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

The Ryobi ONE+ 18V 5-1/2 in. Circular Saw is a compact cordless trim saw that runs on the ONE+ battery platform shared with over 300 Ryobi tools. It spins at 4,700 RPM and cuts 1-11/16 in. deep at 90 degrees, with bevels up to 50 degrees. At 4.2 lb it is light enough for one-handed overhead and trim work. It is a homeowner and light-duty saw: smaller and less powerful than 6-1/2 in. and 7-1/4 in. cordless saws, but cheaper to get into and easy to carry. The kit includes a 2.0 Ah battery but no charger, so buyers already on ONE+ get the most from it.

Pros
  • Light at 4.2 lb, easy to control and carry
  • 4,700 RPM and an 18T carbide blade in the box
  • Bevels to 50 degrees for angled cuts
  • Runs on the 300-plus tool ONE+ battery platform
  • 2.0 Ah battery included, with INTELLICELL and COOL-CORE electronics
  • 3-year manufacturer's warranty
Cons
  • 5-1/2 in. blade limits depth to 1-11/16 in., so it won't cut thick stock in one pass
  • Charger sold separately
  • 2.0 Ah battery gives short runtime on long ripping jobs
  • No blade-left or blade-right layout detail; smaller saws flex more in hard material

What reviewers say

  • 4.2 / 511 ratings

Ratings are good but not glowing, averaging 4.2 out of 5 from 11 ratings. Owners treat it as a handy light-duty saw for trim and quick cuts rather than a replacement for a full-size circular saw.

What people mention
  • WeightPraisedOwners like how light the saw feels for one-handed and overhead work.
  • Depth of cutCriticisedThe 5-1/2 in. blade limits it to 1-11/16 in., so thicker stock needs two passes.
  • Battery runtimeMixedThe 2.0 Ah pack handles trim and quick cuts but drains on long ripping.
  • PlatformPraisedBuyers value that it shares batteries with the rest of the ONE+ lineup.
