The Milwaukee M18 FUEL 16" String Trimmer Kit (3046-21HD) is a cordless, fixed-shaft string trimmer built for landscape maintenance pros. Its rear-mounted POWERSTATE Brushless Motor delivers 1.76 HP — more power than a 31cc gas trimmer — and the kit ships ready to run with an M18 REDLITHIUM FORGE HD12.0 battery and charger.

What it does well

POWERSTATE Brushless Motor produces 1.76 HP and reaches full throttle in under 1 second
Adjustable cutting swath from 14" to 16" runs 0.080" or 0.095" line
Three speed settings (0–4,600 / 0–5,400 / 0–6,200 RPM) plus a variable-speed trigger for fine control
Easy Load trimmer head holds 25' of line and reloads in under 30 seconds

Is this the right trimmer for you?

This is a full kit, so it is a strong pick if you want gas-level cutting power without the fuel, pull-starts, or engine maintenance — and you are already on, or moving into, the Milwaukee M18 platform (compatible with 275+ M18 tools). If you already own M18 FORGE batteries and want to save money, look for the bare-tool version instead; this kit includes the battery and charger.
