Advantages Of Having A Dado Blade At Hand

There are certain advantages that these blades bring into the table that the other tools are not capable of. These are:

Ease of Use

Unlike the other power tools that are used for cutting woods, dado blades feature a design that will let you quickly make joint cuts, rabbets, grooves, and different types of slots on your wooden project.

Set up Process

They are also reasonably easy to use, and setting them up is no hassle at all. Most of the sets will ship with some sort of included guideline in the package, but even if they do not, you can easily figure stuff out by yourself.

Also, they will fit in most of the saw tables. Even if you do not have a particular table for installing them, you can construct a makeshift one by using the wood that is lying around you.


Besides that, they offer an incomparable amount of accuracy, and you will be able to get precise cuts that would be quite hard to get with other tools. You will have not even have to put that much effort in lining up the slots of your wood piece with them.


As most of the sets come with high-quality construction, they last for a longer amount of time. The edges remain sharp for a long time as well.

What To Look For Before Buying

Not all the units that you will find in the market will give you the optimal performance. That is why you have to scrutinize. And, to do that, you have to keep a couple of things in your mind before heading out. These are:



Before you start searching for a dado blade, you should know their types. There are usually two of them. One is the stacked ones, and the other one is the wobble type.

The stacked ones are the ones that most of the woodworkers prefer because of how precise and comparatively easy to maneuver they are. They are called stacked because they have one blade stacked right next to the other one, and in between them, there is a “chipper” blade.

Depending on the manufacturer, the units will ship with 18 to 40 teeth. They are comparatively precise than the other one.

On the other hand, the wobble styled ones have only one circular blade. These blades are generally mounted at an angle that allows them to wobble forward and backward.

This wobbling is where the name comes from, and because of this wobbling, they tend to output inaccurate cuts. That is why this is usually not picked up for professional wood cutting projects.

Teeth Count

The number of teeth that a blade features will have an impact on the overall cut on your wood. With higher density teeth, you will be able to get much finer and smoother cuts.

Also, the number of teeth that a disc might have depends on the overall size of the blade. The larger the size, the more teeth it will have.

On that note, the market has units that are between six inches and eight inches. Among them, the most popular one is the eight-inch one because it can give comparatively deeper grooves than the other one.


The overall sharpness is a crucial factor, as well. You would not want to get something that will not be able to go through hardwoods, would you? That is why you should factor in the sharpness of the blades as well. The sharper they are, the easier it is you to cut through your wood piece.

The Quality of Cuts

Many of the available units usually give a jagged cut. In that case, what you have to look for is the hook angles. If they are negatively angled, they will be virtually splinter-free and will give you a smooth and flat cut on your wooden project.


As a tool, you would want the unit that you are investing your valuable money to last. In that case, if you get something that chips after just a few uses will be an expensive mistake. So, you should put the durability of the units into your consideration too.

In the case of durability, it all depends on the overall construction material. Even though most of the units are featuring a high-quality carbide construction, some might not. In that regard, look for the ones that state C-4 carbide or TiCo carbide. Some are of stainless steel, but they tend to lose the edge retention pretty fast.


Compatibility is another crucial factor that you should consider before you make a purchase. You should know the size of the arbor that your saw table feature and get a unit accordingly. It will be a big hassle to return the set that you just purchased only to know that it will not fit in the arbor that you have.

Cut Widths

Even though most of the blades in the market nowadays can cut different sized cuts, many of them also sport an on-the-go adjustment knob. But, few might not be able to get the cut width that you might specifically require.

In that case, you have to consider whether the unit that you are getting can cut the width that you are looking for or not. It should be stated on the packaging.


If you are a veteran, you can skip this part. But if you are relatively new to the overall concept of dado blades and just got yourself a new saw table for cutting precise grooves, then you should consider this part.

Manuals state the installation process and about all the adjustments that the unit is capable of, and thus it gets a little bit easier for the beginners.

Diameter and Power

Being a woodworker, it is important to make sure that the dado blade matches to a saw to run it optimally. Most dado blades come with a diameter of 6 or 8 inches.

The larger 8-inch blade is ideal for deeper cuts. It requires a saw like a cabinet saw due to its power and some types of or contractor saws to operate it.

On the other hand, a 6-inch dado set can work on contractor saws, cabinet saws and also with the portable and bench saws.

Insert Plates

An insert plate is where the blades protrude from. It is an important factor to consider in the search of the best dado blade set. For a table saw, it would be necessary to install a customized insert plate to use the blade.

For this, choose between a pre-cut dado insert plate and a zero clearance one which does not have a pre-cut slot for the blade and so you have to make it with your dado blade.

Consider these points before buying dado blades.

Frequently Asked Questions

Q: Which type of blade is the one for me?

Ans: Among both the variants, the one that most go for is the stacked one because they are easier to work with and output a precise and accurate cut. Keeping that in mind, if you are doing professional wood works, we recommend you to go with this one. Other than that, you can pick the wobbling one.

Q: In what type of saw should I attach my blades?

Ans: You should attach the dado blades in a table saw, or circular saw. The one saw that you should steer away from in case of these dado blades is the circular saw.

Q: What are the safety measures that I should keep in mind?

Ans: You should not use the blades by removing the throat plate, and you should always make sure that the arbor nut is tightly secured. Also, you should maintain a safe distance from the units while working.

Q: What is a Rabbet joint?

Ans: It is a groove that is usually cut at the edges of a wood piece. They are two-sided when viewed from a cross-section.

Q: Can the teeth of a dado blade chip off?

Ans: Yes, they can. If the blades are of low-quality materials and are not durable, they can chip off. Also, it can happen during shipping.

Why are dado blades illegal?

In many parts of the world dado blades are not illegal. … The main reasons are because to use them the blade guard and riving knife have to be removed. These are two safety features that are essential for the safe use of a table saw.

Are dado blades dangerous?

Yes, a dado blade is potentially hazardous. Heck, most woodworking tools (like these here) can be hazardous. It’s how you use the equipment that reduces the potential for injury. In regards to making a dado at the end of a piece, it would be better to use a sacrificial fence with the dado blade slightly buried.

Where are dado blades illegal?

As already mentioned dado blades are illegal on UK (EU) table saws because in order to use them the guard and riving knife have to be removed, and is therefore unsafe. This is not the case in the USA. Because of this, all UK or european table saws are deliberatley fitted with short arbors to prevent their use.

How deep can a 6 dado blade cut?

The radius of a 10″ blade is 5″ so if you have 3″ above the table so you need 2″ from the arbor before the business starts. A 6″ dado has a 3″ radius, so that puts you at roughly 1″ cut depth.

Can I make my own dado blade?

yes. A self made stack will cut grooves but the bottom is likely to be riddled with ridges. Stacked dado sets have bevel edges on the outside cutters, and flat teeth on the inside chippers that are all very closely matched to give low tearout at the exit of the cut, plus leave a nearly perfectly flat bottom….

Can all table saws use dado blades?

Many table saws accept dado blades with a maximum width of 13/16 inches. Dust port: Table saws produce a lot of sawdust, but table saws with cabinets keep dust fairly well-contained. On all types of table saws, look for a dust port if you want to connect to a dust collection system as you cut.

Can you tilt a dado blade?

You can certainly tilt your dado stack to the roof pitch and run the roof boards over it, but when you put them in place the sides of the dado will be ninety degrees to the roofs pitch, not plumb!

Can you Dado MDF?

Dados are too tight in MDF

Since MDF dulls blades fast, I prefer to cut them with a straight cutting carbide router bit instead of dado blades. The new Bosch 3/4 inch straight cutting carbide router bit leaves a dado that the 3/4 inch MDF cannot fit into — VERY close.

Can I put a dado blade on circular saw?

Dado joints are a simple way to join wood together, but they require a precision cut to be effective. If you don’t have dado blade or table saw, you can still cut dado joints using a circular saw and a couple jigs.

Why can’t you use a dado stack in Europe?

To European regulators dado sets are not considered safe. Part of this may be related to blade brakes. A dado set is heavy, and can spin off if the arbor stops too quickly.

Are dado blades legal in Australia?

They are certainly not illegal in Australia, nor is there any need to import one from the US. At least 2 companies, Northwood Tools and Carbatec, sell dado sets.

Q: What saw types can be used with a dado set?

Ans: Dado sets can be operated with either table saws or circular-arm saws. The type of dado blade you can use varies depending on the saw you have.

Home table or bench saws will work best with six-inch dado blades that are relatively lightweight. On the other hand, contractor saws will work with either six- or eight-inch dado blades as long as the chippers are lightweight.

Q: What kind of joints can be made with dado blades?

Ans: Dado blades are designed to cut grooves best known as dadoes or rabbet joints. These grooves help to fit the edge of one piece of wood into the groove for gluing or holding in place with pressure.
