Welcome to MultiRotorForums.com!!
I use a small metal pipe cutter like this one...cuts like butter, zero splinters

I have a vacuum attached to a milk container at the back to catch the dust
that little saw is pretty similar to what i'm trying to do with my angle grinder and the base i bought for it today. if i had been exposed to the rockwell saw you linked to i'd have probably bought that instead though.
maybe next time...
