How to Choose the Best One?

There are some dado blades with features that might seem appealing at first, but they might not be suitable for you. Thus, it’s unwise to purchase without considering some key factors beforehand. These features will allow you to understand what type of dado blade you really need.

Type of Blade

The main factor to consider when buying a dado blade is its accuracy. There are different types of dado blades, each with their individual purpose. A wobble blade is usually a cheaper option but doesn’t offer high accuracy. They are suitable if you’re just a beginner.

However, a stack dado blade is more accurate. It enables you to cut the different sizes of grooves and apply a smooth finish. You will rarely need to apply repeated cuts to get the expected results. Stacked dado blades are usually expensive.

Compatibility

The dado blade you wish to buy should be corresponding to the type of saw you’re using. For example, a blade that’s compatible with a table saw might not fit in a radial arm saw. Most blades are compatible with all types of saws, but the standard speed of the blade may differ.

You need to check if the standard speed is compatible with your saw. On the other hand, some table saws don’t have a long enough arbor to fully support a dado blade set. Forcibly attaching the dado blade anyway will be a fool’s errand. You should rather try to cut one side of the dado first by aligning the fence.

Once you’re done, readjust the fence to finish cutting the dado.

Size

The size of a dado blade is not as important for its accuracy as you might think. Nevertheless, you should keep mind that a bigger dado blade will need more power to operate. 8-inch dado blades, like the ones mentioned above, can make almost all types of grooves.

A 6 inch blade would be more suitable for a low powered saw. 10 and 12-inch blades are ideally used for industrial purposes.
