I'm removing a chain link fence from my yard. I've been using a Roto-Zip with a metal cutting wheel to cut the chain-link material into manageable pieces. That works very well, by the way.
I'm going to need to cut the vertical metal pipe poles as close to the ground as possible. They're set in concrete footings and I suppose if I was younger and more ambitious I might try to dig them out. But the poles feel really solidly anchored, and the footings are below the level of the dirt.
Anyway, I see two angle grinders in the latest edition of the Harbor Freight catalog. Both are priced at $30, one 4.5" and one 7". The 7" has a 1.66 hp motor and the 4.5" one is something like half that. It seems that the 7" wheel would allow me to cut through the approximately 1.25" o.d. pipe without having to keep moving the tool around different sides of the pipe. But the metal cutting wheels they advertise say they have a 1/4" face. That seems pretty thick to me, removing more material than might really be necessary. Might the 4.5" tool be better in some way?
I don't imagine I'll be using an angle grinder too often for other tasks, so I'm hoping the likely rock-bottom quality of these tools won't be too much of a problem.
