Craftsman V20 Brushless RP CMCS551 Circular Saw

5(11 reviews)

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.

Pros

  • Placed third in Pro Tool Reviews' stacked-OSB rip test (20.22 seconds through two full sheets of 3/4-in material), beating several saws that cost twice as much.
  • 2-9/16 in cut depth at 90° is deeper than most 18V/20V competitors and clears 2x material at a 45° bevel.
  • Second-lightest saw in Pro Tool Reviews' comparison at 8.74 lbs with a 6.0Ah battery — easy on the arm for sheet goods and overhead work.
  • Automatic electric blade brake stops the blade within 1-2 seconds of trigger release (confirmed in the official manual).
  • Excellent value: about $129 bare with frequent promos (Ace has run it at $99), backed by a 3-year limited warranty.
  • Tool-free depth and bevel adjustments, onboard magnetic hex-wrench storage, and reviewers praised the sightlines to the cut line.
  • 56° bevel capacity with positive stops at 22.5° and 45° covers rafter and stair layouts.
  • V20 is a huge, cheap battery ecosystem sold at every Lowe's and Ace, so spare packs are easy to find.

Cons

  • 5,000 RPM no-load speed trails the 6,000 RPM class leaders, so cuts in dense stock are a touch slower and rougher.
  • Overload protection halted Pro Tool Reviews' full-depth maximum-load cut after 14 inches — it needs a lighter feed rate when buried at full depth.
  • No rafter hook, a notable omission for anyone working off a ladder or framing.
  • No first-party kit with battery and charger — newcomers to V20 must piece the system together separately.
  • Owner feedback says performance depends heavily on battery size; small 2.0Ah packs noticeably starve it.
  • No dust port or collection option, so it's a broom-and-blower affair indoors.
  • V20 tops out at prosumer level — there are no high-output packs, so it can't grow into daily production framing use.
  • Pro Tool Reviews noted minor blade drag during compound miter cuts.

Ridgid 18V Brushless R8657 Circular Saw
$179
Circular Saw

Ridgid's flagship 18V sidewinder replaced the Octane version in 2022 with a brushless motor that Pro Tool Reviews found genuinely capable of replacing a 15-amp corded saw — 35% faster cutting than its predecessor at 5,400 RPM. 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
$199
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.
