I know this is a old thread but I'm in the process of purchasing a grinder. I'm trying to decide between Dremel 7700 and 7300. Does anyone know if one is quieter than the other? Also, for the 7700, it comes with other grits/finishes. Which ones do you use on your yorkie? For 7700, low speed is at 10,000 rpm... Is this too strong for a 5.5 lbs yorkie? I'd appreciate any feedback! Thanks! |
