Dado Blade for Circular Saws Buyer's Guide

Dado Blade Type and Size

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 is the number of teeth per one inch of the blade. Blades come with a different TPI. Blades with fewer tooth counts cut faster on lumber, while those with more teeth leave a smooth result. 

Material Quality

The material quality determines the blade’s longevity. Dado blades that stand the test of time are of high-quality materials, such as carbide.
