Infinity Cutting Tools - Dadonator Dado HeadThe Dadonator from Infinity Cutting Tools cuts flat-bottom dadoes from 1/4-in. to 29/32-in. wide.
Most woodworkers buy only one set of dado heads, so it’s important to find one that works well at the right price. Author Steve Latta tested 15 sets of 8-in. stacked dado sets with carbide teeth. He and his students compared more than 500 samples of dadoes cut cross-grain in red-oak veneer-core plywood and in particleboard-core melamine. They evaluated tearout, how deeply the outside blades cut a visible scribe, and whether the bottom of the cut was flat and smooth. Infinity’s Dadonator standard 8-in. dado head produced excellent cuts in both plywood and melamine, with no visible scoring marks and smooth bottom cuts. Author’s choice for Best Value.
