An someone recommend a decent dado blade for my Rigid r4512 table saw? I have an adjustable (wobble type), but think its not so good. Also price is a factor also...
To me this would leave a less than flat bottom in the dado.I haven't seen any reviews lately, but when they were more common, the Freud SD20x (6 or 8) set was routinely given the best buy (or equivalent) rating. A lot of folks don't like tool reviews because of the conflicting interest stuff (publishers/advertisers), but I always found them useful, you seldom got to see so many side by side comparisons. Anyway, the SD206 set would be a good one. I noticed something a little different about a new set I saw recently; I think it was an Irwin (at Lowes). It had 1/2 as many chipper blades as you might expect. In place of the missing chippers were spacers (you read that right). The idea was to put a spacer between each of the true chippers to get your width. This worked because the teeth on the chippers they did include were 1/4" wide, so if you had two of them separated by a spacer, the extra wide teeth spanned the gap. Looked pretty cheesy to me, but I guess it works.
A wobble type is a single blade mounted on wedge shaped washers that can be set to cut a dado. The amount of wobble determines the width of the cut. I hope I am describing it properly. Anyway you don't want one, It's hell on your tablesaw bearings and will not give you a flat bottom.Sorry for hijacking, but what is a "wobble type" dado set?
