In principle, all original tools and accessories from Dremel are of good quality plus or minus. But also a good markup for the brand. I took for modeling for the sake of a drill 0.8. Suddenly, large drills came in handy. The set is compact, but the case into which the drill is inserted is made of rubber. Drills sit in it very tightly. On the one hand, they will never fall out, on the other hand, it can be difficult to pull out (especially the largest ones), sometimes you have to do this with pliers. But this is not even a nitpick - just a feature.
