Ryobi ONE+ HP PBLCS300 Circular Saw

4.7(1,934 reviews across retail listings)

Ryobi's brushless ONE+ HP sidewinder brought a full 7-1/4 in blade to the value platform. It shares blades with every pro saw and cuts standard framing lumber in one pass — the spec that separates it from compact 6-1/2 in budget saws.

Pros

  • Cuts 2x material in a single pass at 90° and 45°, which cheaper 6-1/2 in saws cannot.
  • Tool Box Buzz and owners agree it handles OSB, decking, and stud work without drama on a 4Ah HP pack.
  • Uses standard 7-1/4 in blades from any brand, so a good Diablo blade transforms it.
  • At roughly half the price of pro saws it leaves budget for the batteries that actually determine cordless happiness.
  • The ONE+ ecosystem means the batteries work in 300+ other tools.
  • The electric brake — once a pro-only feature — made it down to this price point.

Cons

  • 4,300 RPM is the slowest blade speed here; cut quality and feed rate trail the pro saws noticeably.
  • It bogs in wet PT and dense LVL where the FlexVolt and XGT saws power through.
  • The stamped-steel shoe flexes more than the magnesium bases upmarket, hurting long-cut accuracy.
  • No rafter hook.
  • Blade-right orientation with the handle geometry gives lefties and sightline-watchers trouble.
  • Under continuous heavy use owners report thermal shutdowns sooner than pro saws.

Common Questions

Why does the full 7-1/4 in blade matter on a budget saw?
It's the spec that separates this saw from compact 6-1/2 in budget saws: it cuts 2x framing lumber in a single pass at both 90 and 45 degrees, and it takes the same standard blades as every pro saw. That means no hunting for odd-size blades and no double-passing your deck joists.
Should I swap the stock blade for something better?
Yes — this is the single best upgrade for the saw. Because it runs standard 7-1/4 in blades from any brand, a quality Diablo blade noticeably transforms cut quality and feed rate, and it partially compensates for the 4,300 RPM blade speed being the slowest in the class.
Can it handle pressure-treated lumber and LVL?
It'll get through, but this is where the budget shows: owners and Tool Box Buzz agree it handles OSB, decking, and stud work without drama on a 4Ah HP pack, but it bogs in wet PT and dense LVL where FlexVolt and XGT saws power through. Under continuous heavy use, owners also report thermal shutdowns sooner than pro saws.
Which ONE+ battery should I run in it?
Any ONE+ pack fits — that's the ecosystem's whole pitch, with the batteries shared across 300+ Ryobi tools. But for a full-size circular saw you want a 4Ah HIGH PERFORMANCE pack or bigger; small everyday packs can't feed the motor enough current for sustained rips.
What features did Ryobi leave out to hit this price?
There's no rafter hook, the stamped-steel shoe flexes more than the magnesium bases upmarket (which hurts long-cut accuracy), and the blade-right orientation gives lefties and sightline-watchers trouble. Notably, the electric brake — once a pro-only feature — did survive the cost-cutting.

Craftsman's V20 flagship sidewinder pairs a Brushless RP motor — up to 75% more power than the brushed CMCS550 it supersedes — with a 2-9/16 in depth of cut that out-specs most 18V pro saws. In Pro Tool Reviews' testing it ripped two stacked sheets of 3/4-in OSB in 20.22 seconds, placing third against far pricier competition while coming in second-lightest, making it one of the strongest value plays in cordless circular saws.

It checks every feature box (electric brake, LED with dust blower, rafter hook, vacuum-ready shoe) and undercuts the big pro brands at $179 bare, with Ridgid's registered Lifetime Service Agreement sweetening the deal.

Metabo HPT MultiVolt C3607DB "The Stud" Circular Saw

Third generation of Metabo HPT's MultiVolt sidewinder (superseding the award-winning C3607DA), "The Stud" spins at 6,000 RPM and adds a Torque Boost button that drops to 4,300 RPM while redirecting power into 40% more torque for LVL and dense engineered lumber. It was the fastest of twelve saws through double-stacked 3/4-in OSB in Pro Tool Reviews' 2026 shootout, and like all MultiVolt tools it can run corded via the ET36A AC adapter.

Flex's 24V in-line sidewinder is one of the sleeper hits of the cordless saw world: 5,800 RPM, a 2-5/8 in depth of cut that clears 3x lumber in one pass, and Pro Tool Reviews' 9.5/10 'elite cutting performance' verdict. The balanced in-line design gives a clear view down both sides of the blade, and with a 10.0Ah Stacked Lithium pack Flex claims up to 610 cuts in 2x4 lumber.

Bosch's flagship ProFactor sidewinder pairs a BiTurbo brushless motor with an onboard HMI offering six speed settings (2,500-5,000 RPM) and an Eco mode that stretches runtime up to 30%. Its party trick is a base that rides Bosch and select third-party guide rails with no adapter, and it keeps full 2x cut capacity across the entire 0-50° bevel range.
