Best Electric Weed Eaters With Saw Blade Attachments
As an Amazon Associate we earn from qualifying purchases.
An electric weed eater with saw blade setup swaps the usual trimmer string for a metal or carbide blade that can cut thicker brush and small branches. This roundup covers eight saw blade listings that are described for weed eaters, trimmers and brush cutters. The listings give different diameters, hole or arbor sizes, piece counts and tooth counts, and some leave gaps. Measure your trimmer shaft and check your owner’s manual before you choose a blade.
Quick answer
- Match the hole or arbor size first. The listings in this roundup show 5 mm, 6 mm and 1-inch arbor fittings, and a blade with the wrong bore will not seat correctly.
- For thin shrubs and light branches, the 6-inch sets in this list are the smallest options.
- For thicker brush, look at the 8-inch, 9-inch and 10-inch listings, especially the 80-tooth carbide blades.
- Keep the power off and wear gloves whenever you change a blade, as the listings advise.
How to choose a saw blade for your trimmer
Start with the attachment point on your machine. The listings here use two kinds of center opening. Some sets have small holes of 5 mm or 6 mm that fit a bolt-on hub, while others list a 1-inch arbor that takes a larger brush cutter blade. The Yutacorex and Dunhi listings describe 1-inch arbors, and the Yutacorex listing also names gear head adapter kits for specific STIHL and Husqvarna models. If your machine uses a gear head, check the gear head part number before you order anything.
Diameter comes second. The 6-inch blades are the smallest in this list, and the CGNRONEAU listings describe their circular blades for thicker shrubs and branches. The 8-inch and larger blades give a wider cutting reach, so pick the smallest size that does the job. Tooth count is the third check. The 40-tooth carbide blade and the 80-tooth carbide blades carry the higher tooth counts in this list, while the 20-tooth blades are described for brush and small stump work.
If you are also servicing a mower, a separate guide on how to replace an electric mower blade safely covers the same basic habit of cutting power first, and it is worth reading before you start. For a broader look at battery trimmers that you might pair with a blade, see the comparison of battery powered weed eaters on this site.
Fit, arbor size and the numbers side by side
The table below puts the values from each listing next to one another. Where a listing does not give a value, the cell says “not stated” so you can see the gap at a glance.
| Listing | Diameter | Center hole or arbor | Teeth | Pieces in package |
|---|---|---|---|---|
| CGNRONEAU 7-piece set | 6 inch | 5 mm | not stated | 7 |
| TWRSHE saw and brush cutter set | 6 inch (saw blades) | not stated | 4 teeth (brush cutter blades) | 3 saw blades and 4 brush cutter blades |
| Carbide tipped 7-piece set | 6 inch | 5 mm | 40 | 7 |
| CGNRONEAU 8-piece set | 6 inch | 6 mm | not stated | 8 |
| ATIE carbide tip blade, 2 pack | 8 inch | 1 inch or 20 mm arbor | 80 | 2 |
| Dunhi brush cutter blade kit, 2 pack | 9 inch (230 mm) | 1 inch arbor | 20 | 2 |
| MTR 9-inch bundle kit | 9 inch | not stated | not stated | not stated |
| Yutacorex carbide tip blade, 2 pack | 10 inch | 1 inch arbor | 80 | 2 |
Two rows need a closer look. The Dunhi model field reads “2 Pack 7 inch 16 Teeth”, which conflicts with the 9-inch and 20-tooth values in its title and bullets, so the table uses the title. The MTR title says 7 or 9 inches, and the table shows the 9-inch kit because that is the version named in the product title.
Blade material and tooth count
The materials in this roundup fall into three groups. The CGNRONEAU and TWRSHE sets are described as manganese steel, which the listings present as a durable choice for brush and thin branches. The carbide tipped blades from the 40-tooth set, the ATIE listing and the MTR bundle are described as carbide construction, and the ATIE listing gives an estimate that its carbide tips last about ten times longer than plain steel. The Dunhi blade is carbon steel, and the Yutacorex listing describes premium stainless steel with carbide tips.
Tooth count affects the feel of the cut more than the material does. An 80-tooth blade spreads the work across more cutting edges, and the ATIE and Yutacorex listings both use that reasoning. The 20-tooth Dunhi blade is described for brush clearing and small stump removal. None of the listings gives a cutting speed in inches per minute, so compare by the tooth count and material rather than by a speed claim.
Who each type suits
Small multi-piece sets make sense for someone who wants spares and a tool kit in one box. The CGNRONEAU 7-piece and 8-piece sets include a wrench, nuts and shims, so you do not need to hunt for parts at the moment you need them. The TWRSHE set adds four brush cutter blades alongside its saw blades, which suits a person who switches between grass and brush during the same session.
Single-diameter two-packs suit people who know exactly what size they need. The ATIE, Dunhi and Yutacorex listings each come as two blades, which gives a spare for each job. The MTR listing is a bundle kit, which suits someone who wants the blade and its included parts in one order. Larger blades like the 10-inch Yutacorex are for owners of gear head machines who have confirmed their model number first.
Roundup: eight saw blade listings
CGNRONEAU 7-piece manganese saw blade set
This set holds two circular saw blades, one lawn mower wrench, two nuts and two shims, which the listing counts as seven pieces. Each blade is 6 inches across with a 5 mm center hole and a thickness of 1.1 mm. The listing describes the manganese steel circular blade as suitable for thicker shrubs and branches, and it also mentions small branches and soft grass. The bullets say the blade suits lithium battery weed whackers and cordless mowers, so check that your shaft matches the 5 mm hole before you order.
TWRSHE manganese saw blade and steel brush cutter set
The TWRSHE set includes three manganese steel saw blades rated at 6 inches, four four-tooth steel brush cutter blades, one wrench, two nuts and one shim. The listing says the round saw blades help with precise edging and hedge trimming without harming plants you want to keep, and it describes the four-tooth blades for lawns, weeds and small branches. The listing also asks buyers to store unused blades in the original packaging with the oil inside. It names TWRSHE multifunction weed eaters and similar weed wackers, so confirm the fit against your own model.
Carbide tipped 7-piece blade and attachment set
This seven-piece set has two 6-inch blades with 40 teeth and carbide tips, plus an Allen wrench, two spacers and two nut screws. The listing gives a 5 mm center hole and a 1.44 mm thickness, and it says the two metal blades together weigh 0.58 lb. The bullets describe each carbide tooth as sharp and say the metal blade can remove bushes, vines and dead flowers. The listing also says it can cut weeds growing through blacktop or concrete. Its title calls the blade an edger blade as well, so it is a reasonable choice for edging tasks.
CGNRONEAU 8-piece saw blade set
The eight-piece version of the CGNRONEAU set includes two lawn mower saw blades, one circular saw blade, one wrench, two nuts and two shims. The listing gives a 6-inch diameter, a 6 mm saw blade aperture and a 1.44 mm thickness. It says the metal blade has high toughness, does not break and can be polished at any time. The package note describes the blades for grass, weeds, bushes and thorns, and it repeats the warning to keep the power off when changing blades. Because its hole is 6 mm rather than 5 mm, compare it against your hub before you buy.
ATIE 8-inch 80-tooth carbide blade, two pack
This two-pack has two 8-inch blades with 80 carbide-tipped teeth that the listing describes as brazed-welded. Each blade fits either a 1-inch or a 20 mm arbor, and the package includes a washer with each blade. The listing estimates that the carbide tips last about ten times longer than plain steel, and it says the extra teeth create more cutting surfaces for longer durability. The listing also says the manufacturer is CE certified. Its 8-inch size sits between the 6-inch sets and the 9-inch and 10-inch blades, so it is a middle step for thicker brush.
Dunhi 9-inch 20-tooth brush cutter blade kit
The Dunhi kit is a two-pack of 9-inch metal brush cutter blades with 20 teeth. The listing describes the blade as carbon steel, which it calls sharper and more durable, with impact and wear resistance. It gives a maximum speed of 10,000 RPM and a 1-inch arbor, and it describes the blades for large brush, weeds and small stump removal. The title mentions adapter kits for STIHL. The model field conflicts with the title, as the table above notes, so confirm the diameter and tooth count with the seller before you buy. The listing also carries a strong warning to read all power tool instructions first.
MTR 9-inch saw chain style brush cutter blade kit
The MTR 9-inch version is sold as a two-pack bundle kit. Its title says the blades come in 7-inch or 9-inch sizes, and the bullets describe the carbide construction as heavy duty for small trees and large trees. The listing says the blades fit most gas and electric trimmers and run up to 10,000 RPM. It also notes that the teeth can be sharpened with a round file, which the listing presents as a way to keep the teeth sharp. The listing does not state the center hole size, the tooth count or the thickness, so check those against your trimmer before you order.
Yutacorex 10-inch 80-tooth carbide blade, two pack
This is the largest blade in the roundup and the one that needs the most fitting care. The listing gives a 10-inch diameter with 80 teeth and a 1-inch arbor hole. It is the blade to choose when you have a gear head machine and have already confirmed the model. The full product walk-through is in the deep look section below.
Deep look: the Yutacorex 10-inch carbide blade
The Yutacorex listing is the most detailed in this roundup, so it is worth reading all of its bullets. The blade is described as a 10 by 80 tooth carbide tip brush blade with a 1-inch arbor bore. The body is described as premium stainless steel, and the carbide tip is estimated to last about ten times longer than plain steel. The listing says it is compatible with Husqvarna, STIHL, EGO, RYOBI and other brands with mower heads that have a 1-inch arbor hole.
Fitting is where this listing needs attention. It includes a 10-tooth adapter kit for a long list of STIHL models, including FS56RCE, FS91R, FS70R, FS94R, FS111R, FS131 and FS91. It also includes a 6-tooth adapter kit for a long list of Husqvarna and Jonsered models, such as 135R, 232R and 535RX. The listing supplies two adapter sets, each with a thrust washer, a rider plate, a collar nut and a tool, and it warns that different adapters fit different mowers. Check the mower model number or the gear head part number before you buy, because the adapter is the part that decides whether the blade will mount.
The listing says the blade is good for weeds, brush and small tree trunks, and that it can cut blackberry bushes. It also tells the user to wear heavy-duty leg guards and goggles when running brush blades. For a close alternative in the same 80-tooth family, the ATIE 8-inch two-pack gives a smaller diameter with a 1-inch or 20 mm arbor option. For a bundle that includes its own parts, the MTR 9-inch kit is the other option in this list.
Mistakes to avoid
- Ordering by title alone. The Dunhi model field and the MTR title disagree on size, so read the full listing before you buy.
- Skipping the arbor check. A 5 mm, 6 mm and 1-inch fitting are not interchangeable, and a gear head machine needs the right adapter.
- Changing a blade with the power on. Several listings repeat this warning, so make it the first step each time.
- Removing the guard. The CGNRONEAU listings say it is forbidden to remove the weed eater guard and use the blade.
- Working without gloves. The blades are sharp, and the listings tell you to wear gloves while changing them.
FAQ
Will one saw blade fit every electric weed eater?
No. The listings name different holes and arbors, from 5 mm and 6 mm centers to 1-inch arbors, and the Yutacorex listing names adapter kits for particular STIHL and Husqvarna models. Read your trimmer manual for the shaft and hub size, and match the blade to that number. If your model is not named in a listing, ask the seller before you buy.
Which blade size is best for thick brush?
The larger diameters in this list, 8 inches, 9 inches and 10 inches, reach farther into dense growth. The ATIE and Yutacorex listings both describe 80-tooth carbide blades for thicker brush, and the Dunhi listing describes its 20-tooth blades for large brush and small stumps. Start with the size that fits your trimmer, then choose the tooth count that suits the stems you cut.
Do these blades replace the string head?
Most of these listings describe the product as a replacement blade for a trimmer, so the string head is normally removed before the blade is fitted. The exact steps depend on your machine, so follow the owner’s manual for removing the head and mounting the blade.
Are saw blades safe to use on a trimmer?
They can be used safely when the power is off, the guard stays in place and you wear gloves and eye protection. The Yutacorex listing also recommends heavy-duty leg guards and goggles. The Dunhi listing carries a warning about serious injury and asks you to read all power tool instructions first. Treat every blade in this roundup as a cutting tool, not a casual accessory.
How long do the carbide blades last?
The ATIE listing estimates that its carbide tips last about ten times longer than plain steel. Other listings do not give a lifespan, so the answer depends on the material, the tooth count and how much grit and stone the blade meets. Inspect the teeth after each job, and sharpen or replace a blade that chips or wobbles.
Bottom line
Choose by hole size first, then by diameter, then by tooth count. If your trimmer takes a 5 mm or 6 mm hub, the CGNRONEAU and carbide tipped 6-inch sets are the simplest starting point. If your machine uses a 1-inch arbor, the ATIE, Dunhi and Yutacorex listings are the ones to compare. Confirm the fit with your manual before you order, and keep the power off every time you change a blade.
