DeWalt DCM571 Review

Where the DCM571 earns its keep

This is not a lightweight cordless strimmer wearing a brush cutter’s badge. DeWalt built the DCM571 around its 54V XR FlexVolt platform specifically so it could take a metal blade, and it shows: the brushless motor has enough torque to push through brambles and light woody scrub rather than stalling or bogging down the way many battery-powered trimmers do the moment they meet anything tougher than grass. Paired with the bike handle rather than a loop handle, it also feels more like a proper brush cutter in the hand, with the kind of two-handed control and balance that matters when you’re swinging a blade through uneven ground.

For anyone who already has DeWalt batteries on the shelf from other cordless tools, this is where the DCM571 really makes sense. There’s no fuel to mix, no choke to fight with on a cold morning, and none of the exhaust fumes or two-stroke vibration that come with an equivalent petrol brush cutter. Charge a battery, clip it in, and go.

Where it comes up short

The catch is cost and runtime. A single battery charge won’t match a full tank of petrol for sustained heavy clearing, so anyone tackling large overgrown plots for hours at a stretch will likely want a spare battery in reserve, which adds further expense. And that expense is the real sticking point: this tool is very often sold bare, without battery or charger, so the headline price doesn’t reflect what you’ll actually pay to get it running if you’re starting from nothing. Once a large FlexVolt battery is mounted, it’s also noticeably heavier than a basic electric line trimmer, which matters over a long session.

Who should actually buy this

The DCM571 is squarely aimed at people who already own DeWalt XR or FlexVolt batteries and want a brush cutter that shares that battery pool, or trade users who value cordless convenience enough to accept the higher up-front cost. If you only need to trim tidy lawn edges, a cheaper corded or basic cordless line trimmer will do the job for far less money. But if your ground includes brambles, scrub or rough patches that call for a metal blade, and you’re already bought into the DeWalt ecosystem, this is one of the more capable cordless options that will actually cope with that kind of growth.
