Best cordless string trimmer edger options for crisp lawn borders

For a clear trim-to-edge conversion, the Bosch UniversalGrassCut 18V-26-500 and WORX WG163E list dedicated edging functions; the WORX WG173E.9 adds a wheeled mini-mower mode.

GGearjury editorial team · Updated 23 October 2026· 8 min

Quick answer

The best cordless string trimmer edger depends on how your borders are laid out. Bosch EdgeSimple is suited to straightforward lawn edges; WORX WG163E offers on-demand line feed, while WG173E.9 adds a third operating mode.

Best for multi-mode versatility

WORX WG173E.9

  • It switches between trimmer, wheeled edger and mini-mower modes.
  • Brushless motor, 33 cm cutting width and tool-free conversion are listed by WORX.

Drawback: This is a bare tool, so a compatible battery and charger are separate.

Best for light carrying

WORX WG157E

  • Its 1.5 kg tool-only weight is the lowest in this selection.
  • The 25 cm head and automatic line feed suit small borders and tight spaces.

Best for a 40V two-battery kit

WORX WG183E

  • The set includes two 2Ah batteries and a charger.
  • It has dual line and a 33 cm cutting width.

Drawback: The listed 2.9 kg weight includes batteries; confirm how that feels for longer jobs.

Common questions

Questions before you buy

What changes the cut width from model to model?

The cutting head sets the width, and a broader path can reduce passes across open ground. A narrower head may be easier around borders and confined planting.

Can a cordless strimmer edge as well as trim?

Some heads rotate into an edging position or include a wheel; others are designed for trimming only. Confirm the exact model feature in its manual.

Will a spare battery from another tool work?

Only if it belongs to the same compatible battery platform specified by the maker. Check the system name and voltage before ordering.

Is the listed weight with the battery?

Weight conventions differ by product page. We identify whether a figure excludes the battery when the manufacturer states that distinction; otherwise compare with care.
