Q & A Which Dado Set for a Radial-arm Saw? Positive-hook Tooth? Negative-hook? Or Should I just Abandon the Idea? I have a stack dado set that I would like to use on a radial-arm saw. This would relieve me from changing blades on the table saw. The outside blades of my dado set have, I believe, a positive hook. Is this acceptable? If I were to buy blades with a negative hook would that be better? Or is my plan to make dados on a radial-arm saw not a good idea? Edwin Van Over Medina, Ohio in using a negative hook on the radial-arm saw, but someone using proper techniques and care while making the cut can use the positive-hook dado set as well.

If you work only in hardwoods and softwoods, the positive hook does the job fine. —Jim Brewer, Freud USA When trying to determine if a certain blade, dado set or accessory will work on your saw, you should first consult the recommendations of the manufacturers.
