Best Brush Cutter Blades for Weed Eater Trimmers
As an Amazon Associate we earn from qualifying purchases.
Brush cutter blades for weed eaters are metal blades that replace the string head on a straight-shaft trimmer, so the machine can cut brush, saplings and thick weeds. This roundup covers six blade sets from our product pack, with diameters from 9 to 10 inches and tooth counts from 3 to 80. Each entry uses only what its listing states about size, tooth count, material, arbor fit and adapter kit. Where a listing does not give a point, the text says so, and where a listing’s own size fields disagree, the guide says that too.
Quick answer
- For clearing brush and small woody stems, the 9-inch 36-tooth carbide blades in this pack are the most common choice in the listings.
- For a light cutting job on grass and weeds, the 10-inch 3-tooth carbon steel blades are the listings’ simpler option.
- Check the arbor size and the adapter kit before buying. The listings give 1-inch (25.4 mm) and 20 mm arbors, and the adapter kit is brand specific.
- The listings say these blades fit straight-shaft trimmers. A curved-shaft trimmer needs a different accessory.
How to choose a brush cutter blade
Start with the material. The pack lists three types. Carbon steel and manganese steel blades are the lower-cost option, and the listings describe them as suited to grass, weeds and light brush. Carbide-tipped blades have hard tips on the teeth, and the listings describe them as suited to heavier brush and to a longer working life. A blade with 80 teeth gives a finer cut than a blade with 3 teeth, and the listings give tooth counts for each set.
Next, check the diameter. The listings give 9 inches and 10 inches for most blades in this roundup. A larger diameter covers more ground per pass but puts more load on the trimmer shaft. Some listings also give a 5-inch or 12-inch size in their spec fields, and those fields do not always match the title, so check the product page before ordering.
Then check the arbor and the adapter kit. The listings give a 1-inch (25.4 mm) center hole for most straight-shaft trimmers and a 20 mm option for some. Each kit includes thrust washers, a rider plate and a collar nut. The adapter that fits your trimmer’s gear case is the part that must match, so read the compatibility line in each listing.

Roundup: six blade sets from the pack
vidica 10 inch carbon steel brush cutter blades, 2-pack
This pack has two carbon steel blades with three teeth each. The title gives a 10-inch size, but the listing’s spec fields give a 5-inch size and an M10 by 1.25 thread. The listing says the blades fit most straight-shaft trimmers with a 1-inch arbor or a 20 mm arbor, and that an adapter kit is included. The listing gives a maximum speed of 12,500 RPM.
Because the size fields do not agree, confirm the diameter and arbor on the product page before buying. A three-tooth blade suits grass and light weeds rather than thick woody stems. The listing describes the carbon steel as high quality and durable, which is a manufacturer description.
Gashwer brush cutter blade combo, 9 inch 36-tooth and 10 inch 3-tooth
The Gashwer pack includes two blades in one set: a 9-inch 36-tooth carbide-tipped blade and a 10-inch 3-tooth blade. The listing describes the blades as forged from manganese steel and carbide. It gives a 1-inch center hole for most straight-shaft gas trimmers and says two full sets of adapter hardware are included.
The combo covers two jobs. The 36-tooth blade is for brush and thicker stems, and the 3-tooth blade is for grass and lighter growth. The listing describes the blades as universal for most straight-shaft trimmers. Check the arbor size on your trimmer before ordering, because the listing names a 1-inch arbor as the standard fit.
AXQKFZ 3-piece brush cutter head and metal blade kit
This kit includes two 6-blade steel cutting heads for heavy weeds and one 10-inch blade with 80 carbide-tipped teeth. The listing says the steel heads are for heavy weeds and that the carbide blade is for finer cutting. It includes adapter rings and washers for both 1-inch and 20 mm arbor sizes.
The listing says standard blades lose their edge fast in tough conditions and claims the carbide set holds an edge longer. That is the manufacturer’s description and is not tested in this guide. The kit is one of the few in the pack that combines a steel head with a carbide blade, so a buyer who wants both types in one set can compare it with the two-blade sets.
Kurt-Saw 9 inch 36-tooth carbide tipped blades, 2-pack
The Kurt-Saw pack has two 9-inch blades with 36 carbide-tipped teeth each. The listing describes them as precision-ground and built from high-carbon steel with a corrosion-resistant coating. It gives a standard 1-inch arbor and says the blades are made to fit most brush cutters and trimmers.
The 36-tooth carbide design is the most common choice for brush and thicker stems in this roundup. The listing does not give a weight or a maximum speed. A buyer who wants two identical carbide blades for a single trimmer can use this pack as a straightforward option.
AR-PRO 10 inch 80-tooth carbide tip brush blades, 2-set
The AR-PRO pack has two sets of 10-inch blades with 80 carbide-tipped teeth. The listing says they are made from carbon steel with heat and rust resistance. It says the blades fit most straight-shaft gas or electric trimmers and comes with a universal adapter kit.
The 80-tooth count gives a finer cut than the 36-tooth sets in this roundup, which the listing describes as cutting like butter with less pressure. The listing also describes the blades as useful for pruning and clearing garden paths. Because these blades are 10-inch, they cover more ground per pass than the 9-inch sets. Check the trimmer shaft’s rated load before using the largest blade.
PLUMIA 9 inch 36-tooth carbide tipped blades with universal adapter kit
The PLUMIA pack has two 9-inch carbide-tipped blades with 36 teeth and a universal adapter kit. The listing says the blades can be used on select Husqvarna, Stihl, Oregon and Hitachi trimmer models, which it describes as compatible with OEM blades on those brands. It includes two adapter kits with thrust washers and rider plates.
The brand list is the most specific fit information in this roundup. Several listings name a brand, but this one names four. A buyer with one of those brands should check that the model matches. The listing describes the blades as fitting most gas or electric trimmers, so check the arbor against your own trimmer before ordering.
In-depth look: the AXQKFZ 3-piece kit
If you want one set that covers both grass and heavy stems, the AXQKFZ kit is the most complete option in this roundup. It is listed as a three-piece kit: two 6-blade steel cutting heads and one 10-inch blade with 80 carbide-tipped teeth. That mix gives a steel head for heavy weeds and a carbide blade for a finer cut, in one purchase.
The adapter setup is the second point. The listing includes adapter rings and washers for both 1-inch (25.4 mm) and 20 mm arbors. A buyer with a 20 mm trimmer does not need a separate adapter. The listing names the standard 1-inch arbor as the most common fit, so check which arbor your trimmer uses.
The listing’s product dimensions are 5 by 6 by 0.5 inches and the item weighs 3.16 pounds, which is one of the few weight figures stated in this roundup. The listing says standard blades lose their edge fast in tough conditions, and it describes the carbide set as holding an edge for longer. Those are the manufacturer’s claims and are not tested here.
The listing does not give the tooth count of the steel heads, or the maximum speed, so check the product page before fitting the kit. Close alternatives in this roundup are the Gashwer combo, which pairs a 9-inch 36-tooth blade with a 10-inch 3-tooth blade, and the AR-PRO 80-tooth pack, which has two blades of the same type.
How to match a blade to the job
For grass and weeds in an open lawn, a 3-tooth blade or a steel head is enough. The vidica and Gashwer listings describe 3-tooth blades for this type of work. For brush and saplings up to the thickness the listing describes, a 36-tooth carbide blade is the better fit. The Kurt-Saw and PLUMIA listings both describe 9-inch 36-tooth blades.
For a clean, fine cut, an 80-tooth blade is the listings’ choice. The AR-PRO and AXQKFZ sets both describe 80-tooth carbide blades. A finer cut also puts more load on the trimmer, so the listing’s maximum speed and the trimmer’s rated power should be checked before use.
Blade size matters for the trimmer as well as the job. A 10-inch blade covers more ground per pass than a 9-inch blade, but it adds weight and load to the shaft. A buyer should choose the size the trimmer’s manual allows.
Safety and fit points from the listings
A brush cutter blade is a metal blade spinning at high speed, so the listings’ safety notes apply. Wear eye protection and gloves, keep bystanders clear and remove the spark plug or battery before fitting a blade. Check that the blade and the adapter are fully seated and that the collar nut is tight before you run the trimmer.
Use only the adapter kit that matches your trimmer. The listings say the adapter is brand specific, and a mismatched adapter can loosen during use. Check the thrust washer and rider plate for wear when you change the blade.
Keep the trimmer’s guard in place. Most straight-shaft trimmers have a guard to deflect debris, and the blade should not be used without it.
FAQ
What is a brush cutter blade for a weed eater?
It is a metal blade that replaces the string head on a straight-shaft trimmer. It cuts brush, saplings and thick weeds. The listings in this roundup describe 9-inch and 10-inch blades with 3, 36 and 80 teeth.
How many teeth should a brush cutter blade have?
A 3-tooth blade is for grass and light weeds. A 36-tooth carbide blade is the common choice for brush. An 80-tooth carbide blade gives a finer cut. The right count depends on the job, and the listings give the count for each set.
What arbor size do these blades need?
Most listings give a 1-inch (25.4 mm) center hole. The AXQKFZ kit and the vidica pack also include a 20 mm option. Check your trimmer’s arbor before buying, because the adapter kit must match the gear case.
Are these blades carbide or steel?
The pack includes both. Carbon steel and manganese steel blades are in the lower-cost sets, and carbide-tipped blades are in the 36-tooth and 80-tooth sets. The listings describe carbide as the harder material for brush.
Do these blades fit electric trimmers?
Some listings say they fit gas or electric straight-shaft trimmers, including the AR-PRO and PLUMIA listings. Check the bore and adapter fit on the product page for your model.
Why do some listings show different sizes?
The vidica listing’s title says 10 inches, but its spec fields say 5 inches. Listing fields in this pack are not always consistent. Confirm the diameter on the product page before buying.
Bottom line
For brush cutter blades for weed eaters, the right set depends on the job and the arbor. Choose the AXQKFZ kit for a single set that covers heavy weeds and a finer carbide cut. Choose a 9-inch 36-tooth carbide pack, such as the Kurt-Saw or PLUMIA listing, for brush. Choose the AR-PRO 80-tooth pack for a finer cut, and the Gashwer combo if you want a 3-tooth and a 36-tooth blade together.
