As a hobbyist woodworker I like for my equipment and tools to be accurate, reliable, and easy to use. When building drawers and cabinets a good dado set is indispensable. In March of 2016, I purchased the DeWalt 8” Stacked Dado Set, Model DW7670 from Wood Craft in Parkersburg, West Virginia. Retail price was $149.99.
Over the last several years I have tried working with a Sears, dial type dado blade that only left flat bottom dados when adjusted to 3/4”. Any other setting needed a lot of chisel work to get the desired results. I don’t have that kind of time.
Wood Craft carries all sorts of dado sets by various manufacturers such as Freud and Forrest. I had an in depth discussion with the salesman there about the pros and cons of each and what difference there would be between the various models. I’m a guy that likes quality things but I’m also cognizant that expensive does not always mean better. Pricing of other sets ran from $160.99 to $379.97. By comparison they all would do what I needed and the details were similar, but I went with the DeWalt. I’ve always had good luck with DeWalt products so why not go with what you know?
The DeWalt DW7670 comes in a hard shell case that is nicely organized and the blades are in compartments with plastic wing nuts that keep them from getting loose and damaging themselves on the other blades. There’s even a little pocket for the instructions which is handy. The cutter blades, chippers, and shims are easy to figure out for getting the perfect fit too.
Speaking of fit, I’ve watched a lot of people on YouTube putting on their dado set and making test cuts then having to take the set off again and add or subtract shims a few times to get the fit right.. A simple way to get the setup right before you install the dado set is to just lay your work piece on the table saw top and stack the blades, chippers and shims while they are on the table. until they are flush with the work piece. When the dados match the width of your board you’re done. It’s that simple.
Since I’ve had this dado set, I’ve made about thirty drawers, three stand alone cabinets for the drawers, and two shelf units. They were a joy to make with this kit.
I can’t think of anything that I don’t like about the DeWalt DW7670, it does the job accurately, reliably, and is easy to use. That meets all of my criteria for a good tool. I’m not concerned about warranties generally so I have no comment on that. If I wear this set out I would definitely buy another one.
