Folks -

I am going to be removing a bunch (maybe 8) of 60 year old basement windows, the kind in which the frame is embedded in the concrete. I've never done this before, but apparently the first step, after removing the sash, is to cut across the frame so you can pry it out with a crow bar. I'm looking for recommendations on which blade would make this cut easiest.

I have two angle grinders, one the standard 4.5 inch size (makita), and the other a monster 9 inch, 15 amp milwaukee. The bigger one is probably too heavy and awkward for this job, but I wonder if the weight would be an asset in cutting the bottom of the frame at least.

Also, if anyone's done this job, would this be a good job for which to get a Harbor Freight cheap grinder rather than use my nice makita which I got for power carving?

Thanks - Ken
