Our take on the Ryobi ONE+ 18V Cordless 5-1/2 in. Circular Saw with 2.0 Ah Lithium Battery

The Ryobi ONE+ 18V 5-1/2 in. Circular Saw is a compact cordless trim saw that runs on Ryobi's ONE+ battery platform. It spins at 4,700 RPM, cuts 1-11/16 in. deep at 90 degrees and 1-3/16 in. at 45 degrees, and bevels up to 50 degrees. At 4.2 lb it is light enough for one-handed trim work, and the included 2.0 Ah battery with INTELLICELL and COOL-CORE electronics is rated for over 215 cuts per charge. It suits homeowners and light remodelers already on the ONE+ system; framers and heavy users will want a 7-1/4 in. saw with more depth and power.

Questions and answers

What can this saw cut?
It cuts 1-11/16 in. deep at 90 degrees and 1-3/16 in. at 45 degrees, so it handles 2-by lumber, plywood and trim. It is not meant for thick posts or deep rips.
Does it come with a charger?
No. The box has the saw, an 18T carbide blade, a hex wrench, a 2.0 Ah battery and the manual. You need a ONE+ charger, which is sold separately.
Will my other Ryobi batteries work in it?
Yes. It runs on any Ryobi ONE+ 18V battery, so it shares packs with the rest of the ONE+ lineup.
How does it compare with a 7-1/4 in. circular saw?
It is lighter and easier to handle but cuts shallower. A 7-1/4 in. saw cuts deeper and has more power for framing; this one is better for trim and sheet goods.
How many cuts per charge?
Ryobi rates the included 2.0 Ah battery at over 215 cuts per charge. Real-world counts depend on the material and blade.

Yes. It bevels up to 50 degrees, with a 1-3/16 in. depth of cut at 45 degrees.
