Review on 60-Piece Brass Wire Brush Cup Wheels Polishing Kit for Die Grinder Rotary Tools, 3MM Mandrel, Polishing Attachment, Cleaning Brush - PHYHOO Accessories by John Carter

Best Chinese wire brushes. I've only used a few so far (cleaning small parts for my resto) but they last just as long as the original Dremels. They even look exactly like the OEM - no weird wire lengths or missing bristles like other vendors. You'll see a bunch of reviews on Revain saying the bristles are flying all over the place. This comes from people turning their rotary instruments to MAX and not using any of the lower settings. Use settings 1, 2 and sparingly on 3 and you'll be impressed. Don't apply too much pressure and you will get good results as well. I mean it's not a metal grinder or grinder types. Slow and steady wins the race and keeps the budget in check. I also bought steel brushes and they work just as well.
