I picked this up for hinge fitting on a run of lidded storage boxes I’d built for the allotment shed, and a roundover along some shelf edging going up next to them, and it went through both jobs cleanly. Out of the box it’s better equipped than I expected. Both a 6mm and a 6.35mm collet come included, along with a straight cutter, a wrench and a parallel guide, so whichever shank size the bits already owned happen to be, metric or imperial, both are covered without a separate purchase. No battery or charger comes with it, worth knowing before ordering if this is a first Ryobi tool rather than an addition to a set already owned.

Picked up dry in a shop with no battery fitted, this thing feels heavier and more top heavy than it has any right to. Once a battery’s clipped on, that impression flips, though not entirely. The balance point does move and the whole thing settles better in the hand, but I’ll say plainly what I’ve noticed running it against other cordless trim routers over the years: this one gets tippier as the battery gets bigger than most of them do, and the base is part of why. It’s on the smaller side for this class of tool, which is fine on a wide board and takes more concentration on a narrow edge.

Overview and first impressions

I’ve reached for it constantly since, and it’s worth saying why. This isn’t the router that replaces a full-size plunge router for a long session cutting joints all afternoon. It’s the one that comes off the shelf for a kerf cut, a hinge recess, a roundover on something that needs one right now. Quick edge work like ogees and roundovers is where it’s at its best, light and fast in a way a heavier corded unit never quite manages.

A quick-release lever handles both depth adjustment and taking the base off, one mechanism doing both jobs rather than separate controls for each. Micro adjustment lets you dial in beyond the coarse setting once you’re close, and the base itself is die-cast aluminium rather than plastic, which matters because a base that flexed even slightly would undo the precision the depth system is built to hold once it’s locked in. Depth adjustment on this thing is genuinely excellent, the best thing about it if I’m honest, on par with the better rivals I’ve used. Where it lets itself down slightly is remounting the base once it’s off. It goes back on fine, it’s just a little more fiddly to seat properly than I’d like, more than some other routers manage.

Maximum plunge depth runs to 38mm, plenty for the hinge recesses and the edging both. Speed runs up to 29,000rpm, and it gets through a cut with a fast, confident action rather than labouring at it. A speed dial exists, which is more than some routers this size bother with, though I’ll be honest that it matters less here than the spec would suggest. Trim routers like this one work best with small bits, and small bits don’t ask for the same range of speed a full-size router does with a big cutter loaded up. Nice to have, not the deciding factor.

How it performed in our tests

The clear base plate is a detail worth crediting fully, giving a proper sightline on the workpiece that a lot of routers don’t bother with. Where I’d push back a little is the single LED underneath. Mine’s positioned in a spot that doesn’t line up with where I’m watching on most cuts, working right handed, so it lights the area behind the cut more than the cut itself. The clear base helps you see the piece. The light doesn’t always help you see the line.

The grip took me longer to get used to than I expected. Held the way the moulded grip zone wants you to hold it, control isn’t quite what a traditional knob-style grip gives you. My instinct was to grip further back near the spindle housing instead, which felt more natural, but that puts fingers closer to an exposed spinning bit than I’m comfortable with. Settled on gripping a bit higher up with the other hand braced on the battery, which works fine once it’s a habit, just isn’t how the thing was designed to be held out of the box.

Battery settled on
4.0Ah
Runtime, tested
22 metres in pine per 5.0Ah charge

Ran the battery down myself rather than trusting the runtime claim, and it drains a smaller pack faster than you’d want across a proper session. Settled on a 4.0Ah battery after trying smaller ones first and finding them wanting, which gave a reasonable run time for a session of hinge and edge work without swapping packs halfway through. That said, for the quick jobs this router’s actually built for, a kerf cut here, a roundover there, even a small battery goes further than you’d think, since the job’s over before the battery’s had a chance to matter. A 5.0Ah pack manages around 22 metres of cutting in pine on a single charge, a specific enough figure that it’s worth trusting over vaguer runtime claims that don’t say what was being cut.

There’s no cooling vent visible in the housing, which made me wonder about long-term motor life under repeated heavy use. Ryobi’s own answer to that, when it’s been asked directly, is that they’ve had no reports of overheating or heat-related returns. That’s their word rather than something I’ve been able to test over years myself, worth taking as a manufacturer’s reassurance rather than proof either way.

💡

Fit a battery before judging how it handles. Bare, it feels top heavy and awkward. Loaded up and balanced properly, it settles down considerably, though it stays tippier on narrow edges than routers with a bigger base.

Battery system and runtime

If the bit ever stalls mid-cut, don’t just switch it straight back on. Work out why it stalled first, because restarting a stalled bit can kick back with real force. Most of the time a stall traces back to a bit that’s gone blunt or was the wrong one for the job rather than anything wrong with the router itself, the same lesson that comes up across cordless routers generally.

The parallel guide bolts to the base and keeps the router tracking a set distance from an edge rather than relying on a steady hand alone, and it’s worth knowing that some listings call the same part a side fence. Same accessory, different name depending on where you’re buying from, not two different inclusions to compare against each other.

Warranty runs three years as standard, no separate registration step needed to get the full period the way some other brands ask for. That’s one less thing to remember doing the week the delivery box arrives.

Performance and limitations

This being part of the wider ONE+ platform matters more than it first looks. The battery and charger system already covers a wide range of tools well beyond routers, so anyone already in that ecosystem for other jobs adds this without a new battery purchase at all. Starting from nothing, that’s an extra cost on top rather than a saving, but for an existing owner it’s most of the reason this specific router gets picked over a different brand doing the same job. There’s also the honest trade-off worth naming: a corded router in this bracket generally out-muscles a cordless one, and anyone billing time on site with a corded router already to hand has less reason to switch unless losing the cable specifically solves a problem the cord creates on that job.

Working out of an unheated shed through a proper UK winter, the charging side is worth knowing about specifically. The tool itself will run cold, but the battery wants somewhere closer to room temperature to charge properly rather than being topped up straight off a cold shelf, a small habit that keeps it performing consistently over a few winters rather than wearing out faster than it should. Cleaning wise, a plain cloth is all it wants. Solvents can damage or discolour the plastic housing over time, so skip anything stronger.

Who it’s for and who it’s not for
Who it’s for
  • Anyone already on the RYOBI ONE+ platform
  • Hinge fitting, small joinery, edge profiles and detail work
  • Anyone happy to budget a 4.0Ah battery or bigger
Who it’s not for
  • Anyone billing time who already owns a corded router
  • Sustained work on narrow edges rather than quick jobs

Final verdict, is it worth it

Between the storage box hinges and the shelf edging, it did exactly what a router this size is meant to do and mostly stayed out of its own way while doing it. Buy it expecting the stamina and stability of a full-size plunge router, or even of some pricier cordless rivals with bigger bases, for a long session on narrow edges, and you’ll come away disappointed. Buy it for quick, precise jobs with a battery already on the shelf, and it earns its keep without much to complain about.

Our verdict

A genuinely well equipped router at this price, let down slightly by a small base and an LED that’s in the wrong spot for right handers. Fit the right battery, keep the narrow-edge limits in mind, and it’s a solid entry point into the ONE+ system.
