Whether you are a full-time carpenter or an occasional DIY enthusiast, making sure that you have the best quality tools will not only save you time and money but will also give you the best results.

A cheap drill, for example, will result in insufficient torque and will be far more likely to blow up while a poor quality screwdriver will lead to threaded ends and the horrible task of having to drill out the embedded screw when you can’t unscrew it.

Finding the top dado blade on the market is no easy task unless you are happy to buy them all so you can compare them yourself. Since this is expensive, it is obviously something that most people don’t want to waste the money to do. That is why we have done the work for you and reviewed all the dado blades to find out which one is really the best.

What is a dado blade?

A dado blade is designed to be used with a saw bench that allows for wide cuts to be made in wood. A normal saw blade will slice wood but won’t cut out any area larger than the blade width.

In the past, woodworkers would cut two ‘channels’ in parallel into a piece of wood then use a chisel to hollow the center piece out. If you have ever done this, you will certainly know how time-consuming this process is, which is probably why you are now here looking for a dado blade.

How does a dado blade work?

It is a series of blades that are positioned together so that when they cut they create a channel or ‘dado’ in the wood. Two exterior blades make the wall cuts while in between these is a series of other blades or ‘chippers’ that carve out the internal channel. The design of these chippers varies quite a bit, but the overall function is the same, to remove the wood from the channel.

The drawback with this type of blade is that it will only create a cut that is the width between the two exterior blades, so should you wish for different widths, you will need to spend the time to adjust it. Typically, this means taking the blade apart and adding or removing inner chippers and shims.

For more information on how to cut the perfect dado, you can read this really helpful article.

What are the different types of blades available?

There are two main designs of blades available, the stacked dado blade and the wobble blade.

Stacked Dado Blade

This is by far the most popular type of blade used for cutting dadoes or rabbits. The reason for this is that the design offers a really good level of stability when cutting which obviously helps with the cut precision as well as helping with safety.
Most blades range from 1/8 inches up to ¾ inches and are fully adjustable for different sized cuts.

Wobbler Blade

Wobbler Blades

These types of blades that are otherwise known as adjustable dado’s use a different approach to create dadoes. They are a singular circular blade that can be set up to adjustable angles which then ‘wobbles’ as it cuts the wood. This wobble allows the blade to cut out dadoes as it cuts back and forth across the wood.

Stacked Dado vs. Wobbler Blades

Best Dado Cut – Winner - Stacked Dado

Ease of Use – Winner – Wobbler

Adjustability – Winner - Wobbler

Cut Spacing – Winner - Wobbler

Safety – Winner – Stacked Dado

So which one should I choose?

To decide on which blade type is best for you, you really need to consider if you are looking for the cleanest cut or for the most levels of adjustability. If the cleanest dado cut is most important then get the stacked blade whereas if it is adjustability, then buy the wobbler design. We have included below a quick recap of the pros and cons of the two different types of blades.

Stacked Dado Blade

  • Cleaner cut and dado
  • Multiple blades

  • More time consuming to set up and adjust
  • Cuts to exact standard cut measurements only

Wobbler Blade

  • Single blade
  • Easy to adjust

  • Needs to be run at a slower feed rate than with a stacked blade
  • Cuts dados in-between standard spacing

What to keep an eye out for when trying to buy the best blade.

There are 2 main things to focus on when buying any blade, design and quality. Though most of the better dado blades aren’t exactly cheap, you can expect them to last quite some time. This means with the more expensive designs you will definitely get your money’s worth as long as you take care of them and do your best to avoid old bits of wood that might have nails in them.

As far as design goes, it is worth doing your homework to make sure that there are no repeating flaws that continually rear their ugly heads. You can do this by reading plenty of customer feedback, which is available on all reputable online stores.

When it comes to quality, we recommend that you avoid cheaper brands that have dubious reputations. Made in China is not a hallmark of poor quality as in fact most products are currently made there. Even if you buy a reputable brand, it is likely that the blade has been made in China, meaning that in fact this is not really an issue.

Above all, we recommend that you do you research before you buy to ensure you are getting the top blade for your needs.
