Key Features
Overview
The DEWALT DWOAS4ED Edger Attachment is an edger attachment designed for cutting clean, controlled edges along grass lines, sidewalks, driveways, and landscape beds. Model Number: DWOAS4ED. If you already run a DEWALT attachment-capable power head and want a sharper finish than a string trimmer can give you, this is the add-on that handles that job.
What matters here is the cutting setup. DEWALT uses a 7-1/2 inch hardened steel blade, which gives you a real edging cut instead of a rough trim. The blade depth adjusts up to 2-1/2 inches, so you can go from light cleanup passes to deeper edge definition when a walkway or curb line has grown in over time.
This attachment is built to make edging easier to control over a longer pass. The large guide wheel helps the head track along hard surfaces with less drag, which matters when you are trying to keep a consistent edge without digging around. DEWALT also calls out the angled head, and that is a practical feature because it opens up your view of the cut line so you can stay on the edge you want.
In day-to-day use, that means cleaner results around asphalt, concrete, and bed lines with less guesswork. Instead of rolling the whole tool around trying to see where the string is hitting, you get a more direct sightline to the blade and edge path. For contractors maintaining properties or homeowners who care about curb appeal, that translates into faster touch-ups and a more finished look.
The DEWALT DWOAS4ED Edger Attachment is part of DEWALT's attachment-capable outdoor system. DEWALT positions it as a universal attachment for an attachment-capable power head, specifically the DEWALT DCST972 and DCED472 models. If you are already on that platform, this attachment is a lot more practical than storing a separate dedicated edger.
Build-wise, the key materials are straightforward and job focused. The blade is steel, the edge assembly is guarded, and the format is meant to take repeated contact along pavement and turf transitions. This is not a decorative accessory. It is a working attachment made for the part of lawn maintenance where a weak setup usually shows up fast.
Who should buy it? Anyone using a DEWALT attachment-capable outdoor power head who wants cleaner property lines with less fuss. It makes the most sense for landscapers, maintenance crews, general property upkeep, and homeowners who already own the compatible power head and want one system to handle trimming and edging.
Cut a Real Lawn Edge
This attachment is built for the part of the job a string trimmer never does quite as cleanly. The steel blade cuts a defined line where turf meets hardscape, giving walks and drives a sharper, more finished edge.
- 7-1/2 inch hardened steel blade for true edging work
- Adjustable cutting depth up to 2-1/2 inches
Track the Line More Easily
Edging gets frustrating when the tool wanders or you cannot clearly see the cut. The large guide wheel helps the attachment roll along the edge, and the angled head gives you a clearer view of where the blade is working.
- Large guide wheel supports smoother movement while edging
- Angled head improves visibility along the cut path
Add Edging Without Another Full Tool
If you already own a DEWALT attachment-capable power head, this add-on is the simple way to expand what that system can do. You get dedicated edging performance without taking up space with a separate standalone edger.
- Designed as an attachment for DEWALT attachment-capable outdoor systems
- Good fit for routine sidewalk, driveway, and bed-line maintenance
Built Around Practical Control
The layout is simple for a reason. A long shaft keeps the cutting head out front, while the guarded blade and wheel assembly are set up to make edge work more controlled and repeatable over longer runs.
- Guarded blade assembly suited for edging near hard surfaces
- Steel construction where it counts for repeated outdoor use

Pro Tip
When you are freshening up an overgrown edge, start with a shallower setting and make a second pass if needed. The adjustable depth lets you clean up the line without forcing the blade to chew out too much material at once.

- Who it's for: Landscapers, maintenance crews, and homeowners who want crisp edges along pavement and beds without buying a separate dedicated edger.
- Why it stands out: The hardened steel blade, 2-1/2 inch depth adjustment, guide wheel, and angled head all work toward one thing: cleaner edges with better control.
