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.

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.
This kit pairs the Ryobi ONE+ 18V 4-1/2 in. circular saw with an 18V ONE+ 2.0 Ah High Performance lithium battery. The saw has a compact, lightweight, one-handed design for quick, precise cuts on home and DIY projects. It delivers over 300 cuts per charge.
The maximum depth of cut is 1-9/16 in., enough to cut 2-by lumber, plywood, OSB and laminate flooring in a single pass. The bevel adjusts from 0 to 45° for angled cuts such as corners and trim work. A spindle lock and an on-board hex wrench make blade changes easy.
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.
