Concrete – What bit should I use to drill a two inch hole in a solid concrete wall

concretedrillholemasonry

I am planning to install a 1.5-inch conduit through a poured concrete wall. I am planning on drilling a two-inch hole to accommodate the size of the conduit body. I have been searching up and down, but I don't know what drill bit to use. Bi-metal? Diamond? Carbide?

Hire a core driller. Trust me and do it. You will regret doing this yourself and the cost will seem like nothing in comparison to your struggles with drilling a hole that size in solid concrete.

probably cost you 200 bucks.

You can rent one from a tool rental company, or even from home depot.... https://www.homedepot.com/tool-truck-rental/Small-Core-Drill/3510639/index.html

But trust me, as someone who has do this five or six times a year, just hire someone for this job. By the time I calculate all the time and cost of renting a drill rig and diamond bit and figuring out how to use it and then returning it .... its never cheaper.
