Rated 4.9 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by Top Quality I put this circular saw to work immediately. The Lithium-Ion battery charges fully within one hour. I began cutting boards I needed for the front deck, and it worked just like it said. Great power and ease of cutting. Really amazing cutting power with a lightweight base. The battery has a long life, so more jobs will get done in the day. Guards help protect the blade if you drop it. Battery fuel gauge display is very helpful, in giving you the run time you have left. Milwaukee continues to make an impressive product. I would recommend this saw to anyone looking to do a professional job. October 22, 2013
Rated 5.0 out of 5.0 by Very handy tool In my humble opinion Milwaukee makes high quality well designed tools and this saw fits right in. I used this saw all afternoon today and got to know it pretty well. I founds lots of pros and a couple of cons: Pros: - Lots of power. It is more like a corded power tool than a battery powered tool. It cut cedar fence pickets and 2x4s without even breaking a sweat. - The brake on this saw is amazingly efficient. When you let the trigger go, it stops very very quickly. Really a plus from a safety perspective. - Depth adjustment is a breeze. - Blade installation is easy and the hex tool needed to get the job done is conveniently attached to the saw. - Battery life is exceptional. I used it for several hours today and the battery still isn't drained. - The fuel gauge on the end of the battery is great for monitoring the charge left. - The led light that shines on the work surface is very bright and really helps you to see the work surface. - While I didn't take advantage of the rafter hook today, it's a neat design that tucks easily away at the top of the saw. - The battery charger that is included is pretty cool. It does double duty and will charge both M18 and M12 batteries simultaneously. If you have any M12 tools, as I do, it's a very handy addition. Cons: - The tool is a little heavy but I suppose that is a sign that it is made from good materials. I suspect it will hold up under abuse. - I found the trigger release mechanism a little cumbersome and it took some getting used to but by the end of the day I was comfortable with it. - I found the spindle lock button to be in an awkward place for me. It's not that big of a deal but something to note. In all, this tool is a cut above when it comes to battery powered tools. It is powerful and the battery life is exceptional. Couple that with the convenience of no power cords and this one is a real winner. I would recommend this tool to the DIYer but I also think the professional would find this saw a go-to favorite tool on the job site. I highly recommend. A+++ tool! October 25, 2013
Rated 5.0 out of 5.0 by Great Saw! I purchased this saw for daily home remodeling and interior/exterior repairs. Great product as always. The rafter hook is nice but I'd rather have a belt hook. My corded circular saws rarely leave the truck anymore. I only use the 4.0 batteries since it burns through the smaller ones pretty quick. I never have any issues since I have several batteries and usually break out a corded saw for all day cutting. My favorite saw. December 8, 2014
Rated 5.0 out of 5.0 by Good Little Saw I was slightly surprised about how well this saw works. It is light, easy to handle, surprisingly powerful, packed with simple easy to use features, and has enough battery power to make it a very useful thing. November 7, 2014
Rated 5.0 out of 5.0 by Awesome Saw The M18 Fuel 6-1/2 in. Circular Saw is the fastest cutting 18-volt cordless circular saw I've ever used. It is awesome and the battery last a long time. I have ripped 16 feet long 2X12 with this tool, this is the best saw I've ever owned. December 25, 2013
Rated 5.0 out of 5.0 by I purchased what I wanted Well I got what I wanted Although it was more pricier than the others I know that I will have this for a good long time I just have to purchase additional blades with more teeth for a fine edge Yes I would recommend it to you and anyone August 28, 2014
Rated 5.0 out of 5.0 by Don't read this review, just buy it! Cuts a 2x6 plank like butter. Whisper quiet when compared to a corded 15amp saw. I wish the bare tool had a bag to hold the tool and some extra blades. Right now I am reusing the orginal box to store the tool. May 28, 2013
Rated 5.0 out of 5.0 by Great saw Same as a worm saw, left or right handed. I'm right handed, like better than traditional circular saws, have had a 8 1/4" Milwaukee since early 80's (love it), this has less power but much more convenient. Quick stop blade is sweet for safety when cutting above your head. January 6, 2013
