Pneumatic Die Grinder or Angle Grinder for wire brush wheel

[browntown]

I am in the process of tearing out the interior of my 325e and have found a few bits of rust which I really really hope are not too deep and is just surface stuff. Generally for this kind of job I use a wire wheel, but I think the whole trunk surface under the sound tar is surface rusted (don't know yet, but sure looks that way from what I have off so far). Wire wheels are great but my crappy electric drill is on it's last legs, sooo I wanted to use my big a$$ air compressor and get a tool for the wire wheel that I can use on a big job like the trunk floor. So which one do I get? Die Grinder looks like a sooped up dremel tool, and angle grinder looks like I'll eat through the floor boards.

Should I just save my money and por-15 over the rusty bits?

A die grinder would be great for a wire wheel. Plus they rev like a banshee :)

get a sander with some 150 grip sand paper and use that. Those other tools will make holes in the metal pretty easley.

Thats what I'm worried about though, wire wheels are usually rated < 5000 rpm and even the burly twisted ones are < 10000 rpm and most of the die grinders I'm looking at are 20000 rpm units, and I dont trust my throttle control that much. Do they have a speed adjuster or do you just turn down the compressor outlet pressure?

Angle grinders seem to have more wire wheels available for them in useful sizes like 4", they use a big nut to mount instead of a shaft. <-- I realize that sounds bad

Grapedrink: Can I really grind through the floorpan with a wire-brush?

The regular grinders have kits to make them sand too, would that be more appropriate or a flap brush maybe?

I have been looking for a wire brush wheel ...

I have been looking for a wire brush wheel for my 4 1/2 inch angle grinder with a standard 5/8 in arbor, but can't find one!

Holy old thread batman, generally the "wheels" for your 4.5" grinder are cups. The knotted ones are agressive. Home depot sells both of these:



Don't know what the phillipines has though.

FWIW-Knotted wheel cuts quick. If you use a locking switch 4 1/2, hold on good. If it grabs and gets away from you inside the car your screwed. The nurse at the emergency room will ask wth ate the shit out of you. It will burn to the bone in a instant.
