If you are familiar with woods, then you should know how difficult it is to make an incision into one, especially hardwoods. Using a regular saw most times won’t do the trick, and that is why we have dado blades to make the task easier for us. Dado blades are highly recommended because they make smoother and more accurate cuts that the regular saw while saving us a lot of valuable time. Most professional woodworkers find dado blades helpful because, at some point, they will want to make grooves in a wood, to join two pieces of wood together, or for just decoration purposes. No matter the choice, it is almost an impossible task unless you have a dado blade to help you out.

A dado blade is a machine/tool that was designed mainly for making grooves on all types of wood and sometimes metals. A dado blade can be operated using a radial-arm saw, or the table saw to make grooves of any width of your choice. A dado blade comes in two designs, and they are stacked and wobble dado blades.

Stacked dado blades

A stack dado blade consists of a series of blades stacked to create a wider blade. The blades can achieve a precise cut with the help of spacers. On the outer layer of the blades, some chippers can be removed or added depending on your choice. The chippers are there mainly because they determine the length of your cut. Stacked dado blades are the top choice of most woodworkers because they are very versatile and have a high output.

Wobble dado blade

A wobble dado blade can be defined as a single blade with an offset rotation. Although it does shake a little bit while you are trying to create an “S” pattern on the width of the plate, the plate can be adjusted to your desired choice. The amount of lead on the blade can be set when you rotate the plates.

Dado blades have different sizes, so knowing what size to use is important in determining the outcome of your work. The normal size of the outer blades is usually 1/8 inches thick, and its diameter is 8 inches. It also has four chippers with different ranges, and with those ranges, the options for the widths sizes are abundant.

Dado blades can be used to make four different kinds of joints, and they include; dado and groove, rabbet, tongue and groove, and half lap.
