Whether you are a professional furniture maker or a beginner, there are tools to help you out. A dado blade is a tool used by woodworkers to saw and cut wood. A set of dado blades will help you shorten the time to complete the job and consume less effort. However, do you really understand it as well as how to choose a good dado blade? If not then this article is all you are looking for. Here, we will suggest a few things to keep in mind when choosing a dado blade. Do not skip this article.

I. Types of Dado Blade

A dado cutter is the first choice for cutting joints. It helps to improve working efficiency for projects. You can easily order a dado blade kit at any hardware store or website. However, it can be difficult to be sure that what you buy will be right for your project. Therefore, to avoid causing a waste of money, you should consult the information carefully before opening your wallet. The first and foremost thing when choosing a dado blade is the type. The dado blade is usually divided into two main categories, each with its own pros and cons:

1. Stacked Dado Set

  • Used by most woodworkers for its versatility
  • Consists of two outer blades, 4 to 6 hash knives.
  • Cut width can be adjusted based on the number of hashes.
  • High precision. The smart design increases cutting accuracy and perfect groove.
  • High strength. Not as easily corroded as wobbly blades.
  • Long service life. No need to re-sharpen many times. No need to replace it as often.

However, the stacked dado set also has the disadvantage of being quite expensive and difficult to set up. Despite its many benefits, the inclusion of multiple blades is the reason it sets it apart from the others. In addition, while it can increase efficiency, speed, and accuracy when working, it is quite difficult to install, especially for those who do not have much experience.

2. Wobble Dado Blade

  • Consists of one blade instead of multiple stacked blades like the Stacked Dado Set.
  • It uses a different technique for grooving wood surfaces.
  • Affordable due to including only one blade. Diverse brands.
  • Installation is quick and easy.
  • Suitable for professional and amateur furniture makers.

However, this type of dado blade has lower accuracy. It is difficult to achieve a good square groove and a flat bottom. In addition, their design also causes a lot of vibrations, causing the screws to loosen, which eventually leads to damage to the saw.

II. Guide to Buying the Dado Blade Set

A set of dado blades is an indispensable tool for every woodworker. Most professional craftsmen know how to choose a good dado blade set. However, for those who are just starting out, this is not an easy thing. Therefore, here are a few pointers for you.

1. Blade type

As mentioned above, the dado blade consists of 2 main types: Wobble Dado Blade and Stacked Dado Set. Each type has its own design to suit each certain project. Therefore, the first thing to do is to determine the right dado blade type you need.

Stacked dado sets are often recommended by many woodworkers because they are more precise, the joints have the perfect fit. However, if your budget is not large, the Wobble dado blade is also a good choice.

2. Compatibility

Dado blades do not have as many variations as most other saw blades. Therefore, the deviation between the instruments will be less. However, there are few but not impossible mistakes. It is essential that you choose the dado blades with the correct specifications for the saw.

Specifications: The dado blades usually have 0-degree angles to suit table saws. However, some other saw blades have hook angles from -12 degrees and -5 degrees.

Diameter and capacity: Most dado blades will be 6 or 8 inches in diameter. The 8-inch blade gives deeper cuts, so it is suitable for larger power saws. The 6-inch dado blade set is suitable for contractor saws, cabinet saws, hand saws, and table saws.

3. Materials

Besides the above factors, the material is also a factor that cannot be ignored. The materials used to make the dado blade determine its lifespan. Therefore, to ensure work efficiency, your dado blade needs to be made from durable materials with good rust resistance. In addition, they are also subject to impact, extreme weather, etc. Using poor quality dado blades will interrupt your project, even causing dangerous accidents. Typically, dado blades made of aluminum or alloy steel are more commonly used.

4. Price

As shoppers, we certainly like to buy cheap products. However, the money you spend will be proportional to the quality of the product. The good dado blades often come from well-known brands with high prices; but instead, you will have more efficient and safe experiences. And you also won’t need to worry about regular maintenance or replacement of the dado blade. On the other hand, if your budget doesn’t allow it, consider cheap products before you buy them.

Final Word

A dado blade is a useful tool, but not all types are of great use in your project. That is the reason why you need a better dado blade rather than a good dado blade. Hope the above guidelines will help you find a product you like the best. In addition, you can also consult more information from the salesperson or other customers to increase the accuracy of your decision. Thanks for reading.

  • DIY tasks and small workshops: You will need a machine with a suction power of 12-19 kPa, capacity from 15 to 20 liters. It would be better if you choose a product with high strength such as a plastic barrel model or a stainless steel tank.

The power outlet can also be seen as an advantage if you are using it with another tool.
  • Worksites: This site requires dust extractor vacuums that are powerful, fast, and efficient at work. Machines with capacities from 1,600 to 1,800 W; suction capacity from 19 to 25 kPa, stainless steel tank, tube about 8 to 11 meters long will be the ideal choice for you.

2. Features to consider:

Just like any other tool, before buying a dust extractor vacuum, you should consider the main features of each product. Here are a few features you should be interested in:

Power consumption (unit: Watts): is the energy consumption of the machine. A large vacuum cleaner usually consumes a lot of power. This makes your electricity bill thicker. Therefore, choose machines with the right capacity for the space you use.

Air flow per minute (unit: L / min): is understood as the volume of air that the machine will suck in. The larger the volume, the shorter your working time will be.

Vacuum pressure (unit: kPa – kilo-Pascals): The higher the suction power, the higher the vacuum pressure will be. It is better if you choose vacuum cleaners with a large surface area, high filter quality to clean the air more easily.

The size of the filter (unit: liter): If you often have to vacuum or use it for large projects, choose machines with large capacity. Small machines limit your working speed.

Weight (unit: kg): A machine too heavy is definitely something no one wants if you have to carry it with you. Most of the people using the vacuum cleaner are women, so compact, lightweight machines are a perfect choice.

Noise level (unit: dB): To comfortably use the vacuum cleaner anywhere, whether at home or in the workshop, you should check if it is making too much noise. In addition, if you are sensitive to noise, wear ear protection every time you use it.

Length of hoses and power cord: For spaces with great travel range, make sure your hoses are long enough to reach it.

The battery voltage and amperage should also be considered. The capacity and time of use of the machine depend on this factor. It would be inconvenient if the machine automatically disconnects when in use, right?

3. Accessories included

A conventional vacuum cleaner is generally enough to meet your cleaning needs. However, to perform many other tasks, you also need to prepare a few other accessories included, such as: Brush heads (rectangular or triangular), flat nozzles, wet and dry nozzles, extension wands, variable-length hoses, and accessory holder.

However, more recent modern vacuums will come with additional accessories to fulfill specific purposes.


The choice of a dust extractor vacuum depends on ensuring compatibility between your cleaning specifications and needs.
