Ryobi R18CSP-0 18V ONE+ circular saw 150mm
Product description
If you need clean, straight cuts for everyday home and garden jobs, this cordless 150mm circular saw from Ryobi gives you the control to work through timber and plastic with confidence. The R18CSP-0 is part of the 18V ONE+ platform, so it pairs with the batteries and chargers you already own within the system, which makes it a practical addition for DIY and light workshop use 🙂.
With a premium 150mm blade fitted with 18 carbide tipped teeth, you get reliable cutting performance and a good cut finish on suitable materials. It also includes adjustable bevel capability up to 56 degrees and a 4,700 rpm no load speed setting, so you can adapt the cut to different tasks without having to rely on mains power for everything.
Key points
This Ryobi cordless circular saw is designed for long straight cuts, which matters when you are trimming sheets, working on kitchen surfaces, or preparing boards for doors and window openings 🪚. The 150mm blade is built for a smooth result, and the carbide tipped tooth count helps maintain cutting quality over repeated use. You can set up the saw for bevel cuts as well, giving you flexibility for angles rather than only flat 90 degree work.
Because it is sold as a Bare Tool, it suits buyers who already have ONE+ batteries and chargers at home, or who plan to add them later. That can be a more cost sensible way to build your kit gradually, especially if you already own other 18V ONE+ tools. It is also helpful if you want the same battery system across different projects, from wood trimming to plastic cutting where appropriate 🙂.

What’s included
This is a Bare Tool version, which means the package does not include a battery or a charger. The saw is supplied with a premium 150mm blade featuring 18 carbide tipped teeth, so you can fit it and get cutting once you have a compatible ONE+ battery ready. It is compatible with all batteries and chargers across the 18V ONE+ system for home and garden tools.
It is worth bearing in mind that, because it is a bare unit, your runtime depends on which battery you use and the task you are doing. If you are setting up for frequent work, choose a battery size that matches how long you expect to be cutting in one session. For many DIY jobs, this layout is convenient, since you can re use the same battery across your other ONE+ tools.
Who it’s for
It makes sense if you want a cordless circular saw for long straight cuts in timber and plastic, such as trimming timber sheets and working around kitchen worktops, doors, and windowsills. You will likely appreciate the 0 to 56 degree bevel capability when you need more than just square cuts, including angled preparation for fitments. It might not suit you if you prefer a kit that includes everything in one box, since this model is sold without a battery or charger.
It suits DIY users and home improvers who already invest in the 18V ONE+ range and want a consistent platform for tool collection. If you plan occasional cuts, this is a straightforward way to add a 150mm saw to your setup without buying a second power ecosystem. For regular projects where you are trimming, squaring, and shaping boards or sheets, the combination of carbide tipped teeth and adjustable bevels is a practical match 🧰.
