Depends...
I have not used all of the hole saws included but I have used a few of them. They cut fine thru tile but one of the hole saws was NOT manufactured correctly and had the shank slightly off center which meant the saw wabbled as you attempted to drill a hole with it. I mean, you get what you pay for, these are not high quality, top of the line hole saws, they are cheap chinese goods which met my needs. If you need something to last a long time, and be a professional level tool, then pay the price.

They work
was not expecting much for $16. but to my amazement one drill size went through two ceramic tiles and I used it again for the composite sink holes!. I did just what I read on the site- start at an angle and then rock the drill straight for a clean hole through your material.
