Before we introduce each of these dado blades, we will make a brief detour first. Specifically, we want to emphasise the purpose of dado blades. Moreover, we also need to elaborate the important factors that indicate the quality of this tool. In this way, you can get the right dado blade that would accommodate your needs and intended applications.
What are Dado Blades?
For those who are still new in the world of power tools, dado blades (dado set for some) are a group of cutting tools that have been stacked to make broad cuts. You can easily compare a dado blade to the blades that you can see on circular saws. However, this cutter is typically standard on radial arm saws and table saws. In general applications, the usual width of a dado blade ranges from 1/8 inch to 3/4 inch.
As we mentioned earlier, you can utilise this type of blade for making joint cuts. You can use them on your renovation and construction projects. However, they work best on woodworking tasks.
Dado Blade Variants
The first thing that you should know about dado blades is its main variations. Specifically, there are two types of dado blades today: the stacked and wobble.
Stacked Dado Blade
If you are a serious woodworker, we recommend that you should go with a stacked dado set. Aside from being powerful, the stacked set offers guaranteed versatility. The anatomy of this variant usually features two sets of exterior blades and interior chippers. The combination of these components will allow you make fine adjustments to the width of your cut.
However, you should know that the width is still dependent on the count of chippers that the stacked dado set has. In the market today, you can see models that offer two to six chippers. Of course, the higher the number, the wider the cut can be made.
Stacked dado blades provide extreme precision in joint cutting. Its large number of cutters will allow you to make the perfect cut and groove without missing a hit. They also offer durability, thanks to the plethora of teeth that the blade has. They can cut without wearing the parts down, making them more long-lasting than wobble blades. On the other hand, you should know that stacked sets are expensive.
Wobble Dado Blade
On the other hand, a wobble dado blade is the direct opposite of the stacked set. Specifically, it only uses one steel in its setup. Therefore, you are required to make various cutting technique to create grooves and joints. After all, you cannot rely on stacking anymore. Of course, this would compel you to install a hub with the wobble blade. In this way, you can be able to adjust the cutting angle of the blades.
As its name suggests, wobble blades tend to shake. It causes the inaccuracy in the cuts it makes. But since it is only a single blade, the spinning motion that it has is rapid. It can easily cut wood materials for any joinery projects.
We can also say that wobble dado blades are cheap. We compared their prices with stacked dado blades and saw the glaring difference. In fact, some wobble dado blades are half cheaper compared to their stacked counterparts. Another good feat of this type of dado blade is its user-friendliness. Specifically, you can quickly set this one up even with minimal guidance.
Choosing a Dado Blade
You cannot just settle with low-quality dado blades. Otherwise, you won't have an excellent time working on your projects. A professional woodworker would never pick a dado blade that cannot live up to their standards. Even amateurs should have that conviction, too.
One of the crucial factors in choosing a dado blade is compatibility. Regardless of how good a unit is, if it cannot fit your setup, it is still useless. Fortunately, you can quickly determine the compatibility of a blade through the following:
You need to look for the intricate details that revolve around an individual dado blade. For example, terms like "Teeth Per Inch" (TPI) will give you an idea of the intended application of the cutter. Specifically, those units that have a high number of TPI is an excellent choice for cutting hard materials. They can cut fast and elegantly.
A dado blade cannot perform well if it doesn't have the structural rigidity and durability that it needs. You need to guarantee that the blade that you are going to choose has optimal quality. Most of the dado blades on the market either come on 6 inches or 8 inches in diameter. Usually, 8-inch dado blades are perfect for making deep cuts. They are ideal for cabinet saws because they can sustain its power. Meanwhile, 6-inch blades are for portable and bench saws.
Specifically, add plates the region in where the blade extends. It plays a vital role in the selection process of dado blades. For example, if you want to use the dado blade on your table saw, the former should come with a modified insert plate. You can either choose a pre-cut insert plate or a zero clearance insert plate in this matter.
