Review on Dremel 423E Cloth Polishing Rotary by Luis Penczak

I wanted to clean up my coin collection so I decided to use this wheel along with the red polish that Dremel sells. noticed that the coins became much brighter after polishing. This bit was quite fast and could run quite fast even at low speeds. However, after about 15 minutes of polishing, I noticed that all sides of the blade were black and the white circles were heavily curved. I was a little disappointed that it wasn't very durable. If you're using it for small things like coins, you also have to press fairly hard to ensure all areas are cleaned properly, which is probably why the wheel wasn't working. doesn't last very long. If you want to polish smooth surfaces like plates you can use the Dremel 429 (http://www.amazon.com/Dremel-429-Polishing-Wheel-Diameter/dp/B00004UDHC).
