Interesting presentation. I am curious about that abrasive wheel. I looked at the comments on YouTube. They are all in Spanish.

I used Bing Translator since I am not multi-lingual. I find it very handy on this world wide forum.

This is what I got.

Comment --> Que piedra es la que usa. ---> What a stone he uses.

Response --> gracias por tu interés, es un disco diamantado que compre en amazon -->Thank you for your interest, it is a diamond record that you buy on Amazon

I searched for "flat lap disk" and found many different wheels. None mention being used to cut steel. I wonder how long that wheel would last cutting steel like that? I know that I have ruined more than one diamond wheel cutting concrete and hitting a piece of rebar.
