It’s very light

It is quite light and does not weigh much, it fulfills its cutting function. I had to cut a fairly large 16x12 beam and even though it helped me with the zawzall it helped me cut a part that was getting in the way. very useful the truth
Yes, I recommend this product.

I like the power and paddle trigger but the guard is sometimes in the way. there are not enough positions to move it to for some application. over all well pleased. I would purchase another any day. it is a better grinder than Dewalt.

Simply I loved it

Simply I loved it. The first time I used it was to cut an aluminum plate in a recycling center, at no time did I feel that it reduced its strength or had difficulties cutting (with a grinding disc). It is simply an excellent tool.

Nice tool, but eats through batteries real quick while getting them toasty hot. Too hot to recharge for a bit. However, this beats a corded tool any day. Additionally, I’ve never had a grinder with a stop. That is a sweet addition.
No, I do not recommend this product.

No cords…no problem

What a beast of a grinder. Now it will chew through batteries but, with a couple batteries and no cord performing remote work is possible. It is so nice not having to lug around generators and extension cords to get a job done!

Cordless power!
2 years ago
A great tool to add to the M18 line, I’ve used corded grinders and I have to say this matches longevity and strength to cut. I’ve used it to cut rebar as well as for automotive purposes such as cutting studs and into the frame.

A great grinder for the money
2 years ago
While the grinder is a great addition to my Milwaukee tool arsonal. The biggest drawback is the lack of a dynamic braking system. Other than that downfall it is a great grinder and makes short work of the targeted project need.

M18 Fuel 4-1/2" / 5" Grinder Paddle Switch, No loc

This is my second one. My first one lasted over four years. And was use almost every day. If it was grinding, cutting or wire wheeling. The most handiest tool for a service truck. Along with Milwaukee drills, impacks, ratchets.
Yes, I recommend this product.

Works well but…..

Definitely works well, would’ve liked it to have less plastic like for example the trigger, it feels like if I drop it once the trigger would break, or some other component, other than that it works well and gets the job done
Yes, I recommend this product.

Great tool!

Great tool to have on the work truck! Love the Brushless Motor, but only time will tell! I've had my Dewalt 18v. grinder for 14yrs and had no issues. This just completed my transition to all Milwaukee tools on my work truck!

Left handed use

I am left handed and this grinder allows complete movement of the guard and handle, without tools, to accommodate its use. Lots of power and no lock handle is perfect for grinding in difficult areas without locking it "on".

Best cordless grinder hands down.

Exceptional tool. This grinder is used daily as I am in the elevating device trade. We are always cutting steel and grinding nails and anchors. Lots of fabrication involving grinding. Long lasting even using 5 hr batteries.

Very impressed with the ergonomics of this grinder. While using a 5 amp hour battery it feels very well balanced.
Wish the instructional booklet was a little more clear and straightforward especially for more novice users.

Great tool - Disappointing sales pitch

I bought this thinking I would qualify for the special that stated if you buy a 5.0 A battery you get any tool for free. But this tool was not included in that offering. I’m happy with the tool but not the bait and switch.

Milwuakee m18 fuel grinder

Does great with cutoff wheels, struggles a bit with a 4 1/2 grinder wheel. Great for field work for making cuts or grinding when corded tools aren’t an option. Runs through a 5ah battery in about 15 minutes of normal use.
Yes, I recommend this product.

Solid power

The 11amp m12 fuel cordless grinder is a perfect edition to my arsenal. No more cords for a quick cut. Nice strong power band. And the rapid stop is great for safety and overall time saving by not waiting to put it down.

Cutting thick Sheetmetal

Plenty of torque and fairly easy on battery use. I used it to cut body panels of an older chevy truck with a 4 1/2 cut off wheel and it ripped right through them with no bogging down. Very impressive for a cordless tool.

No Regrets! Come Over to the Red Side

This is my first cordless grinder, most of the time, I am near the work shop, or I towed a generator with me; so I'm loving the freedom the cordless cut-off provides, and the ease of use and light weight of the product.

Working perfectly. Only one point off due to the fact that is not possible to attach any accessory at the shaft level. The mechanism for the blade protection doesn't allow to attach any king of generic dust collector

Great Upgrade from corded 4 1/2 Grinder

Functions exactly as advertised. I've had corded angle grinders for years and this one has doubled the uses. The power seems to match my corded Dewalt pretty much evenly. Can't believe I waited this long to get one.

Great grinder for $$, perfect for pipe welding

Great little grinder to carry with a couple HO batteries up on a scaffold when welding pipe or or prepping small pipe for welds. I have both brush and brushless and both are great. They eat batteries but work great
