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

The Ryobi ONE+ 18V 4-1/2 in. Circular Saw is a compact, one-handed trim saw that runs on Ryobi's 18V ONE+ battery system. It weighs 3.4 lb, cuts up to 1-9/16 in. deep, bevels from 0 to 45 degrees, and Ryobi claims over 300 cuts per charge. It suits DIYers and homeowners who want quick cuts in 2-by lumber, plywood, OSB and laminate flooring without dragging out a full-size saw. Against full-size 7-1/4 in. saws it trades depth and power for size and control; against other compact saws it stands out mainly through the shared ONE+ battery platform.

What reviewers say

Owners treat it as a handy second saw for quick cuts and small jobs rather than a main circular saw. They like the light weight and one-handed control, and the ONE+ battery sharing. The common complaints are the limited cut depth and the modest runtime from the small battery.

What people mention
  • WeightPraisedOwners say it is light enough to use one-handed for quick cuts.
  • Cut depthCriticisedReviewers note the 1-9/16 in. depth limits it to thinner stock and 2-by lumber.
  • Battery lifeMixedThe 2.0 Ah pack handles short jobs but runs down on longer cutting sessions.
  • Battery platformPraisedBuyers value that any 18V ONE+ battery works in it.
  • Blade changesPraisedThe spindle lock and on-board hex wrench make swapping blades quick.

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

The saw is part of the Ryobi ONE+ System, where any 18V ONE+ battery works with any 18V ONE+ product. The kit is backed by a Ryobi 3-year manufacturer's warranty.

Questions and answers

What can this saw cut?
It cuts up to 1-9/16 in. deep, so 2-by lumber, plywood, OSB and laminate flooring go through in one pass. Thicker stock needs a full-size saw.

It includes a 2.0 Ah ONE+ battery and a 24 TPI blade. The charger is sold separately.
Will my other Ryobi 18V batteries work in it?
Yes. Any 18V ONE+ battery fits, so you can use larger packs for longer runtime.
Can it make angled cuts?
Yes. The base bevels from 0 to 45 degrees for corners and trim work.
Is it a replacement for a full-size circular saw?
No. It is a compact trim saw for quick cuts and light stock; a 7-1/4 in. saw handles deep or long cuts better.

The spindle lock and on-board hex wrench make it straightforward; the wrench stores on the tool.
