A beast of a grinder

2 years ago
POWER and SPEED and no cords. This is my second grinder and my experience with my first made me want a couple more of these. They work awesome and have a great feel when using. Grinding, sanding, cutting they do it all and no tether to the wall. Get one and your life will improve.

Yes, I recommend this product.

Handy and Reliable.

easy to assemble, use and handle. Gets into every spot so far when I sharpen blades, clean welds and cut off metal when fabricating. Never slowed down or was under too much load. Battery kept up the whole time and never had to charge during manufacturing. Great product

Make sure you buy the fuel version!

a year ago
I accidentally purchased the non-fuel grinder first....it was junk. I then bought the fuel version I meant to get originally and I love it. Exactly what I expect from my Milwaukee tools! Nothing stops this thing , all the power of my 110v but no cord in my way constantly.

Yes, I recommend this product.

Great tool

This is the tool I’ve been wanting for a long time and it was worth the wait and the money. It’s balanced, powerful, smooth and not too heavy in the hand. Cuts through 8” cast without issue, handles every job i throw at it. Plenty of use out of a 5.0 battery. Recommended!

Purchased to use with a sanding disc for sanding down my deck, this excellent grinder, paired with my 6.0 batteries, tore through layers of unwanted paint and stain in no time. Excellent tool, premium build quality as always, and I’d definitely recommend it to anyone.

Better than dewalt and ryobi

3 years ago
I really like the weight balance and the control. Safely triggers can really mess with usability but i like safety trigger on this. It seems like it was well thought out. It seems like it's got the power. I haven't given it a lot of use to test out the battery life.

Yes, I recommend this product.

Best grinder in its class

2 years ago
Love my new grinder has way more power than the dewalt 20v grinder it replaced, and seems to be easier on batteries too they don’t come off dead as hot as the dewalt used too after being worked hard, love the spark catcher cup for guard when using cut off discs.

M18 Angle Grinder, Paddle sw, with no lock

2 years ago
This is one of the best grinder that I have so far. It is quality built, runs smooth, no shaking, less vibration. I noticed that it is quite heavy for a little guy like me. Messing with the paddle switch is also a challenge, may be I just have to get used to it.

Yes, I recommend this product.

Annoying high pitch whine

3 months ago
I’ve yet to really see it in action, although giving it a whirl out of the box I was unpleasantly surprised to hear a high pitch wine when in use. Sort of loud and obnoxious compared to other grinders I’ve used, but if it performs well, I’ll put up with it.

Best grinder

3 months ago
This is a little bit more, but the rapid stop is nice. This is the second one I bought. I do a lot of metal work and don’t like changing attachments all the time so I bought a second one. It’s nice being able to lay it down and it stopping with in seconds.

Professional, Perfected.

This grinder is tough as nails. The last one went through the ringer, and this one has performed just as admirably. The added braking feature, which my last lacked, is very helpful for maintaining control of your cut. Another stellar design by Milwaukee.

First impressions

3 years ago
Good handy grinder. Excellent for cost. The only complaints are: the gard does not rotate 360 and that limits your cutting angles. The big issue is the safety catch on the paddle switch is a pain and hard to use. It maked the grinder awkward to use.

Yes, I recommend this product.

The best cordless grinder

3 years ago
The 4 1/2" Milwaukee angle grinder is the most powerful battery grinder I've used. It easily holds its own against my corded grinder. I think the only improvement that could be made would be to add a speed selector switch for sanding applications.

Yes, I recommend this product.

Powerful R.A. grinder

I'm impressed with this angle grinder. The balance is good and the motor powerful. I gave it a short test to see if It would bog down or the battery protection would stall the tool. As hard as I ground the work piece, I couldn't make the tool stall.

ABSOLUTE BEAST!

Absolute beast of a power tool. I had the regular M18 and stepped up to the FUEL version. Talk about a great upgrade. The FUEL has a great quick stop when you let off the trigger, and it cuts through just about everything. Highly recommended!

Purchased a 4 1/2"- 5" grinder to replace an old 4 1/2" that I had for years. I find this newer grinder more comfortable than the old one I had and better power. I'm a tradesman and I need tools that I can rely on and Milwaukee is a name I trust.

Great power

Was really surprised with the power it has. Tried bogging it down on stainless at work with a flap wheel and couldn't stop it. Does go through the 5.0 batteries pretty quick with continuous use. Would recommend a 12.0. Overall really impressed.

Best grinders at our fabrication table.

The best grinders at our fab table. We run two of these grinders several hours a day across two shifts, and they never miss a beat. From heavy material removal to light deburring, these grinders keep up with our old corded grinders no problem.

Power hungry grinder, I used 2 8ah batteries

2 years ago
I have an 8ah battery on it and it eats it up quick, great addition to a back up, just make sure you have a back up battery for its purpose. I have two 8ah that I use on it and sometimes when I’m really using it I end up using my 4ah batteries

The fit and feel is great. with a 5ah battery it is still fairly light weight and extremely powerful. Very easy to change grinding disks too, do not even have to take my gloves off. For the work I have done with it the no-lock is perfect.

I put on a 5" diamond blade and cut some cement boards with it. This grinder worked great, cut through the cement boards very easily. Make sure you are wearing safety glasses and a mask, because dust and little stones are flying everywhere.

Absolute beast! This thing rips through everything I use it on, and with the new forge battery I can cut/grind even more. Stops on a dime too which is something new for me as I'm used to the grinder continuing to spin after turning it off.

As expected.

Works like a charm. And the brake kicks in immediately after you’re done cutting. It seems to be a lot smoother of a cut as well. The motor, the function, the stability, all seem on on point. It’s exactly what you’d expect from Milwaukee.

Yes, I recommend this product.
