Ryobi p504G vs p505 vs p506: Circular Saw Comparison
The circular saw is made to cut boards of lumber to size. There are various circular saw models which use different blade sizes; the most common sizes being 6 ½ inches and 8 ¼ inches, but manufacturers also produce smaller-sized 5 ½-inch blades for light-duty tasks. Among the numerous advantages of the hand-held circular saw is its sheer efficiency at cutting boards to size. Unlike the reciprocating saw which produces one cut per two strokes, the circular saw slices whenever the blade is in motion.
Ryobi is a Japanese manufacturer of power tools and outdoor products. This company isn’t one of the most well-known power tool producers, nor is it in the same league as mega-power tool makers like DeWalt or Black & Decker, but their power tools are an impressive bunch. Their line of portable circular saws has garnered rather sizable positive reviews from customers and experts, but what is it that makes their tools worth noticing?
If you’ve used one, you’ve virtually used all three. Ryobi’s P504G, P505, and P506 are essentially the same unit with minor variances between each model. In terms of speed and cutting depths, these three portable circular saws perform similarly. There are slight differences in terms of design, but in the end, the aesthetics of the circular saw are a low priority. We would have loved to see more significant differences between the three models, but unfortunately, we don’t.
This doesn’t necessarily mean that these products are a bad choice, but it does mean that the value you get from purchasing any of these models at varying price tags means you’re getting similar value.
Motor and Speed
In terms of performance, again, there’s not much difference between the three Ryobi models. They all feature an 18V DC/AC motor powered by any of the company’s 18V Li-Ion batteries. On all three units, the circular blade can reach maximum speeds of 4,700 RPM. This isn’t the quickest blade speed available on the market, but it works sufficiently in producing neat cuts.
5 ½-inch Blades and 50° Bevel
Normally, portable circular saws come with saw blades between 6 ½ and 8 ¼ inches in diameter, but Ryobi opted to install smaller 5 ½-inch ones on these three models. Smaller blade size doesn’t necessarily translate to weaker or shallower cuts, but in this case, it means increased difficulty in finding replacement blades. Most customers either have to shop at several hardware stores to find a blade size that fits in these power tools, or they have to purchase them online. Each of these units feature onboard compartments where the blade wrench is stored, allowing for easy blade switches without fumbling for tools.
The 5 ½-inch blade can be positioned between 90° and 50° angles. At their most acute angle, the three Ryobi cordless circular saws can produce cuts of up to 1 9/16 inches. This is definitely on the shallow side, but it’s a reasonable depth considering the small blade.
The overall build of all three Ryobi circular saw models are pretty great. They’re designed with a soft rubber on the main handle, as well as the upper and lower blade covers. Operators will have no trouble maintaining a tight grip on the handle, reducing slippage and the risk of deviation.
Similar to almost every circular saw on the market, the blades on the Ryobi p504G Circular Saw, P505, and P506 are designed for right-handed users with the blade found on the left. The position of the blade offers a 4-inch measuring scale on the right-hand side of the circular saws and a 1-inch width on the left-hand side.
In terms of weight, these cordless circular saws are worthy of the title “lightweight.” The P504G, P505, and P506 weigh 5.75 pounds, 4.91 pounds, and 5.0 pounds, respectively. Despite their lightweight class, these models are extremely easy to control, and the 5 ½-inch blades cut perfectly through pieces of lumber with little to no hiccups.
The most significant difference between the Ryobi P506 One+ Circular Saw and the other models is its laser guide. The P504G and Ryobi One+ P505 Circular Saw don’t come with a laser guide, so don’t expect any built-in systems to assist with straight cuts.
Customers have praised the P506’s red laser for offering guidance in assisting with straight cuts. However, it’s never a good idea to rely solely on a laser guide when making straight edge cuts, so we advise you start off with the time-tested method of measuring twice before cutting.
Battery and Charger
Unfortunately, in order to reduce the retail prices of these three products, Ryobi doesn’t include batteries and chargers. If you used cordless Ryobi products in the past, then you’re in luck since these circular saw batteries can be charged in the same charging dock as their other battery-powered power tools. These three circular saws also utilize the same type of One+ Family batteries, so you’ll also be able to swap batteries between tools when needed.
Normally, a One+ battery takes up to an hour to reach full capacity from 0%. If the battery is used solely to power any of these power tools, users can expect up to 30 minutes of use from a single charge. This, however, means that you’ll need to purchase multiple One+ 18V Li-Ion batteries in order to reduce downtime.
Ryobi Circular Saw Comparison: Bottom Line
We found it quite odd that the differences between each of these units were extremely minuscule. Sure, Ryobi added several tweaks here and there, but these are all essentially the same product given three different model names. The main difference between the three is the P506’s laser guide. Other than this, you’ll get the same value from each of these products that come with different price tags.
You shouldn’t expect to get much use of these circular saws at professional job sites, but for DIY work and home projects, there’s little doubt that these Ryobi saws can deliver.
