Buyer’s Guide

You can check table saw dado blade review articles online, but unless you know what to look for, you might still end up with the wrong blade. Most dado blade reviews offer you a list of products to choose from. To choose the best blade amongst those on the market. Dado blades are powerful tools to have in your collection of woodworking tools. Read on to learn more about dado blades.

Types to Choose From

There are two main types of dado sets:

Stacked Dado Set

Stacked dado blades are loved for their versatility. They have two outside blades, chippers and shims, which enhance the precision of cuts. The width you get with these blades is dependent on the number of chippers used between the outside blades. Most sets come with between 4 and 6 chippers. These units are precise and long lasting. Most of them are resharpenable, and they can be used on a wide range of materials. However, these sets are relatively expensive and challenging to set up.

Wobble Dado Blade

Wobble blades are simple and act as a single blade system. Instead of stacking, the blades use a different method to make grooves. The functioning of this blade requires that you install a single wobble blade with a hub which you use to adjust angles. The angles cause the blade to spin in a wobbly manner instead of spinning accurately like stacked blades. As this wobble blade spins at high speeds, it cuts through the material. Wobble blades are affordable and easy to set up. However, they are less accurate and often damage the saw.

Considerations when Buying a Dado Blade

You can choose a single blade from the best dado blade reviews above. A dado blade is a must-have tool in a workshop for serious woodworkers. With so many blades on the market, it is a challenge to choose the best. When shopping, consider: the following factors.


Blade Type 

This should be the first thing that you choose. Do you need a stacked blade set or a wobble blade? Stacked blades are preferred due to their accuracy, but they are relatively pricey.

Compatibility 

Dado blades are designed with a few variations, unlike other blade types. Granted, compatibility issues are minimal. However, you need to understand saw blade specifications to match the blade to the right saw. Teeth per inch, TPI, is one of the factors you need to consider when matching blades to saws. The blade material and hook angle also matter when matching blades. A high TPI is ideal for materials that chip easily while a low TPI comes in handy for high quality materials. Dado blades with a hook angle of 0 degrees are suitable for table saws while blades with -10 or -5 degrees are ideal for radial arm saws.

Power and Size 

The dado blade needs to be attached to a saw that will run it smoothly. These blades are either 6 or 8 inches, with the latter offering deeper cuts. Blades that are 8 inches will require powerful saws such as cabinet saws or contractor saws to operate them. 6-inch blades work perfectly on different saws irrespective of the power. Blades are rated for a given speed and they should be matched with saws that offer that speed.

Insert Plates

 Insert plates refer to the space that the blades protrude from. When you are searching for the best dado blade, this is an important factor as it determines the saw you mount it on. When planning to use the blade on a table saw, a customized insert plate comes in handy.

Common Joints

There are a variety of joints you can make with a dado blade. Considering the joints that a dado blade makes can help you in choosing the best dado stacks. Some joints include:

  • Dado Joint: This is the most common and the simplest joint to make. It is a simple trench made either perpendicular or across the grain of the wood. When viewed as a cross section, the joint has three sides.
  • Finger Joint: Also referred to as a comb joint, this joint involves cutting corresponding rectangular slots on two different pieces of wood and then joining them with wood glue. This is one of the strongest joints in woodworking.
  • Tenon: Tenons are used when making the popular mortise and tenon joints. It is a small rail formed at the end of a piece of wood to be inserted into a square or rectangular opening that has been drilled out on another piece of wood. Tenons should be made to fit perfectly on the mortise.
  • Rabbet: A rabbet is a groove made into the end of a piece of wood. When viewed from the side, it appears to be two-sided. This rabbet opens into the edge of the surface.

Conclusion

Your needs will determine the blade you choose. Most blades come in handy for hobbyists as well as professionals. The saw you have, whether a table saw or radial arm saw, will also be crucial in the blade you choose. Fortunately, these blades cover different budgets, allowing you to make your choice with ease.
