The Best Dado Blade Set Option


Dado blade sets are designed to make three-channel cuts by using two outer blades to cut through a specified wood thickness and using inner chipper blades to strip away the inner wood to a smooth and splinter-free surface. These types of stacked dado blade sets are best for making the most precise cuts and work much faster than using a handheld router saw. The number of teeth, available cutting widths, durability, and size compatibility are all important features to consider. As long as your table saw can safely accommodate a dado blade set, then choosing the best dado blade set can help you power through your joint-cutting jobs.
