Bests & Worsts Reviews from Amazon

I run a cabinet install business. My guys mostly cut out for outlets and plumbing lines in the backs of cabinets, 1/2" plywood and particle board. I run DeWalt, Milwaukee, Dremel and Rockwell. So the blades do fit all of these tools. Typically a blade will last about one week. Went through 2 blades per day. They just don't seem to hold up. Guys burned through the entire box in a week. If you don't use your blades that often, then buy these. But for professionals they just don't hold up.
