At a glance
DeWalt’s 18V XR range is one of the most comprehensive cordless platforms available in the UK, and the DCMHT563 sits comfortably in the upper-mid tier of their hedge trimmer offering. The brushless motor is the headline specification here – brushless motors run cooler, last longer and deliver more consistent power throughout the battery’s charge cycle than brushed equivalents, and on a hedge trimmer it translates to noticeably smoother performance on tougher material. Paired with a 550mm dual-action blade and a 19mm tooth gap, the DCMHT563 is positioned as a serious domestic trimmer capable of handling hedges that lighter tools struggle with.
The body-only format places it above entry-level cordless trimmers but comfortably below the professional tier. For existing DeWalt 18V XR users the value proposition is clear – no battery or charger needed, and the tool integrates seamlessly into a platform that covers everything from drills and circular saws to multi-tools and sanders. For those new to the platform, a battery and charger starter kit will be needed alongside the tool.
Overview and first impressions
The DCMHT563 feels immediately purposeful in the hand. At 2.9kg body-only it is not the lightest trimmer available, but the weight distribution is well managed – the balance point sits close to the rear handle rather than being blade-heavy, which makes sustained work noticeably less tiring than the weight figure alone might suggest. The front D-handle is ergonomically shaped and provides good control across cutting angles. Both handles have a soft-touch overmoulding that keeps the grip secure even with gloves.
Build quality is consistent with DeWalt’s XR standard. The blade guard is robust and clips cleanly, the blade itself is hardened steel with laser-cut teeth, and the overall assembly feels like it will absorb the knocks and abrasions of regular garden use without issue. The tool lock-off requires simultaneous engagement of a safety button and the trigger – natural to operate once familiar but secure enough to prevent accidental activation. There is no blade speed adjustment on this model, which runs at a fixed 2,800spm – faster than many competitors at this price point.
One detail worth noting is the blade tip design. The DCMHT563 has a rounded tip profile with a protective moulding that prevents the blade teeth from catching on walls, fence posts and hard surfaces at the end of cutting strokes. This is a practical feature on any hedge trimmer used near garden structures, and it works well in practice – the tip glides past obstacles rather than snagging. The blade also features a hardened coating that resists resin build-up from sappy hedge material, which keeps the cutting performance consistent across a longer session without needing to stop and clean the blade.
The 550mm blade and 19mm tooth gap mean this tool will attempt to cut material that lighter trimmers would simply deflect. On severely overgrown hedges with stems above 20mm, monitor the motor temperature and allow cooling periods rather than running continuously. The brushless motor is more resilient than a brushed equivalent but sustained heavy cutting on very thick stems generates heat. A few minutes off between passes on the toughest material prolongs blade and motor life significantly.
Specifications and scores
How it performed in our tests
We tested the DCMHT563 on three hedge types: a 5m run of established privet with stems up to 18mm at the base, a formal box hedge requiring precise shaping, and a mature mixed garden boundary hedge containing hawthorn, field maple and blackthorn with stems reaching 22mm. All testing was done with a 4.0Ah XR battery.
On the privet the brushless motor advantage was immediately apparent. The DCMHT563 moved through stems up to 18mm with no hesitation, maintaining blade speed where a brushed motor would have audibly loaded and slowed. The 550mm blade covered the privet run efficiently – noticeably faster than a 520mm tool on the same material simply because each pass covers more hedge. Finish quality on the privet was excellent, with clean cuts that did not bruise or tear the surrounding foliage. The 2,800spm blade speed contributes to this – faster blade movement means less dwell time on each stem and a cleaner overall result.
On the box hedge the longer blade required slightly more attention to maintain precise lines compared to a shorter 520mm tool, but once the technique adjusted the finish quality was very good. The DCMHT563 is not the ideal tool for intricate topiary work – a shorter, lighter trimmer is more forgiving for tight geometric shapes – but for maintaining a formal hedge surface it delivers clean, accurate results. The mixed boundary hedge was where the brushless motor proved most valuable: the 22mm hawthorn and blackthorn stems that would have stalled many tools were managed with sustained effort but no jamming.
Vibration levels throughout testing were low and consistent – the brushless motor runs noticeably smoother than comparable brushed tools, and the dual-action blade design keeps vibration minimal during cutting. After 40 minutes of mixed trimming with the 4.0Ah battery, hand fatigue was modest given the tool’s weight. The ergonomic handle design contributes to this – DeWalt have positioned the grip and balance point thoughtfully, and the result is a tool that feels manageable across a full garden session rather than tiring after the first 15 minutes.
The 550mm blade excels on long straight runs but requires more care on corners and shaped sections. Approach shaped sections with shorter strokes and let the blade tip do the precise work rather than trying to swing the full 550mm length around tight angles. Once the main faces are done, switch to short precise strokes for corners and top edges to avoid over-cutting.
Battery system and runtime
The DCMHT563 runs on DeWalt’s 18V XR platform – one of the largest cordless tool ecosystems available in the UK, with compatibility across an enormous range of professional and domestic tools. XR batteries are available in capacities from 1.5Ah through to 6.0Ah and are widely stocked by UK retailers. The brushless motor uses battery charge more efficiently than a brushed equivalent, which means runtime figures are genuinely better than the motor’s power output might suggest.
Performance and limitations

- 2.9kg – heavier than lightweight alternatives
- Single speed – no variable control
- Existing DeWalt 18V XR users
- Medium to large gardens with established hedging

- Gardeners prioritising long tool life and efficiency
- Small gardens needing light, manoeuvrable trimmer
- Intricate topiary or close-shape hedge work
- Budget buyers new to cordless platforms
The DCMHT563 is the better trimmer in almost every measurable respect compared to entry-level 18V brushed tools. The brushless motor is not a marketing specification – it makes a tangible difference to cutting performance on tougher material and to the consistency of power delivery as the battery discharges. For a gardener with significant hedging to manage, the step up in capability over a lighter, cheaper tool is worth the price difference. The 550mm blade covers ground quickly on long runs, the 19mm tooth gap handles the sort of stems that domestic garden hedges regularly present, and the DeWalt XR ecosystem means the battery investment serves a broad range of tools.
Where it falls short is exactly where the specification suggests it would: fine topiary and intricate shaped work, where a shorter, lighter tool with a slower blade gives more control. The DCMHT563 is a capable workhorse for the well-stocked garden, not a precision instrument for detailed ornamental work. Understanding that distinction makes it straightforward to judge whether it is the right tool for your situation.
A genuinely capable brushless hedge trimmer that outperforms lighter tools on medium to tough hedging. The 550mm blade and 19mm tooth gap make light work of established privet and mixed garden hedges, and the DeWalt XR platform compatibility is a substantial practical advantage. Not the right choice for small gardens or tight topiary work, but for its intended purpose it delivers.
