I bought this 6" Skilsaw dado set 15 years ago and used them at that time for a set of bookcases. It's a good set and the blades are sharp. I recently started a project prompting me to buy the expensive Freud dial a dado set and so I no longer need them. and will give them to whoever asks first free of charge. Feel free to call with questions (978) 869-6040 -DannyB
