Because of their similarity, dados and grooves are often referred to as 'slots'. Rabbets are somewhat different – we'll look at them shortly. Likewise, what is the difference between a rabbet and a dado? As the dado set spins, the two outside blades cut the dado walls and the chippers remove the waste material in between and smooth the bottom of the dado. Likewise, what is a dado blade used for? A dado set or dado blade is a type of circular saw blade, usually used with a table saw or radial arm saw, which is used to cut dadoes or grooves in woodworking.

In this manner, why are dado blades illegal?Īs already mentioned dado blades are illegal on UK (EU) table saws because in order to use them the guard and riving knife have to be removed, and is therefore unsafe. A router can be used to cut dadoes, but a circular saw can also be just as effective. These are cut using a dado blade on a table saw which removes the wood to create the channel. A dado is a square-walled, flat-bottom channel cut across the grain of wood, that another piece of wood will fit into snugly.
