The DeWalt DCST972B FlexVOLT 60V MAX 17-Inch Brushless Attachment Capable String Trimmer (Tool Only) with Edger Attachment and Trimmer Line is built for users who want cordless outdoor power with room to expand. This is a string trimmer designed for trimming grass, clearing overgrowth, and handling edging tasks when paired with the included attachment. Model Number: DCST972B-DWOAS4ED-DWO1DT801. If you already run on the DEWALT outdoor platform or want one power head that can do more than one job, this kit makes a lot of sense.

The core of the setup is the DCST972B string trimmer, which uses a high-efficiency brushless motor to maximize runtime and product life while keeping enough cutting power on tap for heavier grass and rougher property maintenance. The adjustable 15 inch to 17 inch swath gives you some flexibility depending on whether you want faster coverage or a little more control in tighter areas. DEWALT also includes a dual 0.080 inch line setup, and the head also works with DEWALT 0.095 inch line if you want a heavier line option.

From a day-to-day use standpoint, the quick-load spool matters more than it sounds on paper. Re-spooling a trimmer can be a pain if the design is fussy. A quick-load system cuts down downtime when the line runs out, especially if you are maintaining larger properties or hitting stone edges, chain link, and dense weeds that wear line faster. Variable trigger control and hi/lo speed settings also let you balance power against runtime instead of running flat-out all the time.

What separates this model from a basic cordless weed trimmer is the attachment-capable design. DEWALT built this power head to accept additional universal attachments, which means it can be part of a broader outdoor setup rather than a single-purpose tool. In this package, that flexibility shows up right away with the included DWOAS4ED edger attachment. It converts the unit from trimming duty to defined edge work without needing a separate edger taking up trailer or garage space.

The included edger attachment is not an afterthought. It uses a 7-1/2 inch hardened steel blade with adjustable depth up to 2-1/2 inches, so you can cut a cleaner edge along sidewalks, driveways, and beds. The large guide wheel helps keep the cut steady, and the angled head gives you a clearer line of sight while you work. That is useful when you are trying to follow an existing edge cleanly instead of guessing where the blade is riding.

This package also includes a 50-foot spool of DEWALT DWO1DT801 0.080 inch trimmer line. DEWALT calls out its aerodynamic profile for cordless cutting efficiency and a material blend designed to stay flexible while resisting impact. In plain terms, it is made for the kind of trimming and edging work this combo is built to do, so you are not starting from zero when the prewound spool needs a refill.

For compatibility, the DCST972B is part of the DEWALT FlexVOLT 60V MAX system, and this listing is clearly a tool-only package. That means the battery and charger are not included here. If you already own compatible DEWALT 60V MAX batteries, this is an easy add. If you do not, factor that into the buy before checkout.

This is a good fit for homeowners with larger yards, property maintenance crews, landscapers, and contractors who need cordless trimming and edging without stepping down too far in power. It is also a smart choice for buyers who like platform tools and want the option to add more attachment-based outdoor tools later. If you just need a light trimmer for occasional touch-up work, it may be more machine than you need. If you want one cordless power head that can earn its keep in multiple roles, this setup is the better play.
