What is dado blade?

A dado blade is a type of circular saw blade that is used to cut grooves or dadoes (wide channels) in wood. It consists of two circular blades with chippers in between, allowing for multiple cutting blades to be stacked together to create a wider cut.

Dado blades are commonly used in woodworking and carpentry to create joints, shelves, and other structural elements in furniture and cabinetry. They are especially useful for creating strong and precise joinery, such as dado joints, rabbets, and half-lap joints.

When using a dado blade, it is important to adjust the width of the dado to match the thickness of the material being cut, as well as to ensure that the blade is securely installed and aligned properly on the saw. Safety precautions should always be taken when using a dado blade, including wearing eye and ear protection, and using a push stick to guide the material through the blade.

Dado blades come in a variety of sizes and configurations, including adjustable dado blades that allow for customizing the width of the cut. They can be used on table saws, radial arm saws, and some handheld circular saws that are equipped with a dado blade attachment.
