I have a number of Milwaukee M18 tools and wanted the convenience of a no power cord grinder which greatly influenced my decision to buy this. The tool worked flawlessly. I had to cut a groove in concrete about 3/4" wide right up next to a corner of a wall. The Milwaukee 2780-20 was exactly what I needed for this job with the blade guard and hand grip being easily adjustable when changing sides to grind from. I've had this about 3 weeks.

I've used this for a variety of small projects around the house so far and am happy with the performance and it gets the job done... 3 stars and can't recommend because the blade guard/adjustment lever is not at all as pictured - it's junk, not user friendly, and is rusting within the first week (I take very good care of my tools). I've got the M18 Fuel circular saw and Hackzall which have seen much more use and couldn't be happier with those tools but this one definitely misses the mark compared to those.

I purchased this because i already had a battery that came with my circular saw. i paired it with a 9.0A battery and it gave me roughly 30-45mins of grinding time. Really made workflow much easier without have to worry about all he wires crossing the floor. It feels sturdy, and a little heavy but adding the 9.0 battery you will notice additional weight.Though its nothing that won't really hinder you and you'll easily get accustomed to the weight.

I went from a HF Switch grinder to this paddle switch grinder. Of course it was a day and night difference. I like buying old made in the USA tools and restoring them. This grinder is super convenient and powerful for my restoration projects. would highly recommend. There is a switch-lock version too so for those fellas/ladies that don't like the paddle switch you won't miss out.
