Metabo GE 700 or GE 900 for portable polishing?

[9secz]

I have been using my pneumatic die grinder with 4" buffing wheels to polish the lips of deep dish auto wheels, but the grinder lacks torque. I'm now considering an electric model such as the Metabo GE 700 or Makita GD0800C (7000 rpm and up) or the Metabo GE 900 (2500 - 6000 rpm).

It seems like the GE 900 is what I want in terms or torque, but the max speed is a bit slow for all my 4" wheels. Is 6000 rpm enough to cut and finish polish aluminum wheels with a 4" buff?

Would one of the high speed grinders work out better, assuming I can load them such that the wheel speed drops to what I need? Or would their lower torque output make them a worse choice than the beefy GE 900?

Or is the whole idea of using a variable speed electric die grinder barking up the wrong tree? I have a flex shaft that I run with my drill press motor, but the hand piece gets VERY hot after a few minutes. I bought it from Eastwood many years ago.

Well, some months have passed since my post, which drew 212 views but no replies. I'm *very* surprised nobody mentioned this Caswell adapter that I discovered yesterday that will let me use an angle grinder for my application. The Makita 9564CV is 12 amps, variable speed (2800 - 10,500), weighs just 4 pounds, and is roughly half the price of the Metabo GE 900 die grinder I was originally considering.

Yes that is a good option. I use it as it gives more room and the head of the polisher is further away from work. Takes longer to change wheels, but is well worth it in the long run. muzy

Hi, I have a GE 700 and I used it recently to do some polishing. The motor was overheating after few minutes and my Ge-700 with really few hours on it ended at the repair shop... It's a really nice tool but it don't have enough torque for polishing. I will probably buy a GE 900 to do my polishing jobs.

I hope this will help you!
