...my inner, sane, voice said "Do NOT buy this! It will kill you." The 1st one was a huge, seemingly bigger than a big Harley, Zundapp motorcycle ($50 in 1967). The 2nd was those chainsaw blades for angle grinders.
...Well, I bought the chainsaw blades last week. Damn, those things are scary.
(to which my friend Dave replies:)
This is the 12" attachment for the grinder that moves so fast is will sever a limb before the first drop of blood spatters into your face?
RC:
No, I'm not that insane ...yet.
I bought 4.5" discs.

I'm using them to clear weeds & brush in tight places. Helluva weedeater, hhh.
I bought a blade for a Craftsman weed eater that was just like a circular saw blade but made for a weed eater. The first time I used it, it was whizzing about 5 feet away. I tried approaching from the left and then the right. Both times it kicked back. I brought it back to Sears the next day. They asked what was wrong with it. My reason of being deathly afraid of it didn’t seem right so they said it was out of balance or something.
I like the real chainsaw blade design with the separate chain running in a groove rather than the more available/popular models with the teeth individually riveted to the plate. Supposedly, if it binds the chain will slip, reducing kickback.
The 7" blade fits the Ryobi 18v Expand-it weedeater straight out of the box, no arbor adapters. For my use, I like the 18v powerhead being slightly underpowered --more manageable than the higher torque Stihl 2cycle. The 18v was still powerful enough to cut through a 1-1/2" branch. The 4ah battery lasted longer than I did, heh.
