DeWalt brush cutters

DeWalt (founded in 1924 and now part of Stanley Black & Decker) is a trade power-tool brand. Its outdoor tools run on the same 18V XR and 54V FlexVolt batteries as its drills and saws, which is the main reason to buy one: a tradesperson already carrying DeWalt packs can add a trimmer without a new battery system.

The DeWalt machines we review

The DCM561PBS is an 18V XR brushless string trimmer with a 33 cm cut, 2 mm twisted line, bump feed, a variable-speed trigger and a high/low speed switch, listed at 6,000 rpm. It is sold as a bare tool, and Amazon.co.uk gives an item weight of 3.6 kg. On 27 October 2026 it cost £144.99 there. It is line-only: a tool for lawn edges, borders and site grass.

The DCM571 is the bigger machine: a 54V FlexVolt brushless trimmer with a 38 cm cut, 2 mm line and two speed ranges (0–5,100 and 0–5,600 rpm). Unlike the 18V model, it accepts a brush blade. UK DCM571X1 kits include a brush-cutter adaptor and blade, and DeWalt sells the DT20654 blade separately for the bare DCM571N. UK retailers list it at 4.6 kg bare; Amazon.co.uk had it at £566 on 27 October 2026.

What DeWalt does well

Trade build, brushless motors and batteries shared with a large range of site tools. The FlexVolt packs also work in DeWalt’s 18V tools.

Things to weigh

The garden range is narrow compared with Stihl, Husqvarna or Makita, and the prices are professional. Without existing DeWalt batteries, the cost of entry is high. For heavy brambles all day, a petrol brush cutter or a twin-battery machine with a bike handle such as the Makita DUR369AZ is better suited.

Who should buy DeWalt
