Is it okay to use an angle grinder to remove rust from steel wheels? Is it generally considered better to use a wire brush / wheel / cup on a drill? Pros and Cons?

Thanks!

 

You can get high speed wire brushes for an angle grinder:

2-3/4" x .020" x 3/8-24" Twist Knot Cup Wire Brush (Steel)

Best wear impact resistant goggles under your impact resistant face mask.

How rusty are the wheels?

Unless they are rare wheels, steel wheels aren't expensive enough to spend a lot of time on, and to risk having a weakened, failure-prone wheel on the vehicle.

 

There was surface rust on the exterior side that a drill took care of pretty well, but the interior was pitted a little. Nothing too bad - I used an angle grinder for the heavy rust on the interior and I don't think the integrity of the wheel was compromised. They're just old Kelsey-Hayes wheels - nothing spectacular, but I got a good deal on them and wanted to make sure they were in decent shape before putting them to use. I'll post up a picture shortly.
