Circular saw blades put the power of your saw where it's needed, so the right blade is a key to the success of your project. Just as there are different saws and different project materials, there are different circular saw blades – each suited to a tool and a task. Learn how to find the right one for your work.
There are four important parts on standard circular saw blades:
Other features you might see on a circular saw blade include heat vents which aid in reducing vibration and an antifriction coating, which decreases buildup on the blade. A blade may also have a diamond knockout you can remove to allow you to use the blade on a saw with a corresponding shaft.
In addition to the standard toothed blades, there are also continuous rim blades that do not have the typical tip / gullet configuration. Blades that cut materials such as concrete, brick and tile often have a continuous rim.
The materials from which saw blades are manufactured play a significant role in the life and performance of the blade. There are several material types you will commonly see:
Some circular saw blades are suited for stationary tools like table saws and compound miter saws, while others are suited for handheld circular saws. Know which blade your cutting tool will accept and make sure the blade you are considering is correct for the tool you'll be using.
It's also important to know what kind of material you'll be cutting and to match the material to the capability of the blade. In addition, some blades are suitable for dry cutting only while some are suitable only for wet cutting. Others are appropriate for either wet or dry applications.
Some examples of blade types and uses are below. Always follow the saw and blade manufacturers' instructions for use, safety, compatible blade diameter for the saw and materials you can cut with a blade.
