Dado Blade Buyers Guide

Getting the right tools for your projects will save you added costs and a lot of frustrations. If you are a woodworker, you know just how much you need to be precise with your craft. In this article, we will look at the dado blade, which is an essential tool for a woodworker, and what you need to consider before getting one. 

What is a Dado Blade? 

A dado blade is a circular saw blade used with a radial saw arm or table saw to cut a dado or groove while working on wood. Before their advent, people used a specialty plane or chisel to produce rivets, but this was hectic and took a lot of time. 

Generally, there are two types of dado blades that you need to know before purchasing one. The first one is the stacked dado, made of two circular saw blades fixed on removable chippers. These chippers dictate the width of the grove. The stacked dado is not easy to set up and might be time-consuming. 

The second type is the wobble blade, a single blade system that you can efficiently operate. It is mainly a circular blade mounted on a hub. It is easier to set up and comes at a lower price. The only downside is that the wobble dado blade will not give you a clean groove like the stacked blade. 

Dado Blade Features

You need to have a few things in mind before settling for the best dado blade. These will dictate whether you get the right product or not.

Blade type

We have looked at the two options available (Stacked dado & wobble dado blade) in the market. Keep in mind that these types have their advantages and disadvantages. While one is cheap and easy to use, it does not give out cleaner and well-cut grooves. 

If you need more accuracy, you should settle on the stacked blade. It gives cleaner and more decent grooves. It is also highly versatile and can cut through several surfaces with ease. If you settle on the wobble dado blade, keep in mind that it is less accurate and will need a less powerful saw while working on your projects. The only advantage of the wobble blade is its cheapness and ease of usage.

While this may not be one of the most important factors, you need to pay close attention to your dado blade’s size. Fortunately, most of these blades measure 8 inches, which is enough for versatile usage. 

With the right-sized blade, you will easily create grooves for any project. However, keep in mind that you must have a power saw if you settle on a more significant edge. Therefore, if your saw cannot deliver, get the 6-inch blades. 

There are different sizes, including the ten- and twelve-inch blades, but they are most suited for industrial use. To be on the safe side, go for the eight-inch blade, and get a powerful saw. 


This is a significant factor that you must take into consideration. Before getting any of these blades, make sure they are compatible with either your table or radial blade saw. Luckily, most of these are universal and can, therefore, work with any saw. 

However, it would be best if you still ascertained this before buying one. A notable hack for compatibility is checking the teeth per inch (TPI) factor, which will help you know what your saw can work with to get the best blade. 

All these blades have a standard speed, meaning that you need a saw that matches up to the speed. You should check whether the arbor in your table is long enough to hold your dado set. 

Keep in mind that this comes naturally in the design. Therefore, do not try to improvise the arbor to fit your dado set, or you will be putting yourself and those around you in grave danger. A shorter arbor means less power. Such a blade cannot efficiently hold and operate a complete dado set. 

To save yourself from all these problems, get a compatible blade, and you will be good to go. While focusing on compatibility, you need to check out the diameter of the blade. This will determine the saw blade that will fit your dado blade. 

As a heads-up, 6-8 inch diameter blades are usually smaller and relatively lighter and do not need powerful saws. However, if you settle on the industrial blades, you must understand that they are generally heavier and require more power. Your saw blade should, therefore, be more powerful. 


Precision is of the essence when cutting through wood or related surfaces. Therefore, you should strive to have aligned and smooth edges that will easily fit other workpieces. You cannot achieve this if you do not have the right dado blade. 

When buying a dado blade, make sure that it will not give you uneven edges that make your results look unprofessional. 


The durability of your dado blade will dictate how long you will get to use it. It would be best not to part with tens or even hundreds of dollars on an item that will not last any longer. When shopping, make sure that you pay attention to the material used in making the blade. 

If you want to be safe, get a dado blade set made of premium quality materials such as carbide if you need to save costs. Such blades will serve you longer than you can expect.
