DeWalt Trimmer Line, 0.080 in x 50 ft, Yellow Review

4.8 out of 5

Why I picked up this line

I spend a lot of time with cordless trimmers, and line choice can make or break both cut quality and runtime. I grabbed DeWalt’s 0.080 line in the 50-foot coil to see if its “aerodynamic” profile would actually translate to more cuts per charge and cleaner results around turf, beds, and fences. I ran it primarily on a DeWalt 20V MAX trimmer and also fed a few loads into a universal bump head on a gas unit to see how it behaved at higher RPM.

Setup and loading

The coil arrives neatly wound and easy to manage—no memory coils that spring into a rat’s nest as soon as you cut the tie. The line’s surface is slick rather than chalky, which helps during loading; it threads through eyelets without snagging and winds uniformly on the spool. I got two full reloads on a standard DeWalt bump head out of the 50-foot length, plus a short top-off.

A couple of setup notes that improved my results:
- Pre-cut equal lengths for dual-line heads so both sides advance evenly.
- Give the line a quick soak in water for 10–15 minutes before loading in hot, dry weather; nylon holds a bit of moisture and resists brittleness better that way.
- Check your head’s eyelets—if there’s a burr or a sharp wear line, any thin line will nick and break prematurely.

Cutting performance

In grass and typical lawn weeds, this line cuts cleanly and predictably. It’s a round, low-drag profile (DeWalt calls it aerodynamic), and you can feel that in how the trimmer spools up: less audible whistle, less strain, and slightly quicker recovery after bogging down in thicker patches. Edging along sidewalks at half throttle produced tidy lines without tearing the turf, and I didn’t see the “frayed whisker” ends that cheap round line can leave when it dulls.

On heavier weeds—think fibrous stems around 1/4 inch—the line still did fine as long as I fed it fresh and kept the head at a slight angle. It’s not a brush line, and if you’re routinely tackling woody stems or dried thistle, you’ll want to step up to 0.095 or a square/twisted profile. But for what most homeowners throw at a 0.080 setup, it’s right in the pocket.

Runtime and efficiency on cordless

This is where the line earns its keep. At the same cutting width I normally use, I consistently got a bit more runtime per battery compared to a generic square 0.080 and a budget round 0.080. It’s not night-and-day, but on a 5.0Ah pack I was able to finish the front and back trim and still have juice for touch-ups, where I’d normally swap batteries. Less drag means less current draw, and I could feel the motor run slightly cooler after a long stretch.

If you’re in the habit of running full trigger all the time, you’ll still benefit, but the savings are most noticeable when you modulate speed. On lower speed settings, this line holds momentum well enough that you don’t feel like you’re giving anything up.

Durability and break resistance

For a round 0.080, durability is respectable. I intentionally worked along chain-link fence, brick edging, and rough concrete to see how it would fare. Abrasive contact eats 0.080 line no matter the brand, but I found I could bump-feed at normal intervals rather than constantly re-feeding. The nylon blend DeWalt uses has a bit of “give” when it snaps—you get a clean break without a stringy unravel.

I did have one early break inside the head after smacking a fence staple at full tilt. That’s not a typical occurrence for me, but it’s a reminder that thin line is sensitive to sudden shock when the head is spooled tight. After reloading and paying more attention at fences, I didn’t repeat the issue. If you routinely trim hard against metal or stone, consider a thicker diameter or a more abrasion-oriented profile.

What I didn’t experience:
- Line welding on the spool, even after extended high-speed runs in warm weather.
- Kinking or flat spots after sitting; the coil’s memory is minimal.
- Splitting or delamination at the ends when it wears down.

Feed and bump behavior

Advance was smooth and predictable. The line feeds cleanly on DeWalt’s bump head and on an aftermarket universal head. Because it’s a slick-surface round line, it doesn’t dig into itself when packed tight, so you get a consistent bump every time without needing to slam the head on the ground.

One tip: if you overfill the spool, any line can bind when it heats up. Stick to the capacity marks. With 0.080 you’ll be tempted to cram in “just a bit more”—don’t.

Noise and feel

Round, low-drag line does reduce the whistle at higher RPM. It’s not silent, but on the cordless trimmer I could hold a conversation a little more easily without raising my voice. The head feels light and responsive; there’s less rotational inertia than heavier lines, which makes finesse work around delicate beds easier.

Compatibility

  • Works in any head rated for 0.080 line, including most DeWalt 20V/60V trimmers and common universal bump heads.
  • If your trimmer supports both 0.080 and 0.095, you’ll gain runtime with this line but give up some durability in abrasive contact.

Color is a bright yellow that’s easy to see when you’re trimming close to edging stones or mulch—handy for keeping from chewing where you shouldn’t.

Value and who it’s for

At 50 feet, this coil is a convenient size for a couple of reloads or for keeping in a carry bag. Price per foot won’t match bulk spools, but if you’re testing line or only trimming a yard or two, the small coil makes sense. For pros or large properties, you’ll want a larger spool of the same material.

This 0.080 line is best suited to:
- Homeowners prioritizing runtime and smooth feeding on cordless trimmers.
- Regular lawn maintenance: turf edging, light-to-moderate weeds, detail work around beds and hardscape.
- Users who dislike fiddly line feeds and want consistent bump performance.

If your work involves a lot of chain-link fencing, rough concrete, or thick, woody weeds, a heavier 0.095 or a square/twisted profile will last longer between bumps, even if it costs you some runtime.

Tips for better results

  • Let the line do the work. Keep the head at a slight angle and use the tip for cutting rather than pushing the head into material.
  • Keep the guard and knife sharp and intact so the line trims to proper length; overlong line will break more easily and drain batteries.
  • Avoid holding the line against metal fencing—skim along it instead.
  • Store the coil in a cool place; a quick water soak before loading helps in hot, dry conditions.

Pros

  • Noticeably efficient on cordless trimmers; modest runtime gains
  • Smooth, reliable bump-feed with minimal spool binding
  • Clean cuts in turf and typical lawn weeds
  • Bright, easy-to-see color aids precision
  • Good coil management; low memory

Cons

  • 0.080 diameter is vulnerable to premature wear against metal and rough concrete
  • Small 50-foot coil goes fast if you trim frequently
  • Not as crisp as square line for perfectly sharp edging in thick, wet grass

Recommendation

I recommend this DeWalt 0.080 line for homeowners and light-duty users who value smooth feeding and longer runtime on cordless trimmers. It keeps a trimmer feeling lively, trims grass and common weeds cleanly, and advances consistently without the headaches of spool welds or kinks. If your routine includes frequent contact with fences and masonry or you’re tackling heavier, woody growth, step up to a thicker or more abrasion-focused line. Otherwise, this is a smart, hassle-free choice that plays to the strengths of a cordless setup.
