The Ryobi One+ P505 18V Cordless Circular Saw is a solid option for woodworking and general cutting tasks. The rubber GripZone handles keep the saw comfortable and secure in your hand, even during longer cuts. A transparent lower guard gives you a clear view of the blade and your cut line, and the bevel adjusts up to 50 degrees for angled cuts. The left-side auxiliary handle adds extra control and keeps your sightline open as you work.
Why Consider This Product?
The Ryobi One+ P505 is a capable cordless circular saw that punches above its price point. It has the features you’d expect from a job site saw without the premium cost.
The saw runs on Ryobi’s 18V ONE+ battery platform, so if you already own Ryobi tools, you can power it with any battery you have on hand. That compatibility alone makes it a practical pick for anyone already in the Ryobi ecosystem.
The GripZone Overmold adds rubber to both handles, giving you a firm grip even when your hands are dusty or sweaty. This makes a real difference when you’re cutting for extended periods or working in tight spots.
The lower blade guard is made from clear polyurethane, so you can see exactly where the blade is making contact with the material. That visibility helps you stay on your cut line without constantly stopping to check your position.
The bevel foot adjusts up to 50 degrees, which covers virtually every angled cut you’ll need for framing, trim, or furniture work. You can lock it in at common angles quickly without fumbling with the adjustment.
The auxiliary handle on the left side gives your non-dominant hand a stable place to rest, which reduces fatigue and keeps the saw tracking straight. It also keeps your hand clear of the blade path.
Features and Benefits
Enhanced Grip and Handling
The GripZone Overmold coats both handles in rubber, increasing friction between your hands and the tool. The grip stays secure whether your hands are dry, dusty, or wearing gloves.
Maximum Visibility
The lower blade guard is made from clear polyurethane, so the blade and the cut line stay visible throughout each pass. You don’t have to guess where the blade is sitting relative to your mark.
Versatile Cutting Angles
The bevel adjustment goes up to 50 degrees, letting you cut compound angles for trim, rafters, and furniture joints without switching tools. The foot locks solidly at your chosen angle so it won’t drift mid-cut.
Improved Control
The left-side auxiliary handle gives you a second grip point, which steadies the saw and reduces wrist fatigue on longer cuts. Its position keeps your line of sight open so you can track the blade against your mark.
Product Quality
Ryobi builds the P505 with a solid plastic body that holds up well to regular workshop and job site use. It won’t feel as heavy-duty as a pro-grade saw, but it’s built well enough for the price and the workload most DIYers and light contractors put on it.
The GripZone rubber doesn’t peel or crack with normal use, and the bevel adjustment mechanism stays accurate after repeated use. The clear blade guard is durable enough to resist the scrapes and knocks that come with cutting sheet goods.
Ryobi backs the P505 with their standard warranty, and replacement parts are easy to find. That matters when you’re relying on a tool regularly and need a quick fix rather than a full replacement.
What It’s Used For
The P505 handles a wide range of cutting tasks around the home and on the job site. The 5-1/2″ blade and 4,700 RPM motor give it enough power for most cuts you’ll need to make in wood-based materials.
Cutting Plywood and Lumber
The 5-1/2″ blade cuts through plywood sheets and dimensional lumber cleanly at full speed. The bevel adjustment lets you dial in rip cuts and crosscuts at precise angles without needing a second saw.
Trim Work and Molding
The clear lower guard lets you see exactly where the blade meets the material, which is a real advantage when cutting trim and molding profiles that need to line up perfectly. The auxiliary handle steadies the saw for the slower, more controlled passes this work requires.
Home Renovation Projects
The cordless design makes the P505 easy to move around a renovation site without dragging a cord through drywall dust or around obstacles. It cuts drywall, OSB, flooring panels, and roofing sheathing without struggling.
DIY Furniture Building
Building furniture requires straight, repeatable cuts, and the P505 delivers that when used with a straightedge guide. The bevel capability handles angled joinery cuts that would otherwise require a miter saw.
