Ryobi One P505 vs DeWalt DWE575SB Circular Saw | Which is Better

Circular saws empower woodworkers to produce perfectly cut wood that meets the specifications their projects need without the need to invest on table-mounted saws. These circular saws also edge out table saws in portability, enabling contractors to cut through plywood even outside of their workshops and in the immediate vicinity of the construction site.

Both Ryobi and DeWalt, established power tools brands, understand how cutting-edge industrial design matters when it comes to woodworking in general and circular saws specifically. This is why both the circular saws we’re reviewing today deliver both in their performance and in their features.

Ryobi, a Japanese brand, has been in operations since 1943. They’ve started out in die cast production and in printing presses. Their metalwork foundation has led to making power tools by the 1960 and this tradition of theirs reflects in sturdy, solidly-made products like the Ryobi One P505.

DeWalt began much earlier in 1923 and their pioneering work with the radial arm saw reflects on the DWE575SB. The product itself appears ready to take on tougher woodworking jobs despite it staying within the price point home woodworkers are comfortable with.

 Let’s start dissecting how each circular saw delivers the goods and what benefits they’ll give to consumers in our review below.

Quick Summary

Both circular saws will give you your money’s worth in the workshop but each unit has its set of features that allow it to perform best for specific sets of users.

The Ryobi One P505, the smaller and lighter unit of the two, appears better suited for home use. It’s small footprint makes it a darling for women woodworkers since it’s not as intimidating as bigger circular saws.

On the other hand, the DeWalt DWE575SB appears more robust and tougher. It’s more powerful performance and durable form factor will please carpenters and contractors who need a portable tool in their project sites.

Ryobi One P505 vs DeWalt DWE575SB: What is the Better Circular Saw?

Ryobi One P505

Ryobi crafted the Ryobi One P505 with a rubber overmold on the front and side handles for better handling and lesser friction during operation. The rubber overmold provides better grip and handfeel for less fatigue while cutting through plywood and thicker projects like 2” by 4” wood pieces.

User-Friendly

The Ryobi One P505 measures 4.95 lbs at the scales, around 3 lbs lighter than its DeWalt counterpart. It is arguably the lightest circular saw in the market.

It’s frame rests at 13.4″ x 8.8″ x 7.7″ and its compact frame allows greater visibility of the project surface and a better fit for users who demand smaller, less bulky tools.

Power and Performance

The Ryobi One P505 clocks in at 4,700 revolutions per minute. It’s a decent enough speed to help home woodworkers finish their small projects without issue.

Interoperability

The Ryobi One P505 will work with Ryobi’s family of lithium-ion batteries from the P102 to P108. This means users will be able to choose the charge time as well as the operational time their Ryobi P505 can power through their projects.

What We Like

  • Users can pick left-handed or right-handed versions to suit use with their dominant hands.
  • Since the Ryobi One P505 is cordless, it allows users better maneuverability while cutting.
  • This circular saw is relatively quiet providing users with a silky smooth operation while pushing the unit above the project surface.

What We Don’t Like

  • The saw doesn’t come with a free battery.

The Solution

  • Users will just have to use an extension cord while working or buy a battery with a lot of juice along with the circular saw.

DeWalt DWE575SB 

DEWALT 7-1/4-Inch Circular Saw with Electric Brake, 15-Amp (DWE575SB)Fast and Efficient

The DeWalt revs up to a maximum of 5,200 RPM which is 500 RPMs more than the RyobiOne P505. This gives the DWE575SB the power to cut through projects of different thicknesses and different materials like metal and concrete aside from wood.

Light and Tough Build

The DWE575SB circular saw can take the demands of professional-grade projects because of its high-grade aluminum base and casing. While this DeWalt circular saw takes punishment, it remains supportive of users even at prolonged use since it just weighs around 8 lbs. 

Safety

Users can cut through their projects without worry since the DWE575SB features a safety brake that will stop at a notice. Aside from the brake, the DWE567SB also uses DeWalt’s ToughCord system so users do not have to worry about moving to and fro while carrying the saw since the system will keep it working despite the threats of accidentally pulling the cord out during operation.

Organization

The DWE5755SB’s base allows users to store the wrenches for future use. This organizational system makes it easy for buyers to make adjustments and to find the tools easily when it’s time to change the saw blade to another type. 

What We Like

  • DeWalt packaged the DWE575SB with a nice contractor bag for storage and transport of the tool for outside projects.
  • The  DWE575S boasts of a dust blower at the front side to blow any sawdust or chips that might get stuck on the teeth of the saw.
  • The circular saw provides good deep cuts while working the surface smoothly and quietly.

What We Don’t Like

The blade can wobble from time to time.

The Solution

  • Users need to make sure that they secure the blade with the tools tightly to avoid wobble. DeWalt packaged the DWE575S with tools in order to tighten the adjustment of the blade for a tighter fit when necessary.

Ryobi One P505 vs DeWalt DWE575SB: Which is Better?

If we’re going to choose between the DeWalt DWE575SB and the Ryobi One P505, we’ll have to go with the former thanks to its tougher build and its power. The DeWalt DWE575SB simply outpaces the Ryobi One P505 in terms of power output as this unit revs up to 5,200 RPMs instead of the Ryobi’s 4,700 RPMs. 

This small lapse in performance for the Ryobi circular saw would have been forgivable but the DWE575SB also accompanies its brutish power with safety features like the break and the power cord pullout prevention features. 

The Ryobi One P505 comes at roughly half the price point of the DeWalt DWE575SB’s price point but this advantage is only on the surface. Users will have to buy a Ryobi lithium ion battery pack and charger to make the Ryobi One P505 work without the cord and the pack costs roughly more than the unit itself.

For a solid performance without the frills, we recommend the DWE575SB circular saw for this round.

Final Thoughts

Both circular saws will perform well according to your specific needs. For tougher, professional grade woodworking jobs that a contractor enters, the DeWalt DWE575SB will deliver quality cuts while remaining steadfast against punishment.

For smaller, home-based projects the Ryobi One P505 will perform while making it easy for the amateur woodworker. The buyer will just have to keep in mind where they believe the saw will find more action and to buy the best unit that will suit the job site accordingly.
