Using the DeWalt DW812DADO dado saw blade set is quite straightforward. First, select the appropriate combination of outer blades, chippers, spacers, and shims according to the width of the groove you want to cut, which can range from 1/4 - inch to 7/8 - inch. Then, install the set properly on your saw. When using it, make sure to wear safety goggles and other protective gear. Don't force the blade through the material; let the blade do its job at a normal pace. As for maintenance, after each use, clean the blade with a soft brush to remove any debris. The heat - resistant non - stick coating helps prevent gumming up, but if there is any build - up, you can use a mild cleaning solution. Also, when the carbide teeth start to dull, you can resharpen them to extend the life of the set.
