Also, the blades and chippers that come with this set have Freud's unique design with anti-kickback features that boost safety in all working environments, which is crucial when working with these tools.

Speaking of design, it's essential to mention the technology behind the carbide grain mix of this tool. In most cases, the larger the carbide grain, the edge will wear faster.

If you need something to get the job done now and efficiently, search no further than the STCKD Dado Blade Set.

Naturally, dado blades come in sets of two, and, in this case, you’ll receive 8 x 12-inch blades with 12 teeth each that are resharpenable using the standard sharpening gear, automatic or manual.

Moreover, the overall accuracy is increased thanks to the ⅝-inch laser cut.

It cuts clear angles, but you can use these blades to rip wood across the grain, and you’ll still get efficient results.

The blades are durable thanks to the micro-carbide titanium build that works wonders in terms of overall durability.

Also, it’s not prone to rust, and you can even forget to clean it from time to time, and you won’t see any damage to them. Speaking of this, we mustn’t forget to add some information about the perma-shield coating that protects the blades from heat and gumming.

You can’t ask for much when it comes to dado blades - the bottom line is that they’re sharp, durable, and deliver with each cut. On the other hand, these blades might be a bit overpriced, which is where we’ll deduct a point.

If testing out new products tires you and you just want to get something that’ll last you for years, it’s time to test out the Amana Tool Carbide-Tipped Dado Blades.

This set of blades is as straightforward as it gets - you get the standard two blades and four chippers.

The blades are made of premium materials, and they have an alternate top bevel (ATB) on every sixth tooth for angled cuts.

The hook angle is set to 15 degrees, and each blade has 24 teeth, which is quite handy when working with hardwood.

Moreover, the outside blade has hollow-ground plates, which enable clear cuts and smooth finishes.

These blades are industrial-quality, and they’re made from carbide-tipped alloys that protect the blades at high temperatures that stem from frequent friction that occurs when you’re cutting without pauses.

You’ll be able to expand the width thanks to the chippers; you’ll get anywhere between ¼ to 13/16 in., but you can purchase separate chippers for these blades to expand the width up to 1 inch.

The thing we don’t like is that it’s not a standard ⅝-inch arbor, which might pose some problems when sliding them on the saw.

On the other hand, the resulting project will be smooth, so it’s worth the hassle.

  • Industrial-grade quality
  • Premium pick
  • 15-degree hook angle
  • Carbide-tipped
  • A bit smaller than ⅝ arbor

The Benefits of a Dado Blade

best dado blade set for the money

Ever since its inception, the dado blade has always been one of the best possible choices for enriching your tool collection.

  • Usually, in the industry, tools are rated by their versatility. If you take that into consideration, there are few tools on the market that can match the myriad of things the dado blade can accomplish.
  • If you are in need of dadoes and grooves in your work, you won’t have to hassle with regular circular saws.
  • The double cut that the dado blade can achieve is unmatched and will leave you with clean and natural slots.
  • You can also experiment and also make tenons and rabbets with this amazing tool.
  • Even a box joint can be in consideration, as the dado blade was tailor-made for versatile performances.
  • The best benefit of the dado blade is perhaps the saving of your money. As the blade can be connected with just about any radial arm saw or table saw, you will pretty much be just purchasing an add-on.

Furthermore, the bottom line is that you are making a small investment that yields incredible results. If you are willing to test this theory for yourself, don’t hesitate to head to your local appliance store.

Many have active testing areas for you to assess the quality of the product.

What to Look for When Buying a Dado Blade?

1. Quality and Price

best dado blade set reviews

A common mistake by many woodworkers is sacrificing quality just to save money. This is somewhat the fault of the market.

Since it’s so big, prices to pay can vary greatly and cause confusion.

Just because different manufacturers compete with each other, doesn’t mean you have to be swindled. A good, hard look at the product you’re buying will be the solution to just about any dilemma.

All in all, everything is pretty clear and in the majority of cases – you indeed get what you pay for.

2. Respected Brand

A brand means much in the dado blade world.

Reputation is also significant, so respected brands always invest in improving their quality and pleasing their loyal customers.

Since so many people buy from them, money is not a problem and they always want to stay ahead of the pack. So, for starters, a respected brand is what you should aim for.

A less known brand from, let’s say, from the Asian market, will often be made from a lower quality material.

This may put both you and your work in danger. You don’t want injuries as much as you don’t want a dado bottom that’s not precise.

Precision is the next important thing on the checklist.

3. Adaptability to Different Blades

The final thing you should be looking out for is the adaptability to different blades.

Many manufacturers cite this as one of the main goals – to have their dado blades connect to every saw.

Keep in mind that there are still brands who produce dado blades only for their saw, or for a limited number of models.

Ask around before purchasing and you should be pretty much fine.

How to Use a Dado Blade, Anyway?

Using dado blades of any type or brand is pretty simple.

  • The only thing that can vary across models is the width of the cut and the way to set it up. When setting up the saws on the arbor, you should take a look at the distance between them and measure the width of the gap thoroughly.
  • Also, when adding the blades on the arbor and before use – check the dado throat plate.
  • Never remove that part of a blade, as that can bring many risks to the table. Risks are unwanted in the woodworking business. No matter how majestic your piece may turn out to be, it’s all in vain if you are putting yourself in danger.
  • Check if there are spacers (for increasing width) included with the set and apply them carefully.
  • The only other thing you need to take care of is the speed of work. Rememberyou’re not in a hurry! Slow and precise cuts are the way to go. That way, you can stop at any time and correctly assess the state of the cut and how do you want to continue.

Everything else is pretty much self-evident and included in the manuals. Use protection and good luck with the cuts!


Does my cutting depend on the type of wood and if so, how?

​Yes, of course. Dado blades are made out of industrial grade, stainless steel or titanium. Therefore, no material is a problem for them to cut.

You only need to assess the line of the tree fibers and check how fast the saw goes. When you know all that, just adjust the speed accordingly.

Are warranties regular in the dado blade world?

Certainly. Most manufacturers include 5+ year warranties or life warranties. The longer the warranty, the more respected the brand.

The length of it shows how much faith the company puts in their blades.

How to deal with mistakes?

the best dado blade set

Like with any profession, crooker cuts and overly deep incisions are a normal thing and they shouldn’t be treated overly dramatic. Just turn the saw off and assess the situation.

Take a deep breath and check the severity and devise a plan on how to continue. In some cases, throwing away the entire piece may be required.

When not, just increase the depth or the width and everything will be okay!

What about protection equipment?

Like with any sharp object – attention is of the utmost importance! Industrial grade gloves are the first things you should think of purchasing.

Remember – your fingers are more important than the piece! You can make a new piece of work, but not new fingers.

Also, think of getting protective goggles and a mask.

Wood can be cut to very small, barely visible pieces and therefore can sometimes get stuck in your eyes and in your respiratory system.

Years of exposure sawdust can cause severe lung problems or even damaged eyesight. Don’t even think about stepping into the workshop without the needed equipment!

What about the manuals?

best dado blade set for sawstop

Whether you’re buying in your local store or ordering over Amazon, there should always be a clearly signified table of contents.

It’s common courtesy that a manual is included with your dado blades, but here are instances where it isn’t.

Don’t even consider those brands! Every manufacturer should aim their products at both novices and advanced woodworkers.

A brand that doesn’t respect this is most likely not to respect other regulations.
