I. Wobble blades

Dado Wobble blades

As the name suggests, wobble blades cut by wobbling back and forth. They only have one circular blade. Wobble blades often lack precision and leave uneven cuts, making them not a right choice.

Further, they have high vibration levels which may damage the saw. However, they are a cheaper option.

II. Stacked blades

Dado Stacked bladesOn the other hand, stacked blades have outer blades that are bundled together to give the cuts a large width. The often have 18 to 40 teeth whose key role is to give smooth edges. Stacked blades give precise cuts and are safer than the wobble ones.

They also have chipper blades in between them. The chipper blades have 2 to 4 teeth whose primary role is to remove waste from the middle of the dado blade’s groove.

They are the best choice, and all the units we have reviewed here are stacked dado blades.

Things to Consider – Before Buying a Best Stacking Dado Blade for the Money

A good Dado blade set is crucial in woodwork tasks. If you have one or are looking to buy one, there are some key things you need to know about the most ideal dado set for your wooding needs.

How to Choose an Ideal Set

There are vital guiding factors that are crucial in helping you make a good decision. Here are the factors we considered when creating the above list of the 7 best dado blade set reviews.

I. Reviews

Reviews from a product’s consumers and users help validate the effectiveness and authenticity of the product. They give you an insight into the performance of the product without you having to buy it. Pay attention to existing product reviews on independent websites. The above-reviewed dado blade sets stood out for having many positive reviews.

II. Price

Cheap is relative, and so is expensive. However, there’s a baseline of what is affordable to a large number of people. Have a budget and choose a pocket-friendly price as per your needs.

Key Features to Look for

I. Blade Size

A large number of dado blades come in either 6″ or 8″. The 6″ are not very versatile, but they use less power, making them ideal for use with low-powered saws. On the other hand, 8″ blades are more prominent and make deeper cut making them more versatile. However, they are highly powered.

II. Tooth Density

Different dado blades have a different tooth density (TPI), as we have already seen. Either number of teeth has advantages and disadvantages. For instance, a dado blade with a higher number of teeth is likely to give more precise cuts, is more durable, and doesn’t require regular sharpening. However, the quality of teeth supersedes the number.

III. Hook Angle

The best hook angle depends on the tool with which you will be using the blade. 0-degree hooks are best for table saws while negatively angled hooks (ideally -10 degrees to – 5 degrees) are best for radial arm ones.

IV. Blade Material

The inner part of a blade doesn’t require strengthening because it is the teeth that are involved in cutting. It is for this reason that most blades are steel on the inside. The teeth are made of superior carbide to give them extra strengthening. While some dado blade sets use stainless steel or C-4 carbide, others use the high-quality titanium cobalt carbide, which is more durable and holds an edge much better.

Unless you are into professional high-intensity woodworks, C-4 carbide is good enough.

V. Compatibility

Take the arbor size into consideration. Arbor refers to the stem into which the dado blades slide. 5/8″ is the industry standard and all the sets we have reviewed here are of this size. The chances of non-compatibility are minimal; however, before buying the dado blade, check for compatibility to avoid wasting time and money.

Another compatibility factor is the saw’s maximum power capacity and speed. Before buying the dado blade set, check your saw to ensure that it meets the power and speed requirements of your preferred dado blade set.

First, read and understand the manual instructions on effective set-up and usage of the blades.

In addition, you should not use stacked or wobble dado blades with circular saws because they are only designed for use with a compatible table or radial arm saw.

Always wear protective clothing, goggles, and gloves to prevent sawdust from entering your eyes. Feather boards should also be used to securely hold the wood in place to prevent backward friction and sliding that is one of the main causes of injuries when using dado blades.
