If you don’t already own a Dremel, I will be personally offended if you don’t take advantage of this Prime Day deal. The Dremel 4000-2/30 includes 160 accessories and a flex shaft attachment, and is down to an all-time low $74 today. For context, it usually sells for $133, and hasn’t dipped below $109 all year.
Even if you don’t have any immediate projects that call for it, you can at the very least use it to make a mean Jack-O-Lantern in the fall.
