Tim McCoy Posted November 11, 2009 Share Posted November 11, 2009 Hi, Just acquired a used and working Milwaukee 7" buffer ... heavy duty. I would like to know if it can be "converted" into an angle grinder? How much trouble to adapt it to hold grinding stones/wheels? It's a model 5540, 2800 RPM max and is 11 amp ... has a dial speed control. Any help would be appreciated. Tim Link to comment Share on other sites More sharing options...
arftist Posted November 11, 2009 Share Posted November 11, 2009 Save it for buffing or sell it, it will not make a good grinder. A seven inch grinder wants to spin about 6000 or so rpms. You will be wasting your time and ruining an expensive machine. Link to comment Share on other sites More sharing options...
Dragons lair Posted November 11, 2009 Share Posted November 11, 2009 Sorta like converting a 68 VW into a open wheel race car. Ken Link to comment Share on other sites More sharing options...
Tim McCoy Posted November 11, 2009 Author Share Posted November 11, 2009 Thanks guys - just what I needed to know. I guess I will have to find something to buff up or get on my trading hat! I know that it is expensive ... $200 at the online tools stores . . . Cheers, Tim Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted November 14, 2009 Share Posted November 14, 2009 It could make a sander for finishing. The variable speed could come in handy. Look on Craigslist, I have seen some decently priced 9" grinders on there. I bought my almost new B&D Wildcat for $50 at a flea market. Garage sales are another place to find inexpensive tools. I would stay away from Harbor Freight grinders. Plenty of good used tools out there with the downturn in the local building trades. Link to comment Share on other sites More sharing options...
evfreek Posted November 14, 2009 Share Posted November 14, 2009 I seem to remember that the Milwaukee sander and grinder are the same tool. The sander is just missing the guard. Now this is not true for Harbor Freight. Their sander is really just a sander, and it is weak. But you can get a guard from a Milwaukee store or online. A lot of the grinders on the used market do not have guards. I usually pass on these, even if they are good deals, since they suggest that the owner is careless. Anyway, check online or at the store. I think they are the same tool. Link to comment Share on other sites More sharing options...

Tim McCoy Posted November 16, 2009 Author Share Posted November 16, 2009 Milwaukee buffer spins about 2500 RPM ... Milwaukee grinder spins at 9000 RPM zoom-zoom! It won't work to try to convert it - thanks lots everyone!!! Tim Link to comment Share on other sites More sharing options...
