Ridgid 18V Brushless Reciprocating Saw Review R8647

Ridgid 18V Brushless Reciprocating Saw Tears Through Demo at 3200 SPM

The Ridgid 18V Brushless Reciprocating Saw continues the brand’s push beyond Octane as the latest generation continues its rollout at The Home Depot. There’s a lot that’s familiar about the saw’s design, but it’s the promise of higher performance that’s high on our minds.


  • 1 1/4-inch stroke length and 3200 SPM
  • Extremely fast in wood cutting
  • Orbital action switch
  • Reasonably lightweight and compact


Ridgid 18V Brushless Reciprocating Saw Performance

Ridgid decided to crank things up a notch with the performance on this reciprocating saw. Comparing it to the Octane version, the stroke length moves from 1 1/8 inches to 1 1/4 inches. The stroke rate is also higher, moving from 3100 SPM to 3200 SPM. In fact, that’s one of the best combinations of stroke length and rate that you’ll find in any brand’s cordless model.

To see how that translates to work, we introduced the saw to our Test Track. If you haven’t seen it yet, it consists of three sections:

PTR Reciprocating Saw Test Track

  • 2-inch cast iron
  • Double stud with 4 framing nails
  • 2×10 roofing sandwich (asphalt shingles, galvanized flashing, tar, peel and stick underlayment, 1/2-inch OSB, and 2×10 yellow pine with five framing nails)

We start with a new Lenox Lazer CT carbide-tipped blade for medium metal on the cast iron and switch over to a Lenox Demolition CT carbide-tipped blade for the two wood sections.

When the dust settled, Ridgid finished in a respectable 1:33.05. However, that was actually about 9 seconds slower than the Octane model (1:23.70).

That wasn’t what we were expecting, so we took a closer look at each section. Starting in the cast iron, Ridgid’s aggressive stroke length and speed may have actually hurt its time a bit. It had some trouble getting the blade’s carbide teeth going and took some time to get them cutting efficiently. In fact, feathering the trigger for a soft start helps a lot and can make up quite a bit of time.

Wood is a completely different story. The saw’s time was solid in the double stud (10.69 seconds) and it torched our roofing sandwich in just 17.40 seconds. To put that in perspective, Milwaukee’s M18 Fuel Super Sawzall took just over 20 seconds to rip through the roofing sandwich. That’s impressive!

On the next generation, we’d love to see a variable speed dial come into play for that thick metal cutting. Just don’t mess with the top end speed or stroke length for when we’re cutting in wood!

Ridgid 18V Brushless Reciprocating Saw Design Notes

Size and Weight

Ridgid hasn’t targeted the big 15-amp corded reciprocating saws yet, keeping this model more manageable in its size and weight. At 17 7/8 inches long, it’s about 1/2 an inch shorter than the Octane model.

It’s also lighter by nearly 1/2 a pound. It weighs 6.8 pounds bare and a 4.0Ah Max Output battery brings it up to 8.3 pounds. That obviously jumps up if you use a higher capacity Octane battery, but it’s one of the lighter cordless saws at this performance level.


Ridgid has traditionally had one of the most feature-rich cordless reciprocating saws on the market and that’s not changing with this update.

  • Orbital action switch
  • Tool-free shoe length adjustment
  • Blade release lever on the side of the tool
  • Rafter hook
  • Variable speed trigger
  • Lock off switch
  • LED light
