Our take on the Ryobi ONE+ 18V Cordless 4-1/2 in. Circular Saw with 2.0 Ah Lithium Battery

This is Ryobi's compact 18V ONE+ circular saw bundled with a 2.0 Ah lithium battery. The 4-1/2 in. blade and 3.4 lb body make it a one-handed tool for quick crosscuts and trim work, and the 1-9/16 in. depth of cut clears 2-by lumber and plywood in a single pass. It bevels from 0 to 45 degrees and has a spindle lock plus on-board hex wrench for blade changes. Against full-size 7-1/4 in. corded saws it trades depth and power for portability, and it runs on any ONE+ battery a homeowner already owns.

Best forHomeowners already in the Ryobi ONE+ battery systemQuick crosscuts on 2-by lumber, plywood and OSBTrim, laminate flooring and light framing workOne-handed cutting where a full-size saw is awkward
Pros
  • Light at 3.4 lb, easy to control one-handed
  • 1-9/16 in. depth of cut handles 2-by material in one pass
  • Adjustable 0 to 45 degree bevel for angled cuts
  • Spindle lock and on-board hex wrench simplify blade changes
  • Runs on any 18V ONE+ battery
  • 3-year manufacturer's warranty
Cons
  • Small blade limits depth on thicker stock
  • No charger in the box
  • 2.0 Ah battery is the smallest capacity, so runtime is modest under heavy load
  • Not a substitute for a full-size saw on long rips

What reviewers say

Owners treat it as a handy second saw for quick cuts rather than a primary tool. They like the light weight and one-handed control, and note the small blade limits what it can cut.

What people mention
  • WeightPraisedOwners say the 3.4 lb body is easy to carry and control with one hand.
  • Cut depthMixedThe 1-9/16 in. depth clears 2-by lumber, but users find it limiting on thicker stock.
  • Battery lifeMixedThe 2.0 Ah pack is fine for quick jobs but drains under continuous cutting.
  • BevelPraisedThe 0 to 45 degree bevel is seen as useful for trim and corner cuts.
  • Blade changesPraisedThe spindle lock and on-board hex wrench make swapping blades straightforward.
