Heavy duty angle grinder
« on: April 05, 2022, 02:05:33 PM »
Can anyone help me in ID'ing this angle grinder? The nameplate is all but wiped clean.

Looks like a Milwaukee, but that's as far as I can go.

I thought the same thing when I saw the picture; Milwaukee. Could be a sander or polisher as well.
No matter how much you cut off, it's still too short

That was my first thought.
The nameplate does have remnants of red on it, so maybe it is Milwaukee.


..... Could be a sander or polisher as well.

Possibly. The RPMs are much slower than my modern angle grinders, but it's pretty heavy to be doing any precision work.

In the top picture, those two black round things with the threaded center. Those are backing pads. It's a polisher. Milwaukee 5530. I hope you've been able to get that cup wire off.

The discs in the background are 7" grinding discs (cheap Cummins brand) that I won't be using. And yes the wire cup comes off easily.

That's good, I been wondering about that. I use a lot of those wire cups. I had the threads of that seizing on this Milwaukee grinder. I got some thin wrenches to fit in there. I keep em with that grinder.
I looked at the schematics for your tool and I didn't see anything that a wrench could engage.
I had the newer Milwaukee 5540, but I gave that to a good friend a few years back.
You say it's a lower speed and those pictures are real good. The shots of that brush cap nails it down. The 5530 diagrams for 1974-82 are a match. The 1968 is different.
I can see where someone would use that wire cup on your tool. Using the regular wire cup on the angle grinder; 11,000 rpm, after some use the little wires fly off like arrows.
