I would like a drill a hole through my dining room floor to run a wire. The floor is carpeted, so I pulled back the carpet in the corner to find an old linoleum floor. I attempted to drill a hole through it, but the linoleum seemed to melt and then form an impenetrable barrier. What type of drill bit could I use to get through the linoleum and the wood below?
Maybe a hole saw? I'd say it's worth a shot if you have one - or cheap ones are around $5-10. Otherwise, you could always try cutting with a utility knife until you're past the linoleum. Then drill after you've peeled it back. I doesn't have to be pretty if it's going to be beneath carpet.
Are you sure it's linoleum and not asbestos tile? Or maybe there is some old porcelain tile are running into? A hole saw should be able to cut though all of it, a high quality hole saw can cut most anything. If it is metal, a step bit should work too.
If it is asbestos do a little research first on the correct way to handle drilling holes. I won't assume to give any suggestions on the correct way to handle asbestos.
