WORX WG163 12-inch trimmer and edger
A 12-inch WORX trimmer and wheeled edger with an adjustable shaft and button-fed line.
The WG163 suits close lawn-edge work where adjustment, wheeled edging, and button-fed line have useful roles.
- Good for
- Routine lawn edges and awkward working positions.
- Look elsewhere if
- The job needs a tool approved for heavier clearing.
- The tradeoff
- The 12-inch format favors close work and adjustment.

Why it earns a look
- Telescoping shaft and a 90-degree pivoting head for varied positions.
- Push-button CommandFeed and a wheeled edging arrangement.
Where it asks for a compromise
- The 12-inch format is aimed at close lawn-edge work.
- The exact battery and charger package is unresolved.
Adjustment for the awkward spots
The telescoping shaft and 90-degree head adjustment give the WG163 several positions to compare around a fence line and path border. Those are useful features when the edges are varied. The tool still needs to fit the operator and its approved vegetation.
Choose the line routine you prefer
CommandFeed advances line through a button control. That is a genuine difference from the automatic spool arrangement for the BLACK+DECKER kit. I would choose between them by reading how each head feeds and reloads, with approved consumables identifiable before purchase.
Wheeled edging gives the second function a purpose
The wheeled edging configuration is worth choosing when the path border is part of the regular job. Compare the conversion and operating arrangement with the border itself. A broader cutting width or a heavier-clearing tool would solve a different need.
Living with it in the garden
Use the adjustment positions for the approved task.
Keep the correct refill spool or line identified.
Include the edging conversion in the route when that second function is useful.
