I use a great deal of 1 ⁄4" plywood for drawer bottoms and cabinet backs in my furniture, but cutting dadoes and grooves can be time-consuming because these sheets typically measure less than 1 ⁄

4" thick. So I have to make two passes with my standard tablesaw blade to get the desired fit. But with Forrest’s Special-Width Dado King, I now make those cuts in one pass with amazing precision. Stack the two outer blades of this 8" set together to cut a perfect 3⁄16"-wide groove. Then add any of six magnetic shims to fine-tune the cut. The set also includes a 1 ⁄16" chipper for grooves 1 ⁄4" or wider. The negative tooth-hook angle prevents grain tear-out in hardwoods, veneered plywood, even melamine.
