I know this has has been discussed before and I did a search but can't find what I want. I'm thinking of either getting a metal circular saw or a metal blade for one of my wood saws. Anyone used a metal blade on the wood saw? If so, how did it work, what brand etc? Again, I'm talking about 71/4 circular saws. The only way I have to cut a sheet of steel effectively is a plasma cutter. I have saws for everything else.............thanks for any info
