Standard angle grinder speeds would likely wreck a scotchbrite pad
just from spinning it. Given any pressure, they'd melt. At slower
speeds, though, they work great, especially with mineral spirits or
WD-40. I keep boxes of 3-M 7447/7448 for use on metal and wood.
Took me a while to work out what ROS is. Now I understand. I probably cannot
use mine for that as it is a little square DeWalt which clips in
quarter-sheets. I use it a lot to finish my work.
Random orbit sanders are all round. Orbital sanders have square or
rectangular pads.
I wonder why they do not make rotary brushes with phosphor-bronze bristles
for the angle grinders instead of just steel. One could be so much bolder
removing stuff.
RPM limits, probably.
I am also pretty sure I saw a "Scotchbrite-like" pad for an angle grinder. I
did not pay much attention, must go back and investigate. It was either
House of Tools or Lordco.
I've seen them for angle die grinders, but those are the slower speed
from what I recall. I've never used one so I don't know for sure. They
seem to be used mostly for polishing.
As we are on the subject: Do you use the sand-paper flap discs in your angle
grinder? I meant those where the sand-paper is kind of layered around the
periphery of the disc and you do not need a plastic backing pad. I tried one
and found that the point of contact with the work piece is quite different
from that of a ordinary disk with backing pad. Did not suit my purposes. Why
are they thought better than the others? None of the shop staff gave me a
definite answer.
Yes, and I love them. They look like they'd wear out quickly but I
don't find that to be true. They cut as well as grinding disks, so I
may not be buying any more of the grinding disks. They don't get into
corners or under ledges quite as well, but that's the only limitation
I've found. The more metalwork I do lately, the more I like flap
sanding disks.
