Having quality saw blades is crucial to being an effective woodworker. Of the different types of saw blades, dado blades are important in certain projects that require those special, precise cuts which other blades just can’t make. But which dado blades will work the best for you?

In this piece, we will look at the purpose of dado blades as well as five of best dado sets on the market.

What Are Dado Blades?


Before we get into the best dado sets out there, we need to define exactly what a dado blade is. Typically used with either a radial arm saw or a table saw, a dado blade is a kind of circular saw blade that is used to make either a groove or a dado.

Now, a groove is a cut made in a piece of word that runs parallel to the grain. Depending on the type of groove cut, grooves can be used in everything from cabinet making to roofing and flooring. A dado cut, on the other hand, runs across the grain and is essential in constructing bookcases, cabinets, chests, or any other case goods.

What to Consider Before Purchasing the Right Dado Blade Set for You


Before purchasing a dado blade set, you should conduct the appropriate amount of research, just like you would do before undergoing any sort of extensive woodworking project.

Of course, you will want to consider your budget. Dado blade sets may not be among the cheapest woodworking materials out there, but if you are willing to invest a decent amount of both time and money into that special project, a quality dado set can take you a long way. You will want to ask yourself the right questions first though.

How often do you anticipate taking on projects that necessitate dadoes or other similar cuts? Are the saw blades you are currently using not precise enough for a particular job? Does that next project require you to build shelving or paneling of any sort?

The answer to these questions could potentially help you to effectively determine the right dado blade set for you or if you need one at all.
