8" x 80T 8-Inch 80 Tooth Carbide Tip Circular Saw Brush Cutter Trimmer Weed Eater Blade (2 Pack)

TL;DR this thing works much better than Echo's own blades with an Echo 58V electric power head and Echo brush cutter attachment. 1 inch saplings are gone without really slowing down, 2 inch only takes 2-3 seconds, and bigger trees are possible. Heavy weeds, false bamboo, etc. is gone almost instantly. I also trimmed a couple of pine trees. (It also looks like something it would be very effective during the zombie apocalypse, but I digress from the spirit of the TL;DR). Important note: some brush cutters, including my Echo, have blades mounted with left-hand threaded hardware. If you've been huffing and puffing all day to no avail, turn it the other way. I have an Echo 58V electric power head that takes the same interchangeable accessories as the gas heads. It's a demon of a string trimmer. (I reversed the string trimmer cutoff, which gives it another 2 inches diameter cut, without a problem). I decided to try the Echo 8 inch brush cutter attachment (99944200601) which is a bit spendy but it includes an upgraded handle for the power head, and a complete brush cutter (shaft, gear box, blade mount, guard, blade) so you just pop off the string trimmer (turn the safety release, turn the lock knob 2 turns, pull) slide one tool out and the other in, and it's ready to go in 20-30 seconds. Echo's own blade sucks. It's thick, solid steel, goes dull quickly (ever sit down with a file and sharpen an 80 tooth blade, one tooth at a time?). This is important, as the 58V electric head is actually more powerful than the smaller gas heads, but the controller is conservative in how it protects the motor and the "stall protection" shuts the motor down when the load gets too high, and it won't restart until it's coasted to a stop. So a dull blade means more friction and more stalls. The fairly wide kerf of 2.58mm (0.1in) contributes to stall-causing friction. The blade is heavy, weighing in at 420g (14.8oz) it occasionally triggers the stall protection accelerating to speed, or as you swing the cutter (I won't get into the physics of gyroscopic precession: basically, rotating masses do not like to change course in mid flight). So, three rounds of running it dull and sharpening it up (note that I do this without removing the blade from the tool, which is why I never noticed it's left-hand thread) and I'm ready for a new blade. Carbide, because carbide. The ATIE looked nice. Ordered, received, unpacked, and it is nice. Some of the "hybrid" style blades looked even more aggressive, but I've heard other people with electric heads say they're problematic. Mass dropped 38%, from 420g to 260g, which is just enough so that the thing is much less likely to stall when you floor the motor, or swing the tool around. One problem solved. The kerf dropped 16%, from 2.58mm to 2.18mm, so even if it was only as sharp as the Echo steel blade I'd still be ahead of the game, friction-wise. But the ATIE carbide is much sharper than the Echo steel, so friction drops a lot more than 18%. I know what a new or freshly sharpened Echo blade feels like (and I even have some videos from when I first got the brush cutter) and it's like night and day. The sort of small tree that would have been 10 seconds and risked stalls is now about 2 seconds, and no stalls. Another problem solved. Past the kerf, the ATIE has a 1.35mm thick blade, which is 0.83mm thinner than the kerf. The Echo blade's 2.20mm blade is only 0.38mm thinner than the kerf. This means there's a lot more room for the ATIE to slop around inside the cut without jamming. Cutting is easier, less pron to stalls, and more controlled. Remember, a thick trunk will attempt to clamp down on your blade as you cut through, so you're probably still better starting off with a 1 inch V-notch, deepening to 2 inch, then to 3 inch. Yes, that's 5 or 6 cuts for a 3 inch trunk, but then again, it's a 3 inch trunk, which is outside the realm of what one calls "brush cutting". Another problem solved. Oh, and the official Echo blade is $26 for one, instead of $20 for two ATIE blades. Remember, when removing branches, cut down onto the branch, not up. Aside from being much safer, cutting down means the notch opens up as you cut and doesn't clamp the blade. For those of us lacking sanity or intelligence, or who are too smart for our own good (my job titles have included "chief scientist", "technical fellow", and "subject matter expert") this blade can theoretically bury itself into more just over 3 inches of wood before you hit the blade clamp. But if you use it like you'd fell a tree with an axe (notch from one side than the other, then "timber") it will take down a 4 or 5 inch tree with surprising ease, although 5 inches is 9 cuts (2 for a 1 inch V-notch, 2 to turn that into a 2 inch V, 4 more for a 2 inch V from the other side, and if it's still standing one more cut is going to let it loose. Remember, just because it's easy doesn't mean it's smart! I'd still recommend against going after 4 or 5 inch trees with a brush cutter.

These things are beastly! I was cutting down small 2" trees with this thing on my Echo 225,and it didn't even stutter. Gives a great cut, and the carbide blade chews up anything you hit with it. WAY better than the OEM blades. Highly recommended. Will definitely buy again (if the ones I bought ever wear out! 😅)

Blades cut good, but spacer ring is a bit of a pain to get it right when bolting blade to adapter on trimmer head.

These go through brush like professionally sharpened surgical steel goes through melted butter. I "zinged" through several 2" ash tree suckers without any issues, these just go right through them. 1" trees and brush are a joke to this brush blade. Briars? Bwah-ha-ha-ha. No more breaking string line on stupid briars any more. I can hear this blade "sing" with a high bell-like tone when it passes through some stuff, its music to my ears. My only regret is that I didn't get these 8 years ago. Way back then, I don't know from where, I got a "brush blade" that has only 4 blades, sort of like a lawnmower blade. I cleared a lot of property with that awful thing, and I would have to "chop" into the brush with it to get it to work. I also had to sharpen it a lot. Honestly, that old thing was more work than I had ever imagined, and I felt downright foolish when I installed this new blade onto my straight shaft for my my Husqvarna 28cc 2-Cycle 128Cd and went through some brush in maybe 1/10 the time and about 95% less effort. This thing is so effortless, I'm sure to wear my steel-toed boots, and I would recommend the same for you. These blades make working on my property a blast!

This is a great brush cutter. I call it the wheel of death (for brush). I used to think a router was the most dangerous tool to use in my arsenal. After using this I've changed my mind and this is it. Attention, and care, during use is required. I'm using this on a Troy Bilt TB42 brush cutter. The blades themselves fit on a 1" arbor which the TB42 has. Note the little O shaped adapters included allow the blades to be used on a 20mm arbor as well. When using the adapters they fit inside the 1" hole in the blade and then you'd put the entire assembly in your unit. If your unit has a 1" arbor you'll end up throwing away the 20mm adapters since you don't need them. The blades themselves are great. I have a full day cutting large (4" trees) to small (thorny vines) brush and have zero complaints. The carbide tips stay sharp and cut quick and clean. I have no reason to believe that with careful use a single blade should be able to last a season of brush cutting. The inevitable hit against a rock, steel fence post, the ground or other non sawable object will impact any blade but carbide should handle abuse better than ordinary steel blades (or the chainsaw style wheels). If brush cutting is your thing, or need, I'd highly recommend these blades. Just be sure your arbor is either 1" or 20mm and your cutter can handle an 8" blade and you should be good to go.

I have to say that I was exited at first when I started using this blade, but it has not lasted 10 hours before becoming so dull it burns through small branches a and does not cut them. Yes, I have hit the dirt a couple of times ,but I have been using carbide tipped blades fro years and hit the dirt with them and they never dulled like these blades did.

I live in Missouri where invasive honeysuckle is a thing. I have a 2 acre property that has a 20 foot wide boarder of the stuff. I purchased these, along with the Stihl # 4117 710 8200 guard, for my Stihl FS 131R Pro Loop Handle String Trimmer and went to work. A word of caution: they ain’t kidding this blade can/will kick back IF you cut into something substantial while sweeping to the right. Even though I did do that a couple times, it still was no big deal since I had a firm grip, and respect for the blade. Sweeping to the left when cutting, which the proper technique, had NO issues. These blades worked great. After 12 hours of cutting tough honeysuckle I’m still going strong with the first blade. So heck yes I’m happy with this purchase. I had got a quote of $8,000 from a feller with a forestry mulcher; so the cost of these is nothing in comparison. ...and much easier to clean up the area as I went along.

Blades work but not a good match for my echo 225 . A person would be better off using these with a more powerful weedeater. Mine is 21 cc which does not have enough power .

Semble de bonne qualité mais j’ai pas encore eu l’occasion de les essayer

Malísimo este producto en México nada de filo y se acaban en menos de lo que piensas extremadamente unitiles

Très satisfait de mon achat, bonne qualité !

fit right

I have gone through quite a few blades and for what I do with them (property/field edge maintenance) and they’re usually destroyed in a day. However, with these I might get a bit longer out of them and I’m surprised. I was expecting the carbide to be missing in short order, but I am happy to report all is still intact and none have entered my shins as an added bonus. Held an edge pretty well, even after the occasional rock encounter. Will purchase again, cheers
