Went to Home Depot and bought this set in a pinch, since the blade that came my tool started showing serious wear after 1 month of use of plunge cuts in hard cherry wood flooring and about 20+ nail cutoffs. Using this Dremel blade for less than a week of light usage, it looks worse than the cheapo blade that came with my tool! Besides about 20-30 plunge cuts into the cherry wood flooring, I used it for one nail (by accident, the nail was in the wood I was cutting), and you can see from my pictures the results. In the first photo, blade #1 is the original cheapo blade (which still has some teeth after 1 month), blade #2 is this Dremel blade (almost completely worn out), and blade #3 is the unused dremel blade for comparison. In the second picture I just show the worn out Dremel blade next to an unused blade. To be fair, I've only been using the oscillating tool for a little over a month, so I'm not sure how these blades compare to other brands. But I do know that compared to the one that came with my set, this performed much worse. For the price, I would have expected better quality and more longevity.

These work well for accomplishing work in tight spaces. But I find that the are not especially durable. A few uses and their shot. Which makes them expensive to use. The metal just seems to wear down quickly.
