Ridgid 18V Brushless Reciprocating Saw R8647

4.6(300 reviews)

Ridgid's brushless flagship recip pairs the class-leading spec combo of a 1-1/4 in stroke and 3,200 SPM with a switchable orbital mode, and Pro Tool Reviews clocked it cutting a nail-embedded roofing sandwich faster than Milwaukee's comparable saw (9.2/10 review score). Tool-free side-lever blade release, adjustable shoe, LED, and rafter hook are all standard, and Ridgid's Lifetime Service Agreement covers parts and service free with registration. At $169 bare it undercuts most premium-brand recips by $80-$120.

Pros

  • Class-leading spec sheet — 1-1/4 in stroke at 3,200 SPM is one of the best stroke/speed combos of any 18V recip saw.
  • Absolutely shreds wood — beat Milwaukee's comparable model through a nail-embedded roofing sandwich in Pro Tool Reviews' testing (17.4 s vs 20+ s), earning a 9.2/10.
  • Orbital/linear selector dial speeds up wood demolition and switches off for clean metal cuts.
  • Outstanding value at $169 bare — $80-$120 less than Makita, Bosch, and Milwaukee flagship recips.
  • Lifetime Service Agreement: free parts and service for life when registered within 90 days — unique among major brands.
  • Owners consistently praise the comfortable grip, easy one-lever tool-free blade changes, and front LED.
  • Light for a full-size brushless recip at 6.7-6.8 lbs bare, with an integrated rafter hook for ladder work.
  • Compatible with every Ridgid 18V battery ever made; MAX Output packs unlock its full power.

Cons

  • No variable speed dial — only the trigger — which makes slow, controlled starts in thick metal harder than on Bosch's flagship.
  • PTR found it needed trigger finesse to get carbide-tooth blades started in thick metal — wood is its strong suit, metal merely adequate.
  • Some Home Depot reviewers report battery overheating and long-term reliability concerns.
  • Needs pricier MAX Output batteries for full performance — older/basic packs blunt its edge.
  • Ridgid 18V is effectively a Home Depot exclusive, so battery deals and service options are limited compared to multi-retailer brands.
  • Ships with a single wood blade — plan on buying a blade assortment immediately.
  • Lifetime Service Agreement requires registration within 90 days and excludes batteries after 3 years — miss the window and coverage drops to the standard warranty.
  • No advanced electronics (no kickback control or adaptive speed) that newer 2025-era flagships offer.

Craftsman V20 Brushless RP CMCS351 Reciprocating Saw
$149
Reciprocating Saw

The flagship of Craftsman's V20 recip lineup, the Brushless RP CMCS351B (launched with the RP line in 2022, superseding the CMCS350) delivers up to 75% more power than the brushed CMCS300 and tops the value class at 3,200 SPM. A two-speed selector, tool-free blade release, and LED light cover the essentials, and Ace Hardware buyers rate it 5.0 stars across 76 reviews — though it skips pro features like orbital action and a rafter hook.
