More power arr arr arr !, December 3, 1999
When I saw they increased the amperage rating to 12 , I
just had to have one . I was not disappointed. This little
beast screams. It does get pretty warm though ,if you dial
the speed down and put a heavy load on it. Its really nice
to have so much power on hand in such a compact size. It
blows the other mini's away!

The offroad club that I lead (Longhorn Offroad), has been
building an RTI ramp recently out of 1/4" box steel. For
the uninitiated, an RTI, or Rate of Travel Index ramp,
measures how much wheel travel a particular vehicle has.
We've been using a stick welder, chop saw, and two angle
grinders to build this beast.
I'd been eyeing this grinder for quite awhile, and when we
got sick of having to switch from grinding to polishing
wheels on my friend's DeWalt, I picked one up. Milwaukee
has a great tool in this little grinder. It can flatten
down a weld in about half the time of the DeWalt. With the
cutting wheel, I can cut through steel faster than the
chop saw. It can also cut through automotive frame rails
without a second thought.
My favorite thing about this grinder is the trigger
action. The DeWalt's was slightly awkward and located a
bit too near the wheel for my taste. The Milwaukee's is
larger and easier to work with gloves. It also allowed for
better balance and thus easier operation of the tool.
If you're doing woodwork or anything delicate, I'd steer
clear of this machine. If you do regular automotive
modification or any heavy metalwork, however, pick up one
of these. It is a wonderful tool for everything from
cutting off bolts, to grinding welds, to even cutting
through fully boxed steel.

I like to take on projects as a reason to purchase a tool
and have been wanting a grinder for a long time.
The reason I went with the Milwaukee (besides the
reputation) is this had a lot of power and variable speed,
not found in most grinders.
I was able to rig a hose and a table to this grinder and
use it for wet polishing of granite with the harbor
freight diamond wet polishing pads. worked great and did a
good clean edge on our granite countertops. However since
this is not designed for this task, it only worked well in
the jig I had created (would not work for a regular
polishing application since there is no way to deliver the
water through the shaft ...)
but anyhow I got the grinder I wanted and its performed
flawlessly, although with a tool like this be sure you
always use hearing protection as it can be loud ...

Very comfortable could not bog it down with pressure when
grinding. have owned several other top brand grinders and
really liked the Dewalt. This has much more power and can
be used for longer periods of time without hand fatigue.
The power is impressive. It doesn't rev as quickly as the
size is everything, March 26, 2000

I have had great service from every milwaukee tool I've
purchased over the years and this one is equally well
thoughtout and constructed. I do have some reservations
about this one. It is in no way a "mini-grinder" and if
that is the size of tool you need for your application
.... don't choose this one. In the world of 'bigger is
better' and 'one-tool-can do all'consumerism this one fits
right in. I've been in fabrication and construction for
many years and it is a waste of your cash to try to make
one tool do it all. what this tool is great for is metal
fabrication or sculpting (stone), it is too heavy for wood
and if you already own a 7" grinder/polisher why duplicate
your tools? It is too heavy for intricate work and too
large for tight places. I will use it in my scuplting and
for foundation work and beams. If you're a carpenter I
can't recommend it, try Bosch or milwaukee's smaller
grinders. Better yet don't buy the tool online until
you've talked with someone who has used that particular
tool. I would not buy this tool again for the applications
I had in mind.
