9 Best DeWalt String Trimmers (November 2026)

The best DeWalt cordless string trimmers include the WORX 20V 12" 2-in-1 Cordless String Trimmer for edging and trimming, the DEWALT QUICKFEED STRING TRIMMER HD for quick line replacement, and the DEWALT DEWALT-DWO1DT802-3/PACK DWO1DT802 String Trimmer Line for stocking replacement line.

1. The best DeWalt string trimmers for different yards
2. How to choose a DeWalt cordless string trimmer
3. Best DeWalt string trimmer verdict

The best DeWalt string trimmer for most 20V MAX users is the DCST922B, with a 14 in cutting width, folding hinge, variable speed and QuickLoad spool. That mix covers most yard work without forcing a heavier platform.

Choose the 60V FLEXVOLT model for a wider 15 in cut, or the 20V kit if you also need a leaf blower. The wider path cuts open areas faster, while the kit adds leaf clearing in one purchase.

We compared DeWalt cordless models by battery platform, cutting width, line size, storage and included equipment. Those factors shape how a tool feels, stores and keeps running, so they matter more than one headline spec.

WORX and HEINPRO options add alternatives for edging, weight and battery compatibility. They suit buyers who want guided edging, the lightest body, or use a DeWalt 20V MAX battery they already own.

For a first cordless trimmer, put platform fit ahead of cutting width. A lighter 20V tool is often easier to control around beds and fences, while 60V suits thick growth and large open areas.

New to this tool type? Our guide to what a weed trimmer is explains how string trimmers differ from edgers.

Trimming cleans grass where a mower cannot reach, while edging defines a cleaner line along paths and borders.

Check what is in the box before you buy. Some picks include a battery and charger, while bare tools assume you already own a matching battery.

Storage and line size separate the options too. A folding hinge helps in a small shed or garage, while most DeWalt models here use 0.080 in line and a few also accept 0.095 in for tougher growth.

Care starts with the guard in place and the head clear of packed grass. Set up the handle and guard before your first pass so the tool stays balanced and reduces arm strain.

Think about yard shape rather than chasing the biggest number. Open lawn, narrow beds, slopes and ornaments each favour a different swath and weight.

That is why the DCST922B leads for many 20V MAX users. Its 14 in swath, folding storage and speed control suit everyday yards, while heavier needs point to 60V and attachment capable models.

The best DeWalt string trimmers for different yards

The DCST922B is the best overall DeWalt 20V choice, while the DCST970X1S is better for a wider cut and the DCST925B keeps the setup straightforward. The right pick depends on battery platform, storage space and thick growth.

For a small yard with open grass and a few beds, a 20V model can be enough. For a larger yard with thick edges, the added width and power of a 60V model may save time.

For another cordless brand, compare EGO string trimmers. That helps if you are open to leaving the DeWalt battery system.

Our score weighs specs, features and buyer feedback against what you are shopping for. It guides fit, not a promise that one tool suits every yard.

Check battery fit first. A bare tool suits a current battery owner, while a kit is simpler for a buyer starting from scratch.

Cutting width comes next, then storage. A wider swath covers open ground faster, but a narrower one steers easier near plants, and a folding hinge suits tight spaces.

Line size, reload style and weight also affect daily use. QuickLoad saves time, manual winding suits advance staging, and weight matters over a full session.

Each section below explains who a model suits. Read the trade offs in that light before comparing prices or packages.

WORX 20V 12" 2-in-1 Cordless String Trimmer: Best for edging and trimming

9.7/10Our score

• 12 in cutting diameter
• 2-in-1 trimmer and edger
• 2 included 20V batteries
• 90-degree tilting head

The WORX WG163 combines trimming and edging with two included 20V Power Share batteries. Its wheels, tilting head and spacer guard suit users who want guided edging around lawn borders.

See it on Amazon

Pros

• 2-in-1 design
• 2 batteries and charger included
• Rubberized edging wheels

Cons

• Uses 0.065 in line
• Not part of the DeWalt battery system

The WORX WG163 stands out for buyers who want both trimming and edging in one tool. It converts from a string trimmer to an edger, and rubberized wheels help guide the edging cut along a lawn border.

For hand-powered lawn edging, see how to use a manual lawn edger.

The head tilts 90 degrees, which can help when you are working across sloped ground or reaching under obstacles. An adjustable spacer guard helps keep the line away from plants, landscape features and lawn ornaments.

The tool has a 12 in cutting diameter, 7600 rpm no-load speed and 5.5 lb machine weight. It uses 0.065 in line, so it belongs in a different line-size group from the DeWalt models that use 0.080 in or 0.095 in line.

Two 20V Power Share maxLithium batteries and a 20V charger are included. Those batteries work across the WORX 20V and 40V Power Share family, not the DeWalt battery platform.

Choose this pick if guided edging and a lighter tool matter most. If your priority is staying inside DeWalt's battery system, choose one of the DeWalt models below instead.

2

DEWALT QUICKFEED STRING TRIMMER HD: Best for quick line replacement

9.6/10Our score

• QuickLoad spool
• Pre-wound 0.080 in dual line
• Accepts DeWalt 0.095 in line
• 7000 rpm

This DeWalt replacement spool is for cordless trimming and edging. The twist-on QuickLoad design is useful when you want a faster reload than winding line by hand.

See it on Amazon

Pros

• Fast QuickLoad reload
• Pre-wound line
• Accepts 0.095 in line

Cons

• A replacement spool, not a complete trimmer
• Compatibility should be checked before ordering

The DEWALT QUICKFEED STRING TRIMMER HD is a replacement spool rather than a complete string trimmer. It suits DeWalt cordless trimmer owners who want pre-wound 0.080 in dual line and a twist-on reload method.

That design suits a buyer whose current spool is empty, cracked or tangled. A pre-wound spool gets you back to work without winding line by hand.

It also accepts DeWalt 0.095 in line where the trimmer supports it. The thicker line can suit tougher growth, while the standard diameter suits routine trimming.

The spool is compatible with DeWalt cordless string trimmers for trimming and edging. Compatibility still needs a model check because DeWalt uses more than one spool type.

Set up is simple, with a twist of the cap for reloading. Keep the spool dry, avoid crushing the cap, and replace a worn spool before the line breaks often.

Check your trimmer model and line requirements before ordering. For broader head choices, see the best DeWalt string trimmer replacement head and the best DeWalt string trimmer replacement spool.

Buy this spool when reload speed matters and your trimmer takes it. Buy a complete trimmer instead if you need a new tool, battery or charger.

3

DEWALT DEWALT-DWO1DT802-3/PACK DWO1DT802 String Trimmer Line: Best for stocking replacement line

9.4/10Our score

• 0.080 in line
• 3-pack
• 225 ft size
• Compatible with selected DeWalt models

The DWO1DT802-3PK gives you three packs of 0.080 in trimmer line. Its stated compatibility list includes several DCST920, DCST970 and DCST990 versions.

See it on Amazon

Pros

• Three-pack format
• 0.080 in line
• Genuine OEM replacement part

Cons

• Manual line replacement
• Compatibility varies by model type

The DWO1DT802-3PK is a 3-pack of 0.080 in DeWalt trimmer line, with each pack sized at 225 ft. It is a practical choice when you prefer to keep replacement line ready for several reloads.

For a line replacement walkthrough, see EGO trimmer line replacement.

Its compatibility list includes DCST920B Type 2 and Type 3, DCST920P1 Type 1 through Type 3, DCST970B Type 1, DCST970X1 Type 1, and selected DCST990 models. Match the type number carefully because the same base model can have different versions.

This is manual line, so it does not replace a complete spool assembly. If you own a supported model and want genuine OEM replacement line in bulk, the three-pack is the main reason to choose it.

Read our guide to DeWalt trimmer string replacement before winding new line. If you need a thicker-line comparison, see the best DeWalt .080 string trimmer line.

4

DEWALT 20V MAX String Trimmer and Leaf: Best for a 20V yard tool kit

9.1/10Our score

• 20V MAX string trimmer and leaf blower kit
• 13 in cutting width
• Battery and charger included
• DCST925 and DCBL722 combination

This kit pairs the DCST925 string trimmer with the DCBL722 leaf blower. It fits a buyer who wants trimming and leaf clearing in one 20V MAX package.

See it on Amazon

Pros

• Trimmer and blower together
• Battery included
• 13 in cutting width

Cons

• Less focused than a trimmer-only purchase
• Kit contents should match your needs

The DCKO215M1 combines a DEWALT DCST925 string trimmer and DCBL722 leaf blower in one kit. It fits a buyer who wants to trim grass and clear leaves without choosing two separate packages.

That pairing suits a home with both grass edges and leaf cover. You can trim first, then use the blower to clear cuttings from paths and beds.

The trimmer has a 13 in cutting width, and the kit includes 1 lithium-ion battery. The included components are the DW combo kit with DCST925 and DCBL722.

A 13 in swath is a middle ground for many yards. It covers open areas in a reasonable number of passes while staying manageable near borders.

In daily use, one battery has to cover two jobs. Plan the order so trimming comes first, then blowing, and keep the battery charged for the next session.

Fit the guard on the trimmer, check the line, and keep the blower tube clear before you start. Store the kit dry and check both heads for packed debris.

Battery planning matters with any cordless trimmer. Our guide to the best battery for a DeWalt weed eater covers platform fit, while how long cordless string trimmer batteries last explains runtime factors.

This kit is less focused than a trimmer only buy. It is worth it only if you will use both tools on a regular cycle.

5

DEWALT FLEXVOLT 60V MAX* String Trimmer: Best for wide heavy-growth cuts

8.9/10Our score

• 60V MAX FLEXVOLT platform
• 15 in cutting width
• Brushless motor
• Two speeds
• 3-Ah battery included

The DCST970X1S gives you the widest stated cutting width here at 15 in. Its 60V platform, brushless motor and two-speed design suit larger areas and tougher growth.

See it on Amazon

Pros

• Widest trimmer swath here
• 60V platform
• Battery included

Cons

• Heavier at 12 lb
• Uses the 60V FLEXVOLT platform

The DEWALT FLEXVOLT 60V MAX String Trimmer is the wide-cut choice in this group, with a 15 in cutting width and a 3-Ah battery included. Its brushless motor and two-speed design suit larger trimming areas and thicker growth.

For tougher overgrowth, compare string trimmers and brush cutters.

At 12 lb, it is heavier than the 20V DCST922B and HEINPRO models. That added weight is worth considering if you trim for long periods or need to carry the tool across a large property.

The DCST970X1S uses the 60V MAX FLEXVOLT platform. Its package is identified as a string trimmer kit with the battery included, so it is a more complete starting point than the bare-tool 60V DCST972B.

Choose it when the wider 15 in swath and included battery matter more than low weight. For a lighter 60V bare-tool option with attachments, compare the DCST972B below.

6

HEINPRO Cordless String Trimmer Compatible with Dewalt: Best for a light DeWalt-battery alternative

8.6/10Our score

• Compatible with DeWalt 20V MAX batteries
• 12 in cutting width
• 2-in-1 trimmer and wheeled edger
• 6 line spools included

The HEINPRO is a 4.2 lb alternative for users who already have a compatible DeWalt 20V MAX battery. It converts to a wheeled edger and includes 6 spools of 0.055 in line.

See it on Amazon

Pros

• Lightest complete trimmer body here
• 2-in-1 edging
• 6 spools included

Cons

• Battery and charger not included
• Third-party compatibility

The HEINPRO cordless string trimmer is a light alternative for users who already have a compatible DeWalt 20V MAX battery. The trimmer weighs 4.2 lb and has a 12 in cutting width.

That weight suits buyers who trim for longer stretches or carry the tool across steps and slopes. A lighter body can reduce fatigue, even if the swath is narrower.

It converts from a string trimmer to a wheeled edger by rotating the cutting head 90 degrees. The wheels then help guide a straighter line along a path or border.

The handle rotates 180 degrees, and the cutting angle has 5 positions for adjusting the tool to your height and terrain. That range helps taller users and anyone working on uneven ground.

The package includes 6 pre-wound spools of 0.055 in line. Having spares ready can keep a session going when a spool runs out.

Battery and charger are not included, so this option only makes sense if you already have a compatible battery and accept third-party compatibility. Check the battery fit before you order.

The dual-action line system releases about 0.5 in automatically when the trigger starts, and a button can release more line manually when needed. That gives more control than a basic auto feed when the line breaks short.

In use, the spacer guard helps protect plants while you work close to beds. Keep it fitted and adjust your stance rather than leaning the head into stems.

Care is straightforward. Wipe the head clean, store spare spools dry, and avoid hard strikes that waste thin line.

Choose it for low weight and edging flexibility rather than for a standard DeWalt-branded tool. It suits a small to mid sized yard where control matters more than maximum power.

7

DEWALT DCST972B String Trimmer: Best for attachment versatility

8.4/10Our score

• 60V MAX platform
• Universal attachment capability
• 15 to 17 in adjustable swath
• Variable trigger and high-low control

The DCST972B offers a 15 or 17 in adjustable swath and universal attachment capability. It is a bare tool, so battery and charger planning matters before you choose it.

See it on Amazon

Pros

• Adjustable 15 or 17 in swath
• Attachment capable
• Variable speed control

Cons

• Battery and charger not included
• 60V platform

The DCST972B is the best DeWalt choice here if you want a 60V trimmer with universal attachment capability. It accepts additional tool pieces and gives you a 15 or 17 in adjustable swath.

That flexibility suits a yard where trimming is only part of the work. An attachment capable shaft can grow with your needs, while the swath can be set wider for open grass.

The trimmer uses 0.080 in dual line and also works with DeWalt 0.095 in line. The thicker option can help in tougher growth, while the standard line suits routine cutting.

A variable trigger and high-low speed control let you choose between more power and longer runtime based on the work. Lower speed can help around delicate edges, while higher speed suits thicker patches.

This is a bare tool, and the package does not include a battery or charger. Battery planning is therefore part of the purchase, not an afterthought.

It weighs 9.6 lb, which is lighter than the 12 lb DCST970X1S but still more substantial than the 20V models. That weight is easier to accept in shorter bursts than in all day sessions.

Set up needs care with the guard and handle so the longer swath stays controlled. Keep your feet set and let the line do the work, rather than swinging the head.

Care includes cleaning the head, checking line length and storing the shaft where the attachment end stays straight. A dry store keeps the head and line in good shape.

Choose it if attachment flexibility matters and you already have the 60V MAX battery setup. If compact storage is more important, the folding DCST922B is a better match.

Dewalt DCST922B 20V MAX 14 in Cordless: Best for compact 20V storage

8.1/10Our score

• 14 in cutting width
• Folding hinge
• Variable-speed trigger
• QuickLoad spool
• High-low speed control

The DCST922B is the strongest fit for most 20V MAX users who want a full-size 14 in swath with easier storage. The folding hinge reduces the trimmer length by 40%.

See it on Amazon

Pros

• Folding storage design
• 14 in swath
• Guard and handle included

Cons

• Bare tool
• Battery and charger not included

The DCST922B is the best overall 20V MAX trimmer for compact storage, with a 14 in swath and a folding hinge that cuts trimmer length by 40%. It fits garages, sheds or vehicles where full-length storage is awkward.

The folding design suits buyers who carry tools in a car or store them upright. You can fold it down after use without needing a wall slot for a full shaft.

A variable-speed trigger and high-low switch manage power and runtime. Gentle control helps near plants, while higher speed helps in thick grass.

The QuickLoad spool uses 0.080 in line, with a stated 4600/6000 rpm range. QuickLoad speeds reloads when the spool runs out.

The package includes the trimmer, guard and handle. It is a bare tool, so plan for a compatible 20V MAX battery and charger.

That suits a current 20V MAX owner. A new buyer should add battery and charger cost to the comparison.

The 14 in swath is a practical middle width. It clears open areas faster than a 13 in model while staying controllable near borders.

Fit guard and handle, and lock the hinge fully straight before work. Keep the hinge free of debris and wipe the head after each session.

Choose it for storage, width and 20V access. For a smaller 13 in option without the folding hinge, consider the DCST925B.

9

Dewalt DCST925B 20V MAX Variable Speed Lithium-Ion: Best for a simple 20V trimmer

7.8/10Our score

• 13 in cutting swath
• 0.080 in line
• Variable-speed trigger
• High-low speed control
• Gear drive transmission

The DCST925B keeps the choice simple with a 13 in swath, 0.080 in line and variable speed. It suits buyers who already own a compatible battery and do not need a folding hinge.

See it on Amazon

Pros

• 13 in cutting width
• Variable speed
• High-low control

Cons

• Tool only
• No battery or charger details included

The DCST925B is a simple 20V MAX choice with a 13 in cutting swath, 0.080 in line and a variable-speed trigger. Its gear drive transmission is designed for cutting through overgrowth.

That design suits a buyer who wants a straightforward tool without extra features. The swath covers most home yards, while the gear drive helps in thicker patches.

High-low speed control gives a choice between added power and extended runtime. Higher speed suits dense grass, while lower speed can help with control and battery life.

The tool has a stated speed of 6300 rpm and is described as lightweight and ergonomic. Balance matters when you reach under shrubs or work along a fence.

This is a tool-only model. For corded and cordless alternatives, compare electric string trimmers.

That status suits a buyer who already owns a compatible 20V MAX battery. A new buyer should check whether a kit or a bare tool gives the better starting point.

In daily use, the 13 in width is easy to steer in tight spaces. Keep the guard fitted, clean the head after use, and avoid stones or fences that break line quickly.

Choose it without the DCST922B folding hinge or a wider 14 in swath. The DCST925 also appears in the DCKO215M1 kit if you need both tools with a battery included there.

How to choose a DeWalt cordless string trimmer

Choose the battery platform first, then compare cutting width, line size and whether the package includes a battery. A 20V MAX trimmer is usually the simpler match for an existing 20V yard-tool system, while a 60V MAX model suits wider swaths and heavier work.

If you prefer plug-in power, compare corded electric string trimmers.

Should you choose a DeWalt 20V MAX or 60V MAX trimmer?

Choose a 20V MAX DeWalt cordless string trimmer if you already own 20V batteries or want a lighter tool. The DCST922B weighs 7.3 lb and cuts a 14 in swath, while the DCST925B cuts 13 in.

Choose a 60V MAX model if you want a wider cutting area or attachment capability. The DCST970X1S has a 15 in swath and includes a 3-Ah battery, while the DCST972B adjusts from 15 to 17 in but is a bare tool.

Do not assume that every DeWalt battery fits every trimmer. Match the voltage platform and model requirements before you order.

Is a wider cutting width always better?

A wider cutting width can reduce passes across open grass, but it also needs more room around beds, fences and ornaments. The DCST972B offers the widest adjustable range here at 15 to 17 in, while the DCST922B provides a more compact 14 in option.

For tight borders, a 12 or 13 in trimmer can give you more control. The WORX WG163 also adds rubberized wheels and a tilting head for guided edging.

What line size should you use?

Use the line size approved for your exact trimmer and spool. The DeWalt models here commonly use 0.080 in line, while the QUICKFEED spool and DCST972B also work with 0.095 in line.

The HEINPRO uses 0.055 in pre-wound spools, and the WORX WG163 uses 0.065 in line. Line diameter is not interchangeable across every tool, so check the model instructions before replacing it.

Do you need a battery and charger?

You need to buy or already own a compatible battery and charger when the product is a bare tool. The DCST922B, DCST925B and DCST972B are the clearest examples in this group.

The WORX WG163 includes 2 20V Power Share batteries and a charger. The DCKO215M1 includes 1 lithium-ion battery, while the DCST970X1S includes a 3-Ah battery.

What maintenance does a cordless trimmer need?

Keep the cutting head clear, inspect the line before use and avoid striking fences, stones and hard surfaces. Abrasive obstacles can break line and make reloads more frequent.

Store the tool with the battery handled according to the battery maker's instructions. When the spool is empty, use the correct line diameter and follow the model-specific winding or QuickLoad process.

Best DeWalt string trimmer verdict

The DCST922B is the best DeWalt string trimmer for most 20V MAX yards because it combines a 14 in cut, variable speed and folding storage. That mix suits everyday trimming without a heavier platform.

Pick the DCST970X1S for a wider 15 in cut with a battery included, the DCST972B for attachment capability, or the DCST925B for a simpler 13 in tool. Each pick fits a different yard shape.

Large, open yards benefit from the wider 60V cut. Tight, detailed yards often suit a 13 or 14 in 20V tool for easier control.

For trimming and edging in one light package, compare HEINPRO with the WORX WG163. Both help with guided edging but sit outside the standard DeWalt range.

Check battery fit before you decide. A bare tool suits a current battery owner, while a kit is simpler when you need a battery and charger.

Check line size as well. Most DeWalt models here use 0.080 in line, while some also accept 0.095 in line.

Do not ignore storage. The folding hinge on the DCST922B makes a real difference in a small shed or vehicle boot.

Set the handle and guard before your first pass and keep the head clear as you work. After each session, clean the head, check line wear and store the tool dry.

For replacement care, start with best DeWalt string trimmer DCST922B parts or best DeWalt string trimmer DCST970 parts. Those guides help confirm part numbers before you order.

Match the final choice to your battery, yard and storage. That fit matters more than any single spec.

Frequently asked questions

What is the best DeWalt string trimmer for most yards?

The DeWalt DCST922B is the best fit for many 20V MAX users because it combines a 14 in swath, variable speed, high-low control and a folding hinge. Choose the 60V FLEXVOLT DCST970X1S when you want a wider 15 in cut and a battery is included.

What is the difference between a DeWalt 20V and 60V trimmer?

A DeWalt 20V MAX trimmer fits the 20V MAX battery platform, while a 60V MAX model uses the FLEXVOLT platform. The 60V options here offer wider cutting widths, but they can add weight and require different battery planning.

Can you use a DeWalt 20V battery in every DeWalt trimmer?

No. The trimmer must match the battery platform.

The DCST922B and DCST925B are 20V MAX models, while the DCST970X1S and DCST972B are 60V MAX models.

Check the exact model and battery requirements before buying.

What line size does a DeWalt string trimmer use?

The DeWalt trimmer models here commonly use 0.080 in line. Some models also work with 0.095 in line, including the QUICKFEED spool and DCST972B.

Always match the line to your trimmer model and spool.

Is the DeWalt DCST922B a bare tool?

Yes. The DCST922B package includes the 20V MAX string trimmer, guard and handle, but the product data does not include a battery or charger.

That makes it a better fit for an existing 20V MAX battery system.
