Dewalt String Trimmer

DeWalt String Trimmers: Cordless Power Without Compromise

When it comes to cordless outdoor power equipment, DeWalt has built a reputation that extends well beyond the tool belt. Their lineup of string trimmers brings the same engineering rigor found in their professional-grade power tools directly to lawn and landscape maintenance — and the result is a family of trimmers that genuinely bridges the gap between homeowner convenience and contractor-level capability.

Two Battery Platforms, One Ecosystem

DeWalt's string trimmer range is organized around two core battery platforms, giving users the flexibility to match power output to the task at hand. The 20V MAX series — including popular models like the DCST920 and DCST922 — targets residential users who need a lightweight, maneuverable trimmer for routine lawn upkeep. The 20V MAX 14-inch folding string trimmer features an innovative folding hinge mechanism that reduces the length by 40% for accessible storage and quick portability. The QuickLoad™ Spool allows for fast and easy line replacement of 0.080-inch line with a 14-inch swath.

At the top of the range sits the FLEXVOLT 60V MAX platform, anchored by the DCST970 and DCST972 models. The 60V MAX string trimmer is designed to power through tough overgrowth and withstand everyday heavy-duty usage, featuring a high-efficiency brushless motor that maximizes runtime and motor life, and a lightweight, ergonomic design that maximizes control and minimizes stress on your arms. Featuring patented technology that changes voltage when you change tools, FLEXVOLT 20V/60V MAX batteries are compatible with 60V MAX and 300+ 20V MAX system tools. That kind of cross-compatibility means a battery purchased for a string trimmer does double duty across a massive range of DeWalt cordless tools.

Gear Drive and Brushless Motor Technology

What separates DeWalt trimmers from lighter-duty options is the engineering under the hood. The flagship FLEXVOLT models use a Gear Drive™ design specifically engineered to push through thick grass and dense overgrowth that would bog down a direct-drive motor. The Gear Drive design powers through tough overgrowth while a high-efficiency brushless motor maximizes run time and motor life. The variable speed trigger offers precise power control, as well as performance and runtime management with a Hi/Lo speed control switch. That Hi/Lo flexibility lets operators dial in the right balance of cut aggressiveness and battery longevity for any given section of the yard.

Cutting Swath and Line Compatibility

DeWalt offers a range of cutting widths across its trimmer lineup to suit different yard sizes and conditions. The 15-inch cutting swath accepts 0.080-inch line standard and also accommodates 0.095-inch line for heavier trimming applications. For users with the largest lots or most demanding clearing jobs, the DCST972 steps up to a flexible 15-inch to 17-inch adjustable swath with 0.080-inch dual line, and also works with 0.095-inch line. The bump feed head with DeWalt's QuickLoad spool design keeps line management simple, reducing downtime when it comes time to reload.

Built for the Long Haul

DeWalt backs its tools with a 3-year limited warranty, 1 year of free service, and a 90-day satisfaction guarantee — a confidence-inspiring package for anyone investing in a professional-caliber outdoor tool. Whether you're maintaining a suburban lawn or tackling a large commercial property, DeWalt's string trimmer lineup offers a model scaled to the job.
