Goes well with tools but I have a few complaints. First, they won't hold bits unless screwed in. That's why one of these is silver now, I took it off after having to tighten it over and over again. One was on my dremel, the other was on the apex tool. Basically, the bit will slowly loosen and slip out of the chuck even when tightened. this with pliers. I sand a lot with my Dremel and obviously these cartridges can't handle sanding rust. The collet was less of a hassle for me at this point. If you grind a lot of rust like I do, you'll save money.
