Dado Blade for Circular Saw Review
Dado blades, also known as stacked dado blades, are circular saw blades specifically designed for cutting wide grooves, rabbets, and dado joints in woodworking projects. Unlike a standard circular saw blade, which has a kerf (width of cut) typically around ⅛ inch, dado blades create a much wider cut by consisting of two or more thinner blades separated by chippers or spacers. These chippers determine the final width of the dado cut and can be adjusted to achieve the desired size.
Dado blades come in various diameters, typically ranging from 6 inches to 12 inches, to fit different circular saws. They are also available in different tooth configurations, with higher tooth counts generally offering cleaner cuts but requiring more power from the saw. Dado blades are constructed from high-quality carbide for durability and clean cuts in hardwood, softwood, and plywood.
When choosing a dado blade set, several factors should be considered. The diameter of the blade set needs to be compatible with the arbor size of the circular saw. The desired dado cut width will determine the required width of the chippers or spacers. The number of teeth will influence the cut quality and the amount of power required to run the blade set. Some dado blade sets come with a variety of chipper sizes, offering greater versatility in creating different dado joint widths.
Dado blades offer several advantages over using a standard circular saw blade for wide cuts. Firstly, they produce a much cleaner and more precise cut, reducing the need for additional sanding or cleanup. Secondly, dado blades help to prevent tear-out, especially when cutting across the grain of wood. Additionally, dado blades can be used to create various woodworking joints, including rabbets, dados, and slots, making them a versatile tool for any woodworker.
However, there are also some limitations to consider when using dado blades. Due to their wider kerf, dado blades require more power from the circular saw motor to operate effectively. Some older saws might not be powerful enough to handle dado blade sets, especially larger diameter blades or those with higher tooth counts. Dado blade sets are also generally more expensive than standard circular saw blades.
Overall, dado blades are a valuable addition to any woodworker’s toolbox for creating clean and precise wide cuts, rabbets, and dado joints. When selecting a dado blade set, consider the diameter needed for your saw, the desired dado cut width, the number of teeth for the preferred cut quality and required power, and the versatility offered by the set’s chipper options.
Dado blades can significantly improve the quality and efficiency of woodworking projects that require wide cuts or dado joints. By carefully considering the factors mentioned above, you can choose a dado blade set that meets your specific needs and helps you achieve professional-looking results.
