Today I'm going to review and show you the Milwaukee four and a half inch cut
off grinder tool in action. The kit is model 2680-22. It comes with
the tool, one type 1 cut-off wheel for metal and stainless, a charger two M18 XC
high-capacity, redlithium, three amp hour batteries, wrench,
two guards, one type 1 and one type 27 for your wire brush wheels,
instructions, the handle, and the milwaukee contractor bag. Wowza! Does
anyone say, "Wowza!" anymore? I guess I just did. Let's take a look at the tool.
The handle can easily be mounted on either side of the grinder here, here, or
on top. And it simply just screws in. The guards can easily be put on, adjusted, or
removed without a tool. You know on some grinders you can get lazy about
positioning the guard properly because it requires a tool to move it and that
tool happens to be buried somewhere in the basement or the garage?
This grinder has a very easy to assemble guard. You just line up these
two arrows here, and then you have a guard lock here where you adjust the
position of the guard and can select one of these five detents on the tool .So
you get maximum protection. There's a really nice paddle switch and switch
lock off, and a nicely sized spindle lock here so you can turn the flange nut and
take things on and off. Obviously you can use the wrench if you want to get it
super tight. The spindle thread is five eighths of an inch eleven and the
tool spins at ten thousand rpms. You want to make sure you're using wheels
and accessories that are rated at 10,000 rpm or higher. Max capacity is four and a
half by a quarter-inch. Keep in mind when mounting a wheel if it's
greater than an eighth of an inch, you'll need to flip this flange here over to
make sure that the wheel is properly secured.
The tool is a nice weight and I was cutting a metal cabinet earlier today.
The tool cuts smoothly. There's very little vibration and it starts up
without jerking so it's super nice. I'll show you that later. The kit comes
with one type 1 eighth of an inch cutoff wheel suited for small cutoff and
shallow notching of metal and stainless. You can see I've been using this already.
To use the tool to its full potential you eventually need things like
more grinding, cut-off wheels, sanding discs with backing pads, and even
wire brush wheels .What you need obviously depends on the job and the
materials your grinding, cutting, or sanding. There are lots of options:
There is aluminum oxide, aluminum zirconia bi-cut, ceramic, and I could
probably go on all day, but I won't. Let's talk about the batteries and
charger. The kit includes 2 m18 XC, high-capacity,
red lithium, which are basically milwaukee's lithium ion, 3 amp hour
batteries with fuel gauges that allow you to see the power level.
This one's fully charged. This one I was using quite a bit so it's only got two
lights left. Unlike NiCad batteries, these batteries deliver full power until
they just can't. Then they stop. The batteries have built-in protection so
if the power draw or temperature are too much, the battery turns off and the fuel
gauge lights flash or alternate depending on the condition. I found that
each battery pack charged to 100% from zero in about 40 to 45 minutes with the
included charger. They don't have memory, which is great, because I can
charge them at my convenience or say top them off before starting a job. The
charger that comes with the kit not only charges m18 batteries like this
(these are at 3 amp hour), but also my m18, 5 amp hour batteries
for some of my other tools, and also charges m12 batteries for my 12-volt
tools. The contractor bag is nice and roomy. Lots of room for everything that
comes with the kit. It's got three pockets on each side so you can store
cutoff wheels in here (although I don't really recommend it because you can
damage the wheels), store your wrench as well. The issues I have with these bags in
general is you can't zipper them with one hand,
and when the bag is really full the zippers can be pretty stressed out .
The way they could remedy this is just to add a second zipper. Anyway,
grab your safety goggles and let's see the tool in action.
Overall I really like this kit and milwaukee's created another great tool
for the toolbox. If this video has been helpful, please do me a favor and like it,
which helps other people to discover it. And as always, thank you so much for
grinding ... did I just say grinding? <> Thank you so much for watching
