Fact Checked By James A Weber | Post Updated On: June 26, 2021

Looking for the first dado blade set for your DIY table saw?? Or, planning to change the old ones? Whether working on wood is your hobby or whether it is your profession - every time you will have to cut grooves on your workpiece, you are going to have to be precise and accurate. Otherwise, the hollows are not going to line up in the finished product.

And that is where dado saw blade come into play!

All about Dado Blade Sets

A dado set or dado blade is a kind of circular saw blade, usually wielded with a table saw or radial arm saw. It is used to cut dadoes or grooves while carpenting.

There are two common kinds of dado sets - stacked dado set and wobble blade.

Stacked Dado Set

The stacked dado set is made up of two circular saw blades fixed on both sides of a set of removable chippers. As the dado sets spin, the two outer blades cut the dado sides and the chippers remove the waste material remaining in between and flatten the bottom of the dado.

The chippers are movable within the set as required to make a dado of the desired breadth. They can also be combined with spacers to finely vary the dado width. Thus, to change the dado width, you have to completely remove the stacked dado blade set from the arbor. After disassembling, chippers and/or spacers can be used to achieve the desired width of the dado set.

Wobble Blade

Wobble dado blades are also called adjustable dado, which consists of a circular blade mounted on an adjustable multi-piece hub.

The width of the dado cut adds up as the hook angle gets farther away from the radial normal(90°) towards the arbor. While it is possible to adjust the thickness of the cut when the saw is mounted on the arbor, accurate adjustment is yet difficult to achieve. This happens because tightening the arbor screw often changes the adjustment.

Wobble blades can only make a flat-bottomed dado at one width setting, which may be a drawback in certain woodworking operations.

Another flaw of a wobble dado blade over stacked dado is unpleasant vibrations. The magnitude of these vibrations varies with the blade's angular balance. The wider the wobble dado blade you cut, the stronger the vibrations will be.

The outer dado blades resembles and cuts like standard saw blades. The tooth count varies between the range of 18 to 40. The higher the tooth count, the cleaner and sharper the edge of the grooves cut.

● Inner Blades

Inner dado blades and shoppers compensate for the outer blades’ spaces where there is no tooth. The tooth count can be from 2 to 4, whereas the lower number means the chipper will cut more coarsely than the outer blades.

● Quality Assurance

A common mistake by the buyers is to consider the quality of the product for the price. They are not to be blamed, the market is so large that the manufacturers fight very closely with price options.

However, having a close look at the product and its features goes a long way to ensure that you get what you pay for.

Buying from a brand holds much importance in the dado blade world. A respectable brand will always take care of the regulations, customer satisfaction and entity compared to a local brand from Asian market. That's why we suggest going for professional brands from Germany or Italy.

You don't want to get injured nor a dado groove cut that is not detailed!

But many manufacturers cite this as one of the major points - to have their blades fit any saw. Ask around before making the purchase and you should be fine with a set’s adaptability to different brand saws.

FAQs About The Best Dado Stack

Frequently asked questions that we reviewers face the most are:

Are Dado Blades illegal?

Stacked Dado blades are marked illegal or banned in some countries like the European Union and the EU. Mostly when the country has a set of strict requirements to award a commercial tool a CE mark. It is because you have to remove the blade guard and driving knife while using the blades, which are two basic safety features for any table saw.

How important are manuals?

As previously said, manuals are very essential for power tools whether or not you are a professional. A brand that includes a user's guide or booklet in the package, reflects that they care about all norms of their buyers, from beginners to commercial.

We suggest Oshlun to be the best brand in that sense.

What protection equipment I may need?

Working with a commercial tool?

Attention is a must! Make sure you aren't talking to someone or looking away while making the cuts. Secondly, wear protective goggles to avoid bits and pieces going into your eyes. Wear a mask to be safe from wood dust, especially if you are prone to breathing problems.
