curcular saws

[FarmBoy]

can you use a regular curcular saw (with out screwing it up) to cut sheet metal or do you have to get a metal cutting saw?????

i have been useing my cordless to cut metal roof sheets for the new shop that were buliding at work and it seems to be cutting ok but i just dont know if it will really screw it up over time.

You can use a circular saw to cut sheet metal without any damage to yoursaw if you use an abrasive blade and not the regular wood cutting blade. I would keep it blown out with compressed air after each use though.
If you cut masonary with your circular saw and an abrasive blade, it will eat up the bearings in a short time. Same is true on fiber glass products.

It is better if the saw has a metal blade guard so it won't melt. trust me I know. Well if you use an abrasive blade.

they also make special blades that are not abrashive fpr tin and sheet metal it is a non ferrous metal blade i used one to cut believe it or not 1/4 inch thick steel yes it got hot but its all i had at the moment i think now ill just use my sawzall with a metal cutting blade on it

Non-ferrous is for things not steel. Usually aluminum and the like. I am not sure of the correct terminology. But usually ferrous means steel, non ferrous is non steel.

I am with you, thicker stuff, sawzall, or plasma cutter.
