How to cut through a porcelain tile floor
I have to cut part of a porcelain tile in my basement floor
They sell a special tool for this in your hardware stores. It is a hand held tile saw. It comes in a dry one or a wet one which keeps down the dust while cutting. You mark your spot, then set the depth you want and cut away.
AnAir chisel. Costs $20.00 at Lowes but you would need a compressor
