When the trimmer line stops being enough, the fence line tells the story: blackberry canes, saplings, and thick stalky weeds that shrug off string. Swapping the head for a steel blade turns a weed eater into a clearing tool, but only if the blade matches the trimmer. The listings below all describe blades for common gas and battery straight-shaft trimmers, and this guide compares what each one actually states, so you can pick the best brush cutter blade for weed eater work on your own ground.

The HK kit is the only listing here with two different blades: a 9 in 36-tooth carbide tipped blade for woody growth and a 10 in 3-tooth blade for clearing, plus two universal adapter sets that fit 1 in arbors (20 mm or 25.4 mm) on straight-shaft gas trimmers from the listed brands. The listing describes the blades as carbide tipped and easy to install, and gives an item weight of 2.05 pounds. Note that the spec table lists Compatible Material as Metal while the title and bullets say carbide tipped; trust the title and bullets. It does not state a maximum RPM or a warranty term, so check the trimmer manual before you run either blade.

Read the full review
This second CalPalmy listing covers the same ground as the first: two 9 in 20-tooth chainsaw tooth blades, 3 round files and 4 washers, a 1 in arbor and a 10,000 RPM maximum, for gas or electric straight-shaft trimmers from Husqvarna, Stihl, Ego, Oregon and Hitachi. One line in the bullets calls the teeth carbide while the material type is carbon steel, so read both before you buy. Item weight is 16 ounces. No warranty term is stated.

- Rated to 10,000 RPM on a 1 in arbor

Cons
- The bullets mention carbide teeth while the material is listed as carbon steel, so read the listing carefully
- No warranty term is stated
- Chainsaw-tooth blades suit woody brush, not fine trimming
- The maker's 'cuts like butter' wording is a claim, not a measured result
Dunhil 7 in 16-Tooth Brush Cutter Blade Set with 9 in Adapter Kit
7 in 16-tooth chainsaw tooth blade with a 9 in adapter kit, in carbon steel for a 1 in arbor at up to 10,000 RPM.
Who it's for: owners who want the lowest stated diameter here for close work around beds and fences.
Who should skip it: anyone who wants the box contents nailed down, since the listing contradicts itself on the 9 in blade and the pack count.
Read the full review
The Dunhil listing needs a careful read. The title promises a 7 in plus 9 in set with 2 set adapter kits, but the bullets describe only the 7 in chainsaw tooth blade with 16 teeth, carbon steel, a 1 in arbor and a 10,000 RPM maximum. The spec table says Number of Items 1 while the model name says 2 Pack, so confirm the box contents before you buy, trusting the title and bullets over the spec table. The maker lists it for small trees, woody grasses, shrubs, thick weeds and tall grass, and recommends heavy duty leg protectors and eye protection. Item weight is 16 ounces.
Pros
- 7 in diameter, the lowest stated diameter here, for tight spots
- Carbon steel, rated to 10,000 RPM on a 1 in arbor
- 16 teeth suited to small trees, woody grasses and shrubs per the listing
- 16 ounces, tied for the lowest stated weight here
Cons
- The title promises a 7 in and 9 in set, but the bullets detail only the 7 in 16-tooth blade
- The spec table says Number of Items 1 while the model name says 2 Pack
- No warranty term is stated
- The listing names no compatible trimmer brands

Choosing the Best Brush Cutter Blade for Weed Eater
Chainsaw-tooth, carbide-tipped, or multi-tooth
The blades here fall into three styles. The two CalPalmy kits use 9 in 20-tooth chainsaw-tooth blades in carbon steel, made for biting into woody stalks. The VIDICA and HK blades are 9 in 36-tooth carbide-tipped blades, with the highest tooth counts here for mixed growth. The HK kit adds a 10 in 3-tooth clearing blade for open cutting. None of the listings claims one style for every job, so match the tooth style to what grows on your ground. For a broader look at trimmer blades, see our best brush blade for trimmer roundup.
Arbor size and RPM rating
Every blade here lists a 1 in arbor, with the HK kit also fitting 20 mm or 25.4 mm arbors. The two CalPalmy kits and the Dunhil state a 10,000 RPM maximum; the VIDICA and HK listings state no RPM limit, so check the trimmer manual before you run them. A blade may only be used on a trimmer rated for it, so confirm the shaft type and RPM in the manual first. Our string trimmer types guide explains shaft and power differences.
What the kit should include
A blade alone is only part of the job. The two CalPalmy kits include 3 round files sized 3/16 in for a .325 in chain pitch, plus 4 washers with a 20 mm inner and 25 mm outer diameter. The VIDICA and HK kits include universal adapter sets for mounting. The Dunhil title mentions 2 set adapter kits, but the bullets detail only the 7 in blade, so confirm the box contents. Keep the files with the blades; a dull blade gets swapped for the spare instead of a store run.
Blade diameter and the work
Diameter runs from 7 in on the Dunhil to 10 in on the HK clearing blade, with the rest at 9 in. A 7 in blade fits tight spots along fences and beds, while 9 and 10 in blades cover more ground in open brush. All five listings describe straight-shaft gas or electric trimmers as the host tool, so curved-shaft owners should check the manual. The heavier kits (2.05 pounds on the HK, 1.12 kg on the CalPalmy) change the balance of a trimmer, so plan accordingly if the weight is new to you.
Wear eye and hearing protection, long pants and sturdy footwear, and keep bystanders well back while the line or blade spins. Clear stones and debris first, and stop the engine or remove the battery before clearing the head. Refuel only with the engine off and cool. See OSHA landscaping safety. Read our Safety Disclaimer.
Matching It to Your Property
- Fence lines and ditch banks choked with woody stalks: the 9 in 20-tooth chainsaw-tooth kits list straight-shaft gas or electric trimmers from Husqvarna, Stihl, Ego, Oregon and Hitachi at up to 10,000 RPM.
- Mixed grass, thick weeds and small trees: the 9 in 36-tooth carbide-tipped blades pair with universal adapter kits for most electric or gas trimmers.
- Tight spots between beds and along walls: the 7 in 16-tooth blade is the lowest stated diameter here.
- Storage: keep the steel blades, files, washers and adapter parts together in a dry shed so the next blade change needs no store run.
The Acre Score explained
The Acre Score weighs five factors: performance (cutting ability for the stated applications), build quality (materials and construction), value (kit contents versus the stated specs), safety (stated safety features), and warranty (stated warranty terms).
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| HK 36T + 3T Blade Kit | 9.5 | 32 | 21 | 21 | 0 | 0 |
| CalPalmy 20T 2-Pack | 9.5 | 30 | 21 | 21 | 0 | 0 |
| VIDICA 36T 2-Pack | 9.5 | 30 | 21 | 20 | 0 | 0 |
| CALPALMY 20T 2-Pack | 9.5 | 30 | 20 | 20 | 0 | 0 |
| Dunhil 16T Blade Set | 9.4 | 28 | 19 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: mowing large lots
Will a brush cutter blade fit my weed eater?
All five listings describe blades for straight-shaft gas or electric trimmers with a 1 in arbor (the HK kit also fits 20 mm or 25.4 mm arbors). Check the trimmer manual for the shaft type and any blade RPM limit before you buy, and confirm the arbor size on your trimmer.
What is the difference between chainsaw-tooth and carbide-tipped blades?
The two CalPalmy kits use 9 in 20-tooth chainsaw-tooth blades in carbon steel; the maker describes them as cutting woody growth cleanly. The VIDICA and HK blades are 9 in 36-tooth carbide-tipped blades that the listings describe as strong and long-lasting. Match the style to the growth: chainsaw tooth for woody stalks, more teeth for mixed grass and weeds.
What RPM can these blades handle?
The two CalPalmy kits and the Dunhil list a 10,000 RPM maximum. The VIDICA and HK listings state no maximum, so the trimmer manual is the authority there. Never run a blade above the lower of the two ratings.
How do I sharpen a brush cutter blade?
The two CalPalmy kits include 3 round files sized 3/16 in for a .325 in chain pitch, which the listing pairs with the 20-tooth blades. The other listings include no sharpening files, so a file or a spare blade covers the same need.
Do I need an adapter kit to mount the blade?
The VIDICA and HK kits include universal adapter sets, and the Dunhil title mentions 2 set adapter kits. The CalPalmy kits include 4 washers for mounting. Check the box contents against the listing before the first blade change.
