Cutting and sanding/buffing galvanized steel

angle-grindermetalmetal-cutting

I have 3/4" galvanized steel bars (hollow) that I bought from Lowes. I'm looking for a tool that will cut through them and sand/polish the cut surfaces smooth so that there are no metal burs or slivers; I need it to be completely bur/sliver-free by the time the sanding is done.

My first thought was that using a sawzall with a metal cutting blade would easily do the cutting, but then I'd probably need to use a hand file to sand it down, and that feels like it would take a long time to do it right.

So now I'm leaning towards purchasing/renting an angle grinder, and I'm hoping they come with different disks/heads for doing the two tasks I need done: (1) for cutting the steel and (2) another one for sanding/buffing the metal smooth. One tool to do both jobs and I've have it for future projects down the road as well.

So I ask: is this angle grinder solution feasible? If not, why and more importantly, what is?! And if so, then what types of disks/heads would I need to do both jobs? FYI I'm thinking about this Dewalt grinder unless anyone here has huge objections!

Thanks in advance!

I would use a 4-1/2"- 5" angle grinder, I have dewalt, bosh, Makita and even a harbor freight. I use the very thin metal cutting disks fro cutting steel all the time, after cutting a pass done at a 90. a quick 45 will take the sharp edges off, if I want to polish or buff I use sanding disks, if I want to take rust off I will use a wire cup brush, in all cases it is a really good idea to wear eye protection , a face shield is even better with a good pair of leather gloves both to protect from the hot sparks from the cut but also from the metal it will get hot also. If you go with a grinder it can also be used for masonary just change disks. I probably have more angle grinders than any other power tool because the are so many uses for them.
