3. The Mibro Group 416381 8” Dado Blade Set

If you are on a budget and desire to make large grooves, the Mibro Group 416381 8″ Dado Blade Set will make a good choice for you. 

The dado blades are high-quality and are ideal to cut pavers perfectly. The teeth are carbide-made to maximize durability and guarantee fine cutting performance. 

I was impressed with the cutting speed. The blade cuts at 5000 RPM and does so with finesse[1]. However, the set only includes two 8″ cutting blades that are somewhat limited to the number of projects it can handle. 

There is also anti-kickback to prevent work injuries when the material moves too rapidly.

4. Dewalt DW7670 Dado Blade Set 8-Inch

Dewalt is another company you can trust as far as making woodworking tools is concerned. The Dewalt DW7670 Dado Blade Set 8-Inch is among the best dado blades for cutting, thanks to its features. 

When I use this blade, I can’t help but appreciate its 24 carbide teeth, allowing me to cut rapidly at speeds of up to 7000 RPM. I’ve sliced through hardwood with it, and the results? Seamlessly smooth finishes every time.

What I particularly like about this blade set is the laser plates, which, in my experience, ensure that each cut is spot-on. And even after putting them through their paces for quite some time, they’ve remained razor-sharp. Plus, the included storage case is a godsend, helping me keep my blades in pristine condition and ensuring they deliver top-notch performance time after time.

Dado Blade for Circular Saws Buyer's Guide

Dado Blade Type and Size

In my quest for the best dado blades for circular saws, I’ve come across two main types – stacked and wobble blades. From my experience, stacked blades are fascinating; they come as a set with multiple blades that you can fix side by side, allowing you to adjust the cutting width as needed.

Wobble is a single blade and is generally not the best for beginners due to its staggering cutting motion. However, it’s more affordable than stacked dado blades.

TPI

Teeth Per Inch (TPI) refers to the number of teeth on a blade per one inch of its length. Different blades come with varying TPIs, and each serves a specific purpose. Blades with fewer teeth are designed to cut through lumber quickly, while those with more teeth provide a smoother and more precise finish.

Material Quality

In my experience, the longevity of a blade is really determined by the quality of its material. The dado blades that have consistently lasted the longest in my workshop are those made of top-notch materials like carbide.

My Top Pick For a Dado Blade for Circular Saws:
Freud SD508
