The Best Dado Blade Set for Table Saws
A set (or “stack”) of dado blades is used on a table saw to cut dadoes, grooves, and rabbet joints. All three joints are essentially the same, except for where they are cut on the board:
- Dado: Cut across the grain, to hold shelves
- Groove: Cut with the grain, to hold tongues or cabinet backs
- Rabbet: Cut on the end or edge of a board
With a series of blades, chippers, and shims the desired width of the dado, groove, or rabbet can be dialed in accurately with a dado blade set for table saws.
When choosing a set of dado blades for table saw, the first thing to remember is that you need to buy a dado blade set that is one size smaller than your normal table saw blade. If your table saw uses a 10 inch table saw blade (the most common size), then you would purchase an 8-inch dado stack. Also look for a dado set that has a good number of shims, to allow for fine adjustment of dado size. Most dado blade sets on the market have carbide tips, so the main difference would be manufacturing quality. So rely on customer reviews to help you weed through differences in quality.
In my opinion, here are some of the best 8-inch dado blade sets on the market…click on the name to compare prices & reviews:
If you will be using the dado stack on a SawStop table saw, then you will need to buy this brake cartridge (pictured above) for use with your 8-inch dado stack. Otherwise your SawStop won’t even turn on when a dado stack is added. The SawStop computer is pretty smart.
And when using a dado blade set, you’ll also need to buy or make a zero clearance table saw insert to dedicate to dado blade use. I’ll discuss that more below.
