The cutoff wheel is one of my favorite tools for use on a Dremel. But, the little discs do not last long when cutting on a piece of sheet metal and frequently need to be changed. That means I need to have a screwdriver at hand to remove the small screw that holds the disc in place, and to tighten the new disc onto the mandrel. This Instructable will show a simple modification that should be standard on every Dremel. The only thing needed to make this modification is a grinding stone. One attached to a Dremel will do the job.
Step 1: Screwdriver Options
I usually use a very small screwdriver, but I also discovered the middle screwdriver bit on my Leatherman PST will also do the job in a case of necessity.
