Awesome and Powerful
[This review was collected as part of a promotion.] Super lightweight and packs a punch. I have multiple Ryobi tools and this makes a wonderful addition to my collection.

    Great little circular saw! Cut through a 2x4 in about 1 second (including a hidden 10d nail!)
    I’m just a DIYer so I haven’t needed to buy a new circular saw for about 20 years. When I got this 5.5 inch battery powered saw I was amazed at its useful features! First of all, it’s battery powered!! I have cut the cord on my old saw twice and had to replace the plug. I don’t have to worry about that anymore, even if I am cutting something overhead. I was afraid that the 18v system wouldn’t be powerful enough to do the job but it surprised me. Most battery powered circular saws turn at about 4,000 RPMs, this one cuts at 4,700. I guess that’s why it cut through 1x6 pine, 3/8 inch plywood, and a pine 2x4 without any drag at all (even though I later found that I had cut through a 10d nail embedded in the 2x4!). I don’t know how many pieces I can cut on a single charge yet but I have several +ONE 18v batteries that I can switch out if need be. Other handy details about this saw are: rubber non-slip grips and safety lock; easy to read cutting depth gauge on the clear plastic blade guard; easy to adjust bevel; cutting width gauge on the base shoe plate; on-board blade wrench storage; spindle lock button; 3 year warranty. I can’t say enough about this great little saw. It’s probably not hardy enough for daily commercial applications but it’s great for what I need to do. I only wish it had a laser guide.

    Ryobi One+ Circular Saw is another excellent tool.
    Always a fan of Ryobi One+ tools, I got this circular saw (tool only - no battery or charger) to take care of small projects that are a bit far away from an electrical outlet or extention cord reach. I am not a fan of the thin cutting blade - it cuts but not so easily in a straight line - but the construction has some very good design points. The allen wrench necessary to change the blade is handily built into the saw's handle. The depth of cut gauge is molded into the blade guard. And the placement of the battery counterbalances the motor weight nicely.

    Compact, but powerful circular saw
    This review is for the PCL500B 5-½” Circular Saw. I had contemplated buying Ryobi’s High Power, Brushless, cordless PBLCS300 7.5” Circular Saw which was on sale at my local Home Depot Store, but I don’t do that much cutting any more. This compact, circular saw is a better fit for my lifestyle. It cuts 2X lumber, and I don’t foresee needing it for anything larger. I needed a cordless saw to cut a 4’x10’ sheet into two 2’x10’sheets so they would fit inside my PacHybrid Van. The saw is very compact and fairly lightweight so it is easy to carry and to store. I still have my old, corded, larger worm-drive saw for serious work, but I really enjoy the freedom of using newer, cordless tools. I never use the old worm-drive anymore. The larger Ryobi Circular Saw has a place to attach a dust control system which I find very useful for my stationary tools (table saw, compound miter saw, planer, etc.) ; however, I selected this saw for its portability. I won’t be dragging a vacuum with me when I use it, so I ordered this little saw even though it doesn’t have a dust collection port. The box included a Ryobi 18T, 5-½” blade with a 10mm arbor. My local Home Depot stocks blades that fit this saw from 3 other manufacturers with 18T, 30T, 50T or 100T so I am confident that I won’t have any problem finding more blades. Oh and there are slots for an edge guide, but I haven’t found the p/n for the correct one. Both the Home Depot and the Ryobi web-sites have listings for an 18V ONE+ PB505B 5-½” Circular Saw, but my saw saws PCL500B on the box and PCL500 on the saw body. There are a couple videos demonstrating this saw on YouTube, just search for “ PCL500B”.

    It surprised the heck out of me. . .
    The RYOBI ONE+ 18V Cordless 5-1/2 in. Circular Saw (Tool Only) surprised the heck out of me. I’ve used several of the RYOBI tools and have grown fond of their superb performance, but admittedly, I was somewhat skeptical when it came to this circular saw. My skepticism, as I hoped it would be, was unfounded, as the RYOBI ONE+ 18V Cordless 5-1/2 inch Circular Saw performs very well. While it does work with the standard 18-volt lithium battery, I strongly recommend using the 18-volt high performance lithium battery with this saw.

    Handy Well Made Saw
    RYOBI ONE+ 18V Cordless 5-1/2 in. Circular Saw (Tool Only) is a good value when owing RYOBi batteries and chargers. The saw is light weight, plugging in a 4 or 6 amp/hr. battery makes the saw feel more substantial by adding weight, yet does not cause the saw to become bulky resting close to the motor projection. The saw performed well for my test cuts through 3/4-inch hard wood and 1.5 in thick solid oak scraps from my shop, closed for the season and Christmas. The motor did not slow through any of the cuts and the thin carbide tipped blade cut smoothly and without effort. The blade guard spring actually offered the greatest resistance. This small light weight saw is really handy for small jobs around the home and yard not having to run extension cords out to repair fences, cut down sheets of plywood, OSB sheets, trimming 2x4’s and shelving when not having or needing a miter saw. RYOBI offers two accessories, not included, for this saw, an edge guide with edge guide lock knob and a vacuum adapter. My advice is to clamp a straight piece of wood or metal to the work piece and use that as an edge guide. It will be more stable and offer a straighter and smoother cut.

    Light weight
    Ryobi Cordless Circular Saw. 5 & 1/2" blade (included). Has a blade lock to help install the blade. This package is a saw only. battery / charger purchased separately. I have several Ryobi tools so I have plenty of batteries. If I'm making only a few cuts, I'll use the 2 ah battery which makes the unit lighter. Has a safety switch which need to be pressed before hitting the trigger. Adjustable blade by angle and depth. The base of the saw has a quarter inch edge so it easily slides along a straight edge. Package includes a allan wrench used to install the blade. I like the combination of the guide handle and push handle. Makes it easy to use. The blade goes deep enough to cut through a 2 x 4.

    Great little saw!
    This is such a great little saw! The light weight makes it easy to control and will not wear you out. Has the traditional blade guard to prevent injury. Other safety feature is lock-off button. With a 1 11/16" cut depth this is good for most 2 X 4 wood. The width of scale seems fairly handy. It allow a cut to be made by using the scale on the saw with no stop and measuring needed. I am a DIY person and I find this saw very handy. I strongly recommend this saw. Wow a 3 year guarantee. Would make a great gift.

    Great Lightweight Saw!
    I really like that this saw is lightweight. With the 2 amp battery it only weighs 5lbs 7ozs. This makes it much easier when sawing overhead or in awkward positions. Even though the saw is lightweight it is very powerful. I was easily able to cut through 2X12 pressure treated joists. Even when the battery got down to 1 bar the saw still quickly cut through the 2X12. The only thing I did not like about the saw was the location of the blade on the left side of the saw. Product descriptions don't really point this out. It was awkward for me as a right-handed person to use the saw.

    Great saw for one+
    The Ryobi One+ 5¼ inch saw is another in the great line of One+ tools. I own many of them and this performs just as great as the rest of the line that I own. First off though understand that this is not the big 7¼ corded powerhouse that Ryobi sells. I put a picture of the two of them to show the compact size of the cordless One+. I installed a 3 amp One+ battery (not included), in the slot and perform a couple of test cuts using the provided 18 tooth saw blade. One on a ¾ inch piece of plywood and the other on a 2x4. How does the saying go, it cut through like butter, and the cuts where smoother than I expected with that saw blade. I haven’t had time to use it enough to see how long the battery will last, but I have 3, 4, 6 and even 9-amp batteries so I am not worried about finishing a job.
