Review on Dremel 520 02 Impregnated Wheels Pack by Dan Bobbert

I used these to polish some rough spots on plastic, they melted the surface as hard as they polished it but I expected the same and in fact the same goes for all small polishes. .They can be used in a Dremel-like grinder or even a standard drill. Polishing pebble looks well impregnated. Heavy use will cause some of the fibers to loosen and wear out the pads themselves, but that's how these types of polishers work. Great for small jobs, even has some weapon specific uses. It's convenient to have two and the price is reasonable.
