[Metal Cutting]

I'm cutting steel floor tiles which are approx an 1/8 in thick. the back is ribbed and the ribs are hollow but over an 1 in thick. I've been using a 4 1/2 in grinder with a cutting wheel to cut the smoothing the edges with a grinding wheel. Can I do it easier, faster and safer with another tool.. also i've started using a 5 in grinder now..

thanks in advance;..

go steelers...

[angle grinder vs right angle grinder]

is there a difference between the two.. the right angel grinder seems to cost more but they look the same.
