Replacement trimmer line for bump‑feed string trimmers. The line is made from flexible, impact‑resistant nylon with an aerodynamic profile. Pack contains 225 ft of 0.080 in (2.03 mm) line for trimming and edging grass. Intended for use with compatible single‑ and dual‑line bump‑feed heads; installs by winding onto the spool.
DeWalt 0.080 in. x 225 ft. replacement trimmer line (bump-feed) Review
Why I reached for this line
I swapped the tired string on my cordless trimmer for DeWalt’s 0.080-in line to see if a name-brand spool could make a noticeable difference in cut quality and runtime. I usually keep 0.095-in on hand for heavy growth, but for weekly lawn maintenance on battery trimmers, 0.080 often hits a sweet spot between cutting speed and efficiency. After several weeks of trimming, edging, and some less glamorous work along chain-link and concrete, this line proved both capable and fuss-free—with a few caveats to keep it performing at its best.
Loading and setup
The 225-foot roll is tidy and compact, and the high-visibility yellow/black color is genuinely useful for winding and for spotting the line end when it snaps back into tall grass. The line feeds cleanly from the coil without a bird’s nest, provided you pull it under light tension and keep the roll from spinning freely. I’ve found it easiest to pull from the center opening and pinch the coil as I go so it doesn’t unravel.
On my DeWalt bump-feed heads (DCST922 20V single line and DCST972 60V dual line), I loaded roughly 20 feet per refill—10 feet per side on the dual-line head. Wind in the direction of the arrows, keep consistent tension, and don’t overfill past the spool lip. Overfilling and loose wraps are the two fastest ways to cause self-feeding or jams. With even wraps, the line stayed put and fed predictably with a bump.
If you’re seeing the line creep out on its own, check three things:
- Direction: wind exactly as indicated on the spool.
- Tension: keep wraps snug; loose coils slip under centrifugal force.
- Capacity: stop just short of the spool rim and lock the ends in the retention notches before reassembling.
A quick tip: nylon line holds “coil memory,” especially in cool weather. If you find it a bit springy, a brief soak in warm water before loading helps it lay flatter on the spool.
Cut quality and speed
This line has an aerodynamic profile that feels smoother running than square or star-cut strings I’ve used. On the 20V trimmer, I noticed slightly less audible whine at higher RPM and a cleaner cut on turfgrass, particularly when edging sidewalks where round line can sometimes shred rather than slice. In light to medium grass and typical lawn weeds, it takes a clean bite and flicks the clippings away without bogging.
Where the 0.080 size shows its limits is in dense, woody stems and along abrasive surfaces. It will chew through tall, soft weeds just fine, but if your routine includes a lot of contact with concrete, brick, or chain-link, you’ll see the tips notch and shorten quickly. That’s expected for this diameter. For aggressive edging-only days or brushy fence lines, I still prefer stepping up to 0.095. But for weekly maintenance, the 0.080 delivers a tidy cut with less drag—exactly what I want on a battery platform.
Durability and wear
For a round 0.080, the longevity is good. The nylon feels dense and slightly resilient rather than brittle. It resists splintering at the tips better than bargain line, and I didn’t experience welding (where melted line fuses on the spool) as long as I bumped to advance before the ends got too short. If you push the line down to nubs and keep running max RPM in hot weather, any string can heat up and weld. Advance early, keep the guard line length, and you’ll avoid most issues.
Impact with hard edges still shortens it—no miracle there. The good news is that it tends to fray cleanly rather than shatter, so it continues to cut even as it wears. In cooler mornings, I noticed a bit more chipping on contact with stone; warming the line or soaking it briefly mitigated that.
Based on my consumption, a 20-foot refill lasts me two to three typical yard sessions on the 20V trimmer and one to two more demanding sessions on the 60V when I’m cutting faster and closer to obstacles. With 225 feet on the roll, that’s roughly 10–11 full refills, which stretches nicely through a season of regular use.
Feeding and bump performance
The line’s smooth jacket helps it slip inside the eyelets without grabbing, and it advances consistently with light taps. On both single- and dual-line heads, I rarely needed more than one bump to refresh the cutting diameter. If you find yourself bumping repeatedly, check for overfill (the most common cause) and make sure the spool springs are clean and not caked with dust. A quick wipe inside the head during refills pays off in trouble-free feeding.
I had one instance of minor self-feed on the dual-line head early on, which I traced to a loose first layer on the spool. After rewinding with firmer tension and leaving a small clearance under the rim, it didn’t recur.
Efficiency and runtime
This is where the line’s profile and diameter help most. On the 20V trimmer, I consistently finished my typical suburban yard with a bar or two more battery than with chunkier, more aggressive line. Less wind resistance means the motor doesn’t work as hard to spin the string up, and that’s noticeable by ear and in the battery gauge. The cut is still clean, so you aren’t trading performance for efficiency unless you’re trying to mow down stiff, woody stems. For routine grass work, it’s a smart pairing.
Compatibility notes
DeWalt lists compatibility with a broad range of its bump-feed heads, and I had zero fitment or feed issues on the DCST922 (single line) and DCST972 (dual line). If your head accepts 0.080 and you wind it per the marked direction, it behaves exactly as it should. The high-visibility color is more than cosmetic—it makes it easier to see how much line remains on the spool at a glance.
Where it shines
- Weekly lawn maintenance on battery trimmers, where reduced drag extends runtime
- Clean edging on concrete and pavers with less fray than some square lines
- Predictable bump-feed behavior when wound with steady tension
- Visibility while loading and during use
Where it falls short
- Extended contact with concrete, brick, or chain-link eats 0.080 quickly
- Cold-weather stiffness can increase chipping unless you pre-warm/soak the line
- Overfilling or loose winding can lead to self-feed; careful loading matters
Tips for best results
- Measure 20 feet per refill (10 feet per side on dual-line heads) and avoid overfilling.
- Wind firmly in the direction of the arrows; lock the ends before reassembly.
- Bump to advance before the line shrinks below the guard length to prevent welding.
- For lots of hard-surface edging or brushy fence lines, consider stepping up to 0.095 for that task.
- Store the roll indoors; if the line feels stiff, soak a refill length in warm water for 10–15 minutes before winding.
The bottom line
DeWalt’s 0.080 line hits the practical balance I want for battery-powered trimming: it cuts cleanly, feeds reliably, and helps stretch runtime without turning the job into a patience test. It’s not a miracle cure for concrete and chain-link—no 0.080 is—but in grass and typical lawn weeds it’s efficient, quiet, and durable for its size. The 225-foot roll goes a long way, the color makes handling easy, and loading is straightforward if you pay attention to winding direction and tension.
Recommendation: I recommend this line for homeowners and pros using 20V/60V DeWalt bump-feed trimmers who prioritize runtime and clean cuts in grass and light to medium weeds. If your work is heavy on abrasive edging or woody stems, keep a spool of 0.095 on the shelf for those days, but for weekly maintenance the DeWalt 0.080 is a dependable, efficient choice.
