Now being serious, any worth in buying a hole saw...dyi and then charge $5 a person who might need the same help?

Most places I know of charge 30$ a hole but with them you get a much nicer hole with no blowout, the drill alone to do it properly is 600$ to buy unless you want to do it by hand

What I do is drill a hole in a piece of plywood just big enough to let the glass hole saw pass thru and sized so it can't wander then I clamp that board on the side of glass I can access and another on the other side without a hole (just for backing so no blowout) fill the hole in the plywood with water and drill away using nice even pressure and don't spin the drill to fast never any blowout and have been successful 100% of the time I do this with mirrors when we install them around taps in houses also no problems so far knock on wood
