Depends on how many teeth the blade has and the offset. It’ll cut!
I have Roger. I started out using the Echo kit but even though it worked good I got tired of having to sharpen a regular steel blade. I researched using a regular 7 1/4” circular saw blade. As I mentioned before it’s the type of blade you use makes it work. I’ve been using an old 7 1/4” carbide circular saw blade, 24 tooth, crosscut or framing blade. This blade probably now costs less than $10. A blade that says Stihl brush blade probably costs three times that. It’s your choice.
There’s a lot of them out there. The older brush blades were the three star type but the circular blade later became the best choice. My Echo kit worked great but it only had a steel blade and needed sharpened a lot. I researched using a simple circular blade because I have a lot of them. Depending on your trimmer you may need an adapter kit or just a bushing. You can’t go crazy and use these like a chain saw. Most of my use was small saplings maybe an inch or smaller clipping them off at ground level. Slicing through brush was like cutting through butter. Most good carbide brush blades are well over $30. or more if they have the leading brand names on them where you can get a 7 1/4” carbide blade for less than $10. My 24 tooth framing blade works great.
