Best Brush Cutter Attachments for Weed Eaters
As an Amazon Associate we earn from qualifying purchases.
A brush cutter attachment for weedeater is a metal blade that mounts on the straight shaft of a trimmer in place of the string head, so the trimmer can cut woody stems and heavy growth. The first check is the fit: most of the listings here name a 1-inch (25.4 mm) center hole or a 20 mm arbor, and they say the blade fits straight shaft trimmers only. This comparison covers six brush cutter attachments from their listings, with the fitting, blade type and brand compatibility each one states.
Quick answer
- Check the arbor first. The listings here name a 1-inch (25.4 mm) center hole, and some also fit a 20 mm arbor with a bushing.
- Choose a 3-tooth blade for light brush and saplings, a chainsaw-tooth blade for woody stems, and a carbide-tipped blade for hard wood and dense brush, as the listings describe them.
- Use a straight shaft trimmer. Several listings state straight shaft only, and that excludes many curved-shaft models.
- The Boxurn attachment is for a power head coupler, not a standard arbor. Confirm the coupling before you order it.
What a brush cutter attachment does
A string head holds a line that cuts grass and light weeds. A brush cutter blade is a solid steel or carbide blade that spins at the same speed and cuts stems the line cannot. The listings describe the job as clearing overgrown brush, thick stalky vegetation, small branches and saplings up to about an inch thick. The blade type decides how much of that work the attachment handles.
Three blade types appear in this group. A 3-tooth or 2-tooth tapered steel blade suits thick weeds and brambles. A chainsaw-tooth blade, sometimes called a round chainsaw tooth blade, cuts woody stems and small branches. A carbide-tipped blade lasts longer on hard wood and dense brush. Several listings include two blade types in one package, so you can switch between them on the same trimmer.

The six attachments, one by one
QLOUNI brush cutter blade set
The QLOUNI listing is a three-blade package: a 10-inch 80-tooth brush cutter blade, a 9-inch 20-tooth chainsaw tooth blade and a 9-inch 36-tooth carbide tipped blade. The center hole is 1 inch (25.4 mm), and the bullets say the blades suit most gas or electric trimmers, straight shaft only. The package includes a universal adapter set with thrust washers, rider plates, collar nuts, a locknut, two fixed plates and wrenches. The listing says two sets of adapters cover most trimmers, and it warns you to confirm the blade suits your model before you buy. The bullets list the chainsaw tooth blades as carbon steel and rust resistant. The listing gives brand examples: Husqvarna, Stihl, Oregon, Honda and Hitachi.
The set suits a homeowner who wants several blade types in one order. Check the adapter fit against your trimmer’s shaft before you assemble the blade.
Gashwer weedeater brush cutter blade with adapter kit
The Gashwer package holds two blades: a 9-inch 20-tooth carbon steel chainsaw tooth blade and a 9-inch 36-tooth carbide tipped blade. The bullets say the 20-tooth blade suits soft wood, saplings and small branches, and the 36-tooth blade suits hard wood and dense brush. The listing describes manganese steel for the body and reinforced carbide teeth. It includes two sets of mounting hardware with thrust washers, rider plates, collar nuts, a lock nut and wrenches, and it says gloves are included. The center hole is 1 inch (25.4 mm), and the listing names Husqvarna, Stihl, Ego, Oregon and Hitachi as compatible brands. The listing gives a 1-year warranty.
This is a good match for a trimmer owner who wants both a chainsaw tooth and a carbide tooth blade with a warranty term stated. Check the adapter kit against your trimmer’s gear case before you install it.
FORESTER 12 inch brush cutter blade
The FORESTER blade is a single 12-inch tapered steel blade with two teeth. The listing measures it at 12 inches high and 1 5/8 inches wide, with a 1-inch arbor. It includes a bushing so the blade fits a 20 mm arbor as well. The bullets say the blade fits a wide range of straight shaft weedeaters and trimmers, and they describe the blade as made of 4 mm hardened steel. The listing gives a Hi-Vis red finish, which the seller says helps you see the blade in thick vegetation. The listing does not give a warranty term or a list of brands.
The FORESTER blade fits the widest arbor range in this group, which makes it a good choice when you are not sure of your trimmer’s arbor size. Note that it is a single blade, not a set.
FUSIHWA 3-piece 10 inch brush cutter blade
The FUSIHWA package holds three 10-inch carbon steel blades with three teeth each. It fits a 25.4 mm or 20 mm arbor, and the listing names Stihl, Husqvarna, Ego, Echo, Makita, Dewalt, Ryobi, Hitachi and Oregon as compatible brands. One note matters before you buy: the title gives the blade thickness as 2.5 mm, while the bullets give 1.8 mm. The listing does not reconcile the two. Ask the seller which figure is correct, since blade thickness affects how the blade handles stems. The listing does not give a warranty term.
This is a three-pack for a homeowner who expects to replace blades over a season, and the two arbor sizes make it easy to fit.
ChoirLingo SK5 steel brush cutter blade, set of 2
The ChoirLingo listing is a two-blade set of SK5 steel blades, described as reversible and easy to resharpen. The item highlight says the blade cuts thick brush and small saplings. The bullets say the SK5 steel is harder than most standard blades, and that the blades can be swapped quickly when they get dull. The listing names Husqvarna, Stihl, Oregon and Hitachi as compatible brands. The listing gives a 2 mm thickness, a 12.01 by 3.54 inch size and a traditional style, but it does not state the arbor size, the cutting diameter or a warranty. Check the arbor before you buy, since that is the main fitting question this listing leaves open.
Boxurn 8 inch brush cutter attachment
The Boxurn attachment is a different design from the other five. The listing describes a complete attachment with an 8-inch cutting width, a three-tooth steel TRI-ARC blade, a front handle, a wrench and a hanger cap. Its drive connector is a square female shaft, and the listing says the power head coupler takes a 1-inch aluminum tube. That is a power head coupling, a different fitting from the 1-inch center hole of the blades, so check it against your trimmer before you assume it fits. The listing names power heads from Ryobi, Greenworks, Remington, Craftsman, Troy-Bilt, Snapper, Murray and Kobalt, and says it fits most other major brands. It does not name any weed eater model.
Choose this attachment only if your trimmer is a power head system with this coupling. Otherwise, pick one of the blades above that matches a straight shaft arbor. The listing does not give a warranty term.
How to choose the right blade
Begin with the trimmer’s shaft. Look for a straight shaft with a 1-inch (25.4 mm) center hole or a 20 mm arbor. Most of the blade listings here state that fit, and several say they are for straight shaft trimmers only. If your trimmer has a curved shaft, the straight shaft blades in this group are not the right type.
Then pick the blade type to match the growth. The QLOUNI and Gashwer sets include a chainsaw tooth blade for woody stems, and the Gashwer and QLOUNI sets include a carbide tipped blade for hard wood. The FORESTER and FUSIHWA blades are tapered or three-tooth steel, which suits thick weeds and brambles. The ChoirLingo set is a steel blade that the listing describes as suitable for thick brush and small saplings. Match the blade to the material you cut most often.
Last, count the blades. The QLOUNI set holds three blades, FUSIHWA holds three, Gashwer holds two, ChoirLingo holds two, and FORESTER holds one. A larger count is useful when a blade is lost or dulled during a season. Replacement blades are a common need, so the count matters more than it first appears.
Fitting and safety notes
Attach the blade only with the trimmer switched off and the battery or cord disconnected, and follow the manual’s steps for the adapter. The QLOUNI and Gashwer listings both include adapter kits with washers, collar nuts and wrenches. The FORESTER listing includes a bushing for the 20 mm arbor. Make sure the blade sits square and the nut is tight before you start the engine.
Wear eye protection, sturdy boots and long pants. The QLOUNI listing says to avoid hitting stones or hard objects with the blade and to wear ankle-high shoes, jeans and safety glasses. Those precautions apply to every blade in this group, since brush cutter blades throw debris. Keep bystanders and pets clear of the cutting area.
Blade speed and cutting ability depend on the trimmer’s power, which the listings do not describe in detail. A small trimmer with a light motor may bog down on thick stems even with a good blade, so match the blade to the trimmer’s rating in its manual.
Mistakes to avoid
- Ordering a blade without checking the arbor. The 1-inch center hole and the 20 mm arbor are different sizes.
- Buying the Boxurn attachment for a standard straight shaft trimmer. Its listing describes a power head coupler.
- Using a chainsaw tooth blade on stones or hard ground. The QLOUNI listing warns against it, and the same risk applies to every blade here.
- Overlooking the FUSIHWA thickness conflict. The title and the bullets give different figures.
- Assuming all blades fit all trimmers. The QLOUNI listing says the blade must suit your model.
Other attachments not in this comparison
An EGO brush cutter attachment, model BCA1220, appears in the same group of listings. It is excluded here because its listing says it works only with the EGO POWER+ Multi-Head System power head, not with a weed eater. Several wire-head trimmer attachments also appear in the group, but they are trimmer heads, not brush cutter blades, so they fall outside this comparison.
FAQ
Will a brush cutter blade fit any weed eater?
No. The listings here name a 1-inch (25.4 mm) center hole or a 20 mm arbor, and several say they are for straight shaft trimmers only. Measure your trimmer’s shaft and check the manual before you order. The Boxurn attachment uses a different coupling.
Which blade is best for saplings?
The QLOUNI and Gashwer listings describe a 20-tooth chainsaw tooth blade as suited to soft wood, saplings and small branches. The ChoirLingo listing says its steel blade is suited to small saplings. Choose the chainsaw tooth type for woody stems, and keep the blade’s size and arbor in mind.
What is the difference between a carbide tipped blade and a steel blade?
The Gashwer and QLOUNI listings describe carbide tipped teeth for hard wood and dense brush, and the Gashwer listing says the carbide teeth add wear resistance. The steel blades in this group are described as carbon steel or SK5 steel. The listings do not give a durability comparison, so use the blade description that matches your work.
Does any of these include a warranty?
The Gashwer listing gives a 1-year warranty. The other listings in this group do not state a warranty term, so ask the seller before you buy.
How many blades should I buy?
That depends on how much brush you clear. The QLOUNI and FUSIHWA sets each hold three blades, the Gashwer and ChoirLingo sets each hold two, and the FORESTER blade is a single unit. For a season of regular clearing, a set gives you a spare.

Bottom line
Pick a straight shaft blade that matches your trimmer’s arbor, choose a tooth type for the growth you cut most, and buy a set if you expect to replace blades. The QLOUNI and Gashwer sets cover chainsaw tooth and carbide tipped blades, the FORESTER blade fits the widest arbor range, and the Boxurn attachment is only for a power head coupling. Confirm the fit before you order any of them.
