The DeWalt DCST922B is a 20V string trimmer for buyers who want a folding tool that’s easier to store and transport. It has a 14-inch cutting width, uses 0.080-inch line and comes without a battery or charger.
The folding hinge is its clearest advantage over a standard long-shaft trimmer. Its tool-only setup makes the most sense if you already use DeWalt 20V MAX batteries.
What stands out in this DeWalt string trimmer 20V review?
The DCST922B’s folding hinge, 14-inch swath and variable-speed controls are its main decision points. These features make it worth considering if storage space matters and you want to adjust power while trimming.
DeWalt DCST922B 20V Folding Trimmer (Tool Only): Best for compact storage
- 14-inch cutting width
- Folding hinge reduces length by 40%
- Variable-speed trigger
- Hi/Lo speed control
A 20V MAX tool-only trimmer with a folding hinge for storage and transport. It uses 0.080-inch line and offers variable-speed control with a Hi/Lo switch.
Pros
- Folding hinge reduces length by 40%
- 14-inch cutting width
- Variable-speed trigger and Hi/Lo switch
- QuickLoad Spool
Cons
- Battery and charger are not included
- Uses 0.080-inch line
The trimmer includes a guard and handle. DeWalt describes the hinge as reducing the tool’s length by 40%, which can help when fitting it into a crowded garage or loading it for transport.
Who is the DeWalt DCST922B best for?
It fits homeowners who already have compatible DeWalt batteries and want a cordless trimmer that folds. The 14-inch cutting width also suits routine edging and grass trimming where a larger swath isn’t the priority.
It’s a weaker fit if you need a complete kit or want to cut a wider strip with each pass. The CRAFTSMAN option below includes a battery and charger, while Milwaukee offers a 16-inch cutting width.
How does the folding hinge affect storage?
The folding hinge reduces the DCST922B’s length by 40%, according to DeWalt’s product description. That feature can make storage and transport more convenient than a trimmer with a fixed shaft.
Measure the spot where you plan to keep it, including room to handle the folded tool. Also check how you’ll store its battery and charger, since those aren’t included.
If you’re comparing overall size and handling, our guide to how much a string trimmer weighs explains what tool weight can mean for carrying and storage. The DeWalt is listed at 7.32 lb without a battery, so the battery adds weight during use.
Are the cutting width and line a good match for your yard?
The DCST922B cuts a 14-inch swath with 0.080-inch line. That combination gives you a straightforward size to compare with a narrower adjustable head or a wider cutting path.
A 14-inch width may suit regular lawn edges, fence lines and small areas of grass. For a large yard, the wider Milwaukee model may reduce the number of passes, while the 13-inch CRAFTSMAN can adjust down to 11 inches.
Line diameter affects replacement choices. Read what size trimmer line to use before buying spools, and stick to the stated 0.080-inch size for this DeWalt.
What do the speed controls do?
The variable-speed trigger and Hi/Lo switch let you adjust power for the trimming task. DeWalt describes these controls as a way to manage performance and runtime.
The tool description gives two speeds, 4,600 and 6,000 RPM. A lower setting can be useful when you don’t need the higher speed, while the trigger lets you control output as you work.
Those controls don’t tell you exactly how long a battery will last in your yard. Runtime depends on the battery and how you use the trimmer, so check how long a weed eater battery takes to charge if you’re planning work around charging time.
What should you know about batteries and setup?
The DCST922B is a bare tool, so make sure you have a compatible battery and charger before choosing it. DeWalt describes the 20V MAX system as including more than 250 tools, and says FLEXVOLT batteries can power 20V MAX tools longer.
That system compatibility can simplify your choice if you already own DeWalt 20V MAX gear. If you’re starting from scratch, compare the cost and convenience of a kit that includes its battery and charger.
Check the guard and handle setup instructions before your first use. Keep the guard in place and use eye and hearing protection appropriate to the task and your surroundings.
How does the DeWalt compare with Milwaukee and CRAFTSMAN?
The DeWalt is the folding-storage pick, Milwaukee gives you a wider cutting path, and CRAFTSMAN includes a battery and charger. Choose by the feature that matters most for your yard and current battery system.

Frequently asked questions
Does the DeWalt DCST922B come with a battery and charger?
No. The DCST922B is a tool-only model, and its listed contents are the trimmer, guard and handle.
Plan for a compatible 20V MAX battery and charger if you don’t already own them.
Check your current battery system before buying so you know what else you’ll need.
How wide does the DeWalt DCST922B cut?
The DCST922B has a 14-inch cutting width and uses 0.080-inch line. That width gives you a middle ground between a smaller trim path and the 16-inch Milwaukee alternative here.
Your pace and the shape of your yard also affect how much ground you cover.
Does the DeWalt DCST922B fold for storage?
Yes. Its folding hinge reduces the trimmer’s length by 40% for storage and transport.
Consider where you’ll keep it and measure that space before buying; the folding feature can make a long tool easier to fit, but it doesn’t remove the need to store the battery and line safely.
What line does the DeWalt DCST922B use?
The DCST922B uses 0.080-inch line with its QuickLoad Spool and bump-feed system. Keep replacement line at that diameter, and follow DeWalt’s instructions when loading it.
If line compatibility is a key part of your choice, compare the stated line sizes before you buy.
