Quick verdict
For most Ryobi buyers the 18V Brushless 8-inch compact pruning mini chainsaw is the best pick. It runs on the huge ONE+ 18V battery ecosystem, its brushless motor handles pruning and light limbing well, and the compact form is easy to control one-handed for overhead branch work.
RYOBI 18V Brushless 8 in. Battery Compact Pruning Mini Chain
This Ryobi 18V Brushless 8-inch mini chainsaw runs on the ONE+ platform and pairs a brushless motor with a compact 8-inch bar. That combination suits pruning and light limbing where a full-size saw is overkill, and being ONE+ means it shares batteries with Ryobi's broad 18V tool range.

Why you should trust this guide
Ryobi’s cordless saws are popular because they tap into the enormous ONE+ 18V battery ecosystem, and this guide is built to help you pick the right Ryobi for pruning, limbing, or light felling without overspending. I compared the real Ryobi listings and stated features here, and I flagged which results are genuine Ryobi versus off-brand mini saws that showed up alongside them.
I did not physically cut with these saws. My comparisons rely on the manufacturer listings, published features, and battery-platform details, and where a listing is thin I have said so rather than inventing specs. The key thing to keep straight is that Ryobi runs two separate battery systems here, the 18V ONE+ line and the higher-power 40V line, and they do not share batteries.
How we evaluated
For cordless saws, the criteria that matter are cutting power, bar length, and how the tool fits your battery ecosystem. I looked at brushless versus standard motors, bar length to judge cut capacity, and whether a saw runs on ONE+ 18V or the 40V platform. I also weighed included accessories like automatic oilers, chain brakes, and tool-less tensioning that shape everyday use.
I paid attention to honest positioning. A compact 6 or 8-inch mini saw is a pruning tool, not a felling saw, and I graded it that way. The 40V 16-inch model is the one built for heavier cutting. Where an item is an off-brand look-alike rather than genuine Ryobi, I said so, because ONE+ compatibility and support are real considerations.
What to look for
- Battery platform: Decide between Ryobi’s 18V ONE+ ecosystem and its higher-power 40V line, since they do not share batteries.
- Bar length: 6 to 8 inches for pruning and light limbing, 16 inches for felling and larger limbs.
- Brushless motor: Brushless models run cooler, last longer, and cut faster than brushed equivalents.
- Automatic oiler: Keeps the chain lubricated; some mini saws are oil-free by design for simplicity.
- Chain brake and safety features: An automatic chain brake and safety lock are important on any saw you swing overhead.
- Battery included: Confirm whether a battery and charger come in the box, especially on Ryobi tools sold as bare tools.
- Genuine Ryobi versus look-alikes: Off-brand mini saws may not fit ONE+ batteries or carry Ryobi support.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

The picks, reviewed
RYOBI 18V Brushless 8 in. Battery Compact Pruning Mini Chain
This Ryobi 18V Brushless 8-inch mini chainsaw runs on the ONE+ platform and pairs a brushless motor with a compact 8-inch bar. That combination suits pruning and light limbing where a full-size saw is overkill, and being ONE+ means it shares batteries with Ryobi's broad 18V tool range.
Reasons to avoid
- The 8-inch bar and mini form limit it to smaller limbs, not felling
- The listing publishes little detail, so confirm whether a battery is included
ONEAND 18V 6 in. Cordless Battery Compact Pruning MINI Chain
The ONEAND 18V 6-inch compact pruning mini chainsaw is an even smaller off-brand alternative, described as a Stens-style replacement-parts-quality tool for lawn and landscape use. Its 6-inch bar makes it very maneuverable for tight pruning cuts.
Reasons to buy
- Stens replacement parts have become a favorite among lawn and landscape professionals than
Reasons to avoid
- This is a third-party brand, not genuine Ryobi, so ONE+ compatibility and support are uncertain
- A 6-inch bar is only suited to small branches and pruning
16 in. 40
This 16-inch 40V Ryobi is the real felling saw here, with a 16-inch bar and chain and a brushless motor for gas-like power. It includes an automatic chain brake, automatic oiler, side-access chain tensioning, and on-board storage, which are the features you want when taking down larger limbs and small trees.
Reasons to buy
- Powerful as Gas: 16 in. bar and chain
- Max Power with Brushless Motor
- Safety First: Automatic Chain Brake
- Easy Use: Automatic Oiler
- Quick Adjustments: Side Access Chain Tensioning
Reasons to avoid
- It runs on Ryobi's 40V system, not the 18V ONE+ batteries, so it is a separate platform
- At 16 inches it is heavier and more saw than pruning tasks require
RYOBI HP 18V Brushless 6 in. Compact Pruning Mini Chainsaw K

- Small off-brand mini saws typically trade durability and support for their low price
What to look for
Pick your battery platform first
Ryobi runs both an 18V ONE+ line and a 40V line, and they use different batteries. If you already own ONE+ tools, an 18V saw lets you reuse packs. If you need felling power, the 40V 16-inch saw is worth committing to its own platform.
Match bar length to the job
A 6 or 8-inch mini saw is a pruning and light-limbing tool, easy to control one-handed. A 16-inch saw is for felling and larger limbs. Buying a mini saw for felling, or a 16-inch saw for small pruning, leaves you frustrated.
Brushless motor pays off
The brushless models here run more efficiently, last longer, and cut faster than brushed equivalents. On Ryobi's HP line, pairing an HP battery unlocks the stated speed gains, so the motor and battery work together.
Genuine Ryobi versus off-brand
Several mini saws in this search are off-brand look-alikes, not genuine Ryobi. They can be cheaper, but they will not fit ONE+ batteries or carry Ryobi's support and parts network, so weigh the savings against ecosystem fit.
Safety and oiling features
For anything you cut overhead, an automatic chain brake and a safety lock matter. Automatic oilers keep the chain healthy during use, while oil-free mini saws trade some chain longevity for simpler operation.
Our verdict
For most Ryobi buyers the 18V Brushless 8-inch compact pruning mini chainsaw is the best pick. It runs on the huge ONE+ 18V battery ecosystem, its brushless motor handles pruning and light limbing well, and the compact form is easy to control one-handed for overhead branch work.
FAQs
For most homeowners doing pruning and light limbing, the Ryobi 18V Brushless 8-inch mini chainsaw is the best all-around pick, largely because it taps the huge ONE+ 18V battery ecosystem. If you need to fell larger limbs or small trees, step up to the 40V 16-inch brushless saw.
No. Ryobi's 18V ONE+ line and its 40V line use different, incompatible batteries. The mini pruning saws here run on 18V ONE+, while the 16-inch felling saw runs on 40V. Choose your platform based on the tools and batteries you already own or plan to buy.
A 6 or 8-inch mini saw is ideal for pruning, trimming, and light limbing, and it is easy to control one-handed. It is not designed for felling trees or cutting thick logs. For those heavier tasks you want the 16-inch 40V saw instead.
Off-brand mini saws like the ONEAND and Supstable can be cheaper and offer features like swappable bars, but they are not genuine Ryobi. They will not use ONE+ batteries or carry Ryobi support, so they suit occasional light use more than reliance in the Ryobi ecosystem.
ONE+ HP is Ryobi's higher-performance version of its 18V platform. On the HP 6-inch mini saw, Ryobi states up to 40 percent faster cutting when it is paired with an HP battery. The tool still works with standard ONE+ packs, but the speed gains come from the HP battery pairing.
