Cordless 20V String Trimmer
Designed for ease and control, the 2-in-1 Westinghouse WST 20V cordless string trimmer and edger delivers power and precision with the freedom of battery powered tools. Skip the hassle of gas engines and the limits of cords. The included 2Ah 20V battery powers an 8000 RPM high speed motor, equal to many gas powered trimmers, for easy cutting of grass and weeds. Perfect for tight spots where mowers and larger trimmers can’t fit and where corded tools can’t reach with a 12 inch cutting swath—wide enough for good coverage, but sized for precise work around landscaping, walls and fences. A foldable wire guide prevents damage to plants or trees. A single line cutting head easily pivots from trimmer to edger, slicing clean lines along sidewalks, driveways and garden beds. Less than 6 pounds, the compact build adds control and reduces fatigue. The shaft easily adjusts 8 inches and the auxiliary handle adjusts in moments for a natural, efficient working position. Automatic line feed eliminates bumping for less trouble and wear. Comes with .065" round line and accepts .080" twisted line. Line replacement is simple with an easy access spool cap using standard sizes. The 2Ah battery runs up to 18 minutes and recharges in an hour on the included fast charger. This cordless lawn trimmer is part of the Westinghouse W20 Series, a set of 20V high performance lawn and snow tools, batteries and chargers. DeWalt 20V MAX and 20V MAX XR batteries also work. Backed by a 2 year limited warranty.
- HIGH SPEED CUTTING POWER: The efficient motor delivers professional results with a line-speed equal to many heavier gas powered trimmers, letting you cut tall grass, thick weeds and slice sharp edges in less time, with less weight and less hassle
- 2-IN-1 STRING TRIMMER AND LAWN EDGER: Quickly switch from string trimmer to lawn edger to cut clean, defined lines along sidewalks, driveways and flower beds with one versatile lawn care tool
-
AUTO LINE FEED: Line advances with the trigger, no bumping required, so you can keep working without stopping to adjust during lawn maintenance and grass trimming
-
CUSTOMIZED FIT WITH LIGHTWEIGHT CONTROL: Weighing under 6 pounds with an adjustable auxiliary handle and a shaft that adjusts 8 inches, this lightweight weed trimmer gives you a comfortable fit in just seconds for improved control and less fatigue
-
BATTERY & CHARGER INCLUDED: The 2Ah 20V battery provides up to 18 minutes of use and charges quickly. Part of the Westinghouse W20 Series, which includes all Westinghouse 20V tools purchased after 2023. DeWalt 20V MAX and 20V MAX XR batteries also work
- PRECISION CUTTING AND A WIRE GUIDE: The 12 inch cutting swath is designed for good coverage and made to go where mowers and larger trimmers can't fit for more detailed trimming, while the foldable guide protects trees, plants, furniture and fences
