  • Overall Rating 9.4

It's been a lot of fun for us to see such big improvements in performance from Ryobi with this HP series of OPE. If you've used other Ryobi battery-powered chainsaws, prepare yourself for a cutting experience on a completely different level. With this major overhaul, the Ryobi 40V HP Brushless 18-Inch Chainsaw vaults itself into contention with the top cordless models available.

Overall Score 9.4 (out of 10)

Ryobi 40V HP Brushless Chainsaw Moves Into New Territory With 18-Inch Bar

Ryobi has been unleashed in their development of the HP brushless line and we’ve been impressed with the improvement on the OPE side. With the Ryobi 40V HP Brushless 18-Inch Chainsaw, we want to know how well it stacks up against the other 18-inch models we’ve used.


Pros

  • Excellent cutting power
  • Good balance with a variety of battery sizes
  • Automatic oiler flow adjustment
  • Dual studs for bar security
  • Onboard scrench storage
  • Blow molded case included

Cons

  • Plastic bucking spikes

Ryobi 40V HP Brushless 18-Inch Chainsaw Performance

It takes some serious muscle to cut effectively with an 18-inch bar. It’s a size that represents some of the best gas-powered models for homeowners and gets into the farm and ranch sector. Those are very different power levels, though, and we set out to see which end Ryobi fits in.

Our friend Eli Mosley invited us out to the ranch he works on to help him take down an oak tree that had split. With solid branches up to 14 inches in diameter, it was a great test for this saw. It’s amazing how often he needs work done when we have OPE to review…

When we first pulled the trigger, it didn’t sound like we were getting quite as much chain speed as other 18-inch saws we’ve reviewed. However, its power was evident as we cut through our oak. Getting into the center where the wood is most dense and at its thickest diameter, Ryobi’s HP brushless motor kept the 0.050-gauge chain moving better than our other models. As we continued, it became clear that this saw’s torque offers more muscle than we expected.

Ryobi doesn’t claim a gas engine size equivalency the way some brands do. To us, it feels like it’s in that 42cc+ category. It’s not quite reaching up to the 50cc+ level of farm and ranch models, but it’s very strong and clearly in the top tier of current battery-powered chainsaws.

Ryobi 40V HP Brushless 18-Inch Chainsaw Design Notes

Weight and Balance

With the bar, chain, and half a tank of oil, the saw weighs 9.9 pounds. The 5Ah battery that comes in the kit adds another 4.0 pounds, making your entire setup just under 14 pounds. That’s not out of line with comparable gas saws by the time you add the bar and chain, oil, and gas to their weights.

The design team made the call to go with a wide-entry battery port. We’ve seen some tools get out of balance with larger packs, but this model doesn’t seem to suffer. Whether we used a smaller 4.0Ah or larger 6.0Ah battery, we didn’t feel like we were fighting the saw’s balance.


Battery Port

Dual Stud Bar Nuts

Tool-free bar tensioners are convenient, but as we get into these larger saws, we really like the additional security of dual studs and bar nuts to secure them. That’s what Ryobi goes with on this model and they add the convenience of on board storage for your scrench.

It Comes With a Case!

There’s a pretty nice blow molded case that comes with this chainsaw. With the scabbard over the bar and chain, it sits down into the case where it has some additional protection during transport. It also keeps any oil from getting all over the place. Clean it out and let it dry from time to time so it doesn’t build up too much.

Blow molded case

If you’re not going to use the saw for a while, go ahead and turn the automatic oiler all the way down on the bottom to minimize and leaking. Just remember to dial it back up some when you’re ready to cut the next time.

Bucking Spikes

The only real downside is that the bucking spikes on this saw are plastic. We don’t mind that so much on smaller saws, but we like to see metal on these higher-performance models.

Additional Features

  • 0.050-gauge, 3/8-inch pitch chain
  • Mechanical chain brake
  • Rapid charger and 5.0Ah battery included in the kit
  • Compatible with all Ryobi 40V batteries

Ryobi 40V HP Brushless 18-Inch Chainsaw Price

You can grab this Ryobi chainsaw kit at The Home Depot for $329. That includes the saw, 5.0Ah battery, rapid charger, and case. That’s about $20 less than Ryobi’s main competitors’ 18-inch saws. Considering the high performance we’re seeing, that definitely bumps the value rating up for this one.

Ryobi backs the tool for 5 years and the battery for 3 years under their warranty program.

The Bottom Line

It’s been a lot of fun for us to see such big improvements in performance from Ryobi with this HP series of OPE. If you’ve used other Ryobi battery-powered chainsaws, prepare yourself for a cutting experience on a completely different level. With this major overhaul, the Ryobi 40V HP Brushless 18-Inch Chainsaw vaults itself into contention with the top cordless models available.
