There may be people out there who would like to know how to use Dremel tools on steel (and carbide) but wouldn't know where to begin. This is a video explaining a little of what I have learned about these tools and how I have used them. These are very inexpensive and versatile little tools. I use them mostly to shape and sharpen cutting tools.
Sorry about the noise blocking out what I was explaining. Basically I was saying that I am careful not to touch the wheel against the web of the drill bit. That can be thinned later. Also when sharpening the straight edge of a normal drill bit I imagine a line intersecting the middle of the wheel through the arbor and use that line as a reference for the final edge to be cut. Otherwise the angle will not be consistent.
