Incredibly, after using Dremel’s rotary tools for years I somehow never stumbled across the chuck accessory until today. This replaces the standard quick-change collet to allow installation of most any accessories without the use of a wrench. Not only does it allow for quick accessory changes, it opens up a bit the range of accessories you can install.
Dremel says it “accepts all accessory bits with 1/32″ to 1/8″ shanks” and works with the following rotary tool models:
Of course, you can chuck other items in there as well, as I’m sure you’re imagining right now. I can’t believe I didn’t find this earlier. Street pricing starts around $7.
