi-metal blade might be a better choice because they’ll save you some money.


If you’re looking for a blade that can cut through materials other than what we’ve mentioned above, then you should consider getting a custom blade made just for your needs. You can order these blades through most hardware stores or blade distributors, and you’ll be able to find exactly what you need with their help.

So whether it’s metal, ceramic, Plexiglas, or some other material, just tell them the type of saw that you have and they will send out the perfect blade for your needs!
