will this work on a cordless dewalt DWE 4011?

Not sure about the dewalt But it does not fit my Makita cordless the bore size is to big for mine , and I bought 2 blades ,so be carefull

Can this be used on porcelain tile?

Thanks for your asking. This wheel is designed for cutting and grinding Granite Marble and concrete. If you are not very high precision requirements for cutting and grinding tile porcelain, this disc could be used for your working. If you have high requirements for the accuracy of tiles and porcelain, we don't recommed it.
