This 8-in.-dia. dado-blade set from Bosch recently came on the market. Its blades have 24 teeth and can cut dadoes up to 13/16 in. wide. As a basis for comparison to other dado blades, I followed the testing procedure used by Steve Latta when he evaluated 15 dado sets in FWW #176. I tested each blade by cutting melamine and veneer plywood. The plywood was cut across the grain of the face veneer. I made up samples of each material, 3/4 in. thick by 12 in. wide by 16 in. long. I then set up the dado set to cut a 3/4-in.-wide by 1/4-in.-deep dado with each pass, making 22 passes on each sample of material for a total of 44 cuts with each blade. I evaluated each cut for tearout on the face of the material and whether the bottom of the cut was flat and smooth, including scoring at the corners. The Bosch 24-tooth set produced some tearout on the plywood, but none on the melamine. The overall flatness of the cuts was fair, but there was no scoring.
