DEWALT 20V Cordless 22-Inch Hedge Trimmer Review: Cuts Through 3/4” Thick Material
Overview
The DEWALT 20V MAX Cordless Hedge Trimmer with a 22-inch blade and 5.0 Ah battery is built to bridge the gap between consumer-grade convenience and contractor-class cutting performance. It is designed for homeowners and light pros who need a reliable cordless solution for trimming hedges, shaping shrubs, and clearing small, woody growth without the hassles of a power cord or the fumes of gas.
What makes it stand out
Design and ergonomics
DEWALT focused on balance and reach: the long 22-inch blade gives fewer passes on a dense hedge and a longer effective cutting width, while the tool’s center of gravity keeps it stable in both overhead and lateral cutting positions. The unit is marketed at about 7.5 lbs assembled (weight varies with the battery used), which places it in the mid-weight range—noticeably lighter than a gas trimmer, but heavier than the smallest portable battery models.
Performance: motor, blade, and cut quality
The motor is the core selling point: it provides enough torque to consistently slice through branches up to roughly 3/4″ thick without bogging down. The laser-cut, hardened-steel blades are sharp out of the box and maintain an edge that yields clean shears instead of torn foliage — important for both aesthetic results and plant health.
Battery system and runtime
The included 5.0 Ah battery gives this trimmer a distinct advantage in single-charge productivity. In practical terms, users can expect to complete medium-sized yards and multiple hedges on a single battery, depending on branch thickness and cutting style. DEWALT’s 20V MAX ecosystem is broad, so users who already own compatible batteries can swap them between tools; however, larger batteries make the unit heavier.

Safety and controls
DEWALT keeps the control scheme simple: a main trigger with an integrated safety and a secondary lock-off to prevent accidental starts. There is no multi-speed trigger; the tool runs at a single performance profile optimized for cutting efficiency.
Maintenance and durability
The tool is built for seasonal maintenance rather than heavy daily commercial use. Keeping the blades clean, lightly oiled, and free of sap will maintain cutting quality. For long-term use, periodic inspection of the blade bolts and housing for debris and wear is recommended.
Who this is for
This hedge trimmer is best for homeowners with medium to large shrubbery who want a cordless, low-maintenance tool that delivers clean results quickly. It’s also a solid secondary tool for landscaping professionals who need a battery-powered option for noise-sensitive jobs.

What to expect out of the box
Verdict
The DEWALT 20V MAX 22-inch hedge trimmer positions itself as a do-it-right solution: it combines long reach, strong cutting power, and a battery system that keeps homeowners moving through larger trimming chores without cord entanglement. It isn’t the lightest or cheapest option, but for those who prioritize clean cuts, runtime, and the ability to swap batteries across tools, it is an effective and pragmatic choice.
FAQ
Runtime depends on branch thickness and cutting style: for light shaping and thin stems expect 60–90 minutes; for heavy, woody trimming expect closer to 20–40 minutes. Users who alternate between light shaping and denser trimming will typically complete a medium yard on one 5.0 Ah pack.
Yes. Smaller-capacity 20V MAX batteries fit and reduce the tool’s weight and balance, making delicate topiary work easier. The trade-off is shorter runtime, so plan for more frequent swaps if doing a larger job.
The blade is a hardened, laser-cut unit designed to stay sharp for many jobs. Light sharpening is possible with a file or fine file guide, but heavy resharpening or blade replacement is better handled offline or by a service center to preserve blade geometry and safety features.
It will handle stems up to about 3/4″ diameter without stalling, though frequent heavy cuts will reduce battery life and accelerate blade wear. For thicker saplings or continuous heavy clearing, a higher-voltage cordless or a gas-powered trimmer is more appropriate.
Battery trimmers like this model are noticeably quieter than comparable gas trimmers and are similar or slightly louder than many corded electric units. The quieter operation makes it a good choice for residential neighborhoods and noise-restricted areas.
Yes. Because it uses the 20V MAX platform, batteries, chargers, and common parts are widely available from DEWALT and third-party retailers. That makes long-term ownership simpler and gives flexibility to expand into other DEWALT tools.

Okay this turned into a mini-rant but here goes:
I LOVE the cutting power. My boxwood got a real makeover. But — and it’s a big but — the charger that comes with the kit is reeeeally slow compared to rapid chargers sold separately.
Worth buying a faster charger if you’re impatient like me. Also, sometimes the blade cover is a pain to put back on with gloves.
Does the faster charger shorten battery life? I’ve been wary of ‘fast’ options.
Priya — From what I read, DEWALT’s fast chargers manage temp/charge cycles so they shouldn’t harm the battery if they’re the official ones. I’m using an official DEWALT charger so far and all good.
Thanks for the rant — appreciated and helpful. Aftermarket rapid chargers can reduce downtime, but be sure they’re DEWALT-compatible to avoid battery issues.
Official chargers generally have proper charging algorithms. Third-party fast chargers vary — stick to known brands or DEWALT’s own to be safe.
Good point about the charger speed. I got a DEWALT fast charger from a sale and it’s a game-changer.
I have a couple of practical notes that I didn’t see emphasized enough in the review:
1) Blade maintenance: clean sap off after each use or it gums up fast.
2) Storage: keep battery detached during winter.
3) Use both hands and take breaks — that weight adds up.
Otherwise, I’m pleased. Cutting width and finish are very good for the price.
Has anyone tried sharpening the blades themselves? Or do you send them out?
I took mine to a local small-engine shop once — they sharpened and balanced the blades for a reasonable fee. Might try DIY next time.
Agree on detaching the battery for winter. Also store the whole unit in a dry place to avoid rust on the blade.
Solid practical tips, Claire. Sap buildup is underrated as a cause of poor performance — regular cleaning preserves cut quality.
I bought this DEWALT last summer and it’s been great for my front hedge. Cuts cleanly and the battery lasted through most of my yard on a single 5.0 Ah charge. A bit heavier than I expected but manageable.
Pros: powerful, battery included, good finish
Cons: weight and a touch loud
Overall happy with the price vs performance.
Thanks for sharing, Emily — great to hear the 5.0 Ah holds up in real use. The weight (around 11.4 lbs) is a trade-off for the motor size, but many users report it feels balanced.
Yes Marcus, the trigger lock helps a lot for longer stretches. I only switch to continuous when tackling thick sections.
Totally agree. I was surprised the battery lasted as long as it did. Do you use the trigger lock often? I find it helps with fatigue.
Short and sweet: great cuts, battery included, but be ready for the weight if you have long sessions.
Also, the price point ($239.99 on Amazon) felt fair given the kit includes the battery.
Price/value is a common takeaway — the kit offering the 5.0 Ah battery often tips the scales for buyers. Thanks for tagging the Amazon price.
Agreed. I hunted for a sale and snagged it for under $220 — worth watching for deals around spring.
Light humor: Bought this because I wanted my hedges to look like the ones on those ‘perfect suburban’ Instagram reels. Results: 70% perfect, 30% accidental topiary. 😂
In all seriousness, it’s a solid tool for homeowners who want cleaner edges than manual shears.
Love the honesty, Ethan. There’s always a learning curve with power tools vs hand shears — though you’ll get to 90% perfect with a bit of practice.
Practice makes less accidental art 😅
Same here — my ‘topiary experiments’ went strangely avant-garde at first. Now it’s my go-to for edges.
Good review — the 8.9 expert rating sounds fair.
One thing I wish the article dug into more: compatibility with other DEWALT 20V batteries. I have a 2.0 Ah pack from my drill — anyone tried mixing them? Also, price on Amazon was slightly lower when I bought it.
Great point, Marcus. The DCHT820P1 is compatible with DEWALT 20V MAX batteries, so smaller packs will work but expect shorter runtimes. The kit with 5.0 Ah is optimized for hedge work.
FYI if you have a 6.0 Ah (or larger) 20V pack it gives you ridiculous runtime. But those packs are $$$.
I’ve used a 2.0 Ah in a pinch — works but you can feel the difference in runtime and sometimes a slight drop in cutting speed on thicker branches.
Thanks everyone — that matches what I suspected. Might just spring for another 5.0 Ah for peace of mind.
I appreciate that the article noted it’s near-professional power. As a homeowner I don’t need commercial specs, but I want something that lasts and doesn’t feel cheap.
A small nit: the handle could use a little more padding. My hands start to ache after long trimming sessions.
Good tip, Claire. I’ll try that before buying a whole new trimmer 😂
Thanks, Hannah — ergonomics are often subjective but important. We’ve heard similar feedback about grip comfort; some users add aftermarket grip tape for more cushioning.
I added a silicone wrap around the handle — inexpensive and made a big difference for long jobs.
I used electrical tape with a thin foam layer under it — worked surprisingly well and cheap.
Quick question: anyone know if replacement blades are easy to find for this model? I expect to dull over time but want an easy replacement path.
I bought a replacement blade from the DEWALT parts store last season — simple swap with basic tools.
Replacement blades for DEWALT models are typically available through major retailers and DEWALT’s parts site. The DCHT820P1 uses a common blade assembly for that line, so sourcing should be straightforward.
Does anyone have issues with blade binding on wet branches? I use mine after rain sometimes and it feels like the hedge trimmer gets bogged down.
I had that problem once. Cleaning the teeth and a little WD-40 (sparingly) helped. Also make sure the blades are tight — loose blades can cause grinding.
Sofia, wet wood can certainly make cutting tougher and increase blade binding. Try trimming when foliage is drier and use a light blade lubricant occasionally to reduce resistance.
Long one — bear with me, I have a lot of thoughts:
I was on the fence between this DEWALT and a slightly cheaper Chinese-brand cordless. Went with the DEWALT because of build quality and warranty.
After a season of use:
– The motor feels solid and doesn’t bog down cutting up to about 3/4″ branches.
– The 22″ blade is a sweet spot — long enough to do big swaths but still fits into tighter spots with patience.
– Weight: yes, it’s heavier than some consumer trimmers, but that mass helps stabilize the cut.
– Battery life is impressive for the price; the 5.0 Ah included made weekend jobs doable without swapping.
Would I buy again? Yes. It’s not perfect (trigger ergonomics could be better, and it could use a softer grip), but it’s a reliable tool for suburban hedge work.
You mentioned warranty — anyone tried making a claim? I’m curious how smooth DEWALT support is via Amazon purchases.
Thanks for the detailed write-up, Oliver. Your point about mass helping stabilize the cut is noted — useful nuance for readers choosing between lighter vs heavier models.
Agree on the 22″ length — my neighbor’s 18″ takes forever. Oliver, do you store it fully charged or discharge a bit first?
I keep the battery at about 40-60% for long-term storage per DEWALT guidance. Fully charged for jobs, though.
Good tip on storage, Oliver. Mine sat over winter and fired right up after charging — seems sturdy.
