I used Hitachi grinder brfore I purchased this grinder to cut porcelain tile. The Hitachi use to break tiles when used . The Milwaukee is by far better cut tiles with no issue.

I am restoring a 77 F100. A lot of grinding, sanding & cutting the last 7 months. The grinder is Perfect. Still have a Milwaukee grinder (running) from the 80's

Milwaukee makes great products and this grinder doesn't disappoint. I'm using it on metal and wood projects without a hitch. The tool is comfortable to use and control and changing grinding wheels is easy.

This is my second angle grinder. I bought an inexpensive Ryobi without reading its limitations - such as metal cutting. So, I did my research, read the reviews and looked at the user manuals Home Depot provides on the product listing. The Milwaukee had strong reviews and did everything I needed. Additionally, it has a five year warranty. Once I began using it I was impressed by not only its cutting but it's ability to grind and sand. I would definitely recommend it.

I admit I am biased toward Milwaukee but I'm not a rabid fan and my decision ultimately came down to personal user preferences. I say that because all the good name brand angle grinders are $40-60 and have very comparable features-So you really can buy whichever grinder you feel most comfortable with. I also remembered that my last grinder was a Black and Decker (arguably an inferior brand next to Milwaukee, Makita, Rigid or Dewalt) and it has lasted me 15 years of frequent use, so again you should feel comfortable buying whichever feels best.
I went with the Milwaukee because I have to have one of the "click on" type switches because sometimes you have to hold the grinder in a precarious position that makes paddle type switches really inconvenient. I also prefer the switch on top of the grinder's body as opposed to the side so I don't have to reposition my hand after I turn it on.
The grinder's body didn't offer me as nice of a grip as the Makita or Dewalt and I thought that would be an issue when in use but it hasn't been noticeable to me during use. I have medium sized hands and If you have small hands I could see that alone as being the deciding factor for the Makita or Dewalt instead but again it turned out to not be an issue for my medium sized mits.
The weight of the grinder is very good as it doesn't have all of it's weight on the front toward the motor.
The Grinder is balanced enough that with the thicker 4.5" grinding discs you barely get any felt vibration and I can't notice any with my flap discs or cut off wheels.
It's not as noisy as my last grinder but come on, it's a grinder and any grinder you need ear plugs for.
The negative of this grinder is the heat. The aluminum motor housing, the spindle and the spindle nut all get HOT with minimal use. They get hot to the point where I would rather wear gloves when I change out a disc or wheel. I worry about the motor overheating but after two hours of frequent use grinding on metal in a 100* garage it was still fine. Milwaukee gives a 5 year warranty on this grinder so that kind of puts me at ease about the motor getting hot. They probably wouldn't put a five year warranty on a grinder that would has overheating issues is my thought.
I also decided to stay in the $40-60 range because the amperages available in that range are absolutely sufficient. It doesn't make sense to me to spend $100+ for a 10+amp 4.5" angle grinder when almost for the same amount you can get a 6 or 7" grinder that will work MUCH faster than any 4.5" grinder regardless of amps.

Rated 5.0 out of 5.0 by UtahTransplant Handy tool with solid performance
I used this grinder to grind down approximately 100 rebar type steel pieces sticking out of my basement wall. It performed the task as well as could be expected. Never overheated or gave me any issues. Would recommend for small grinding jobs.

Rated 4.0 out of 5.0 by EasyRider Great tool almost perfect
I purchased this angle grinder because my 20+ year old grinder finally died on me. I spent some time doing research into grinders and this one consistently came up with good to great reviews. Here is what I found.
- It's comfortable to hold (well balanced)
- Has lots of power
- Easy to change the attachments
- Long cord
- Not too noisy in the world of grinders
- The placement of the on/off switch. It's on the back near the wheel. That mixed with the fact that it does not easily lock into place means my hand is closer to the wheel for longer than I would care for. I wish it had a trigger instead
- The handle is relatively short. So, if you have big hands like I do then your hands will end up closer to the grinding wheel than you may be comfortable with. Initially I was not but I had work that had to get done and I dealt with it. I have since then gotten comfortable with it but a couple of simple adjustments would have addressed this.
Part of me wishes I spent the extra money on the battery powered one. It has the design that eliminates my dislikes mentioned above. However, it does not have the power this grinder does and if you are like me when you are in the middle of a project the last thing you want to be doing is swapping batteries when grinding or cutting. Also, I really couldn't justify how much extra it was for the cordless.
All together I am happy with the grinder I am just not very happy. Hence the 4 star rating instead of the 5.

Rated 2.0 out of 5.0 by Robert Reconsider....
After much research (mainly, reading reviews) and my recent experience of buying and using another Milwaukee product (M12 drill) I thought that this angle grinder was the best value: quality vs. price vs. weight of the grinder (the 6146-30 was tempting). This was my first purchase and use of an angle grinder. I bought it primarily to smooth the edges of several custom torch-cut plates of 1/4" steel plating. I also cut some masonry. During my project I used four or five discs. The grinder seemed to work OK. However, upon changing discs, I noticed that only one small section of the disc had wear (relatively significant wear, depending on how much the disc was used); all discs had the same wear pattern no matter how carefully I secured the discs to the spindle. It seemed as though the spindle had a wobble in it. Anyway, this is not good for these reasons that seem valid to me: increase risk of disc failure (breaking due to uneven contact, increased potential for personal injury), inefficient performance due to the fact that mainly only 1/4 or so of the disc is actually doing the grinding, premature wearing out of the disc since that one working section will wear out relatively fast. I'll try taking it to a repair shop for warranty service and see how that goes. I regret my purchase.
