We tested 15 sets for smoothness of cuts
Synopsis: Steve Latta uses dado heads to cut tenons, dadoes, grooves, and rabbets in a variety of materials. Because the cost of a good set can run more than $200, most woodworkers have only one set, so it’s important to find one that works well and fits your budget. Latta tested 15 sets of 8-in stacked dado sets with carbide teeth. He and his students cut and compared more than 500 samples of dadoes cut cross-grain in red-oak veneer-core plywood and particleboard-core melamine. In addition to comparing dado brands, he also offers tips on using dado blades safely.
