You can’t drill through a cast iron pipe with one drill bit. To get the desired size of the hole, you’ll need to use an array of drill bits. If you don’t have access to a drill press, you can use a hand drill to drill a hole in a piece of pipe. This is a great way to learn how to make your own hole saws.

Do plumbers still use cast iron pipes?
Iron pipes are usually found in older homes built during or before the 1970s. Builders preferred cast iron pipes for their ability to resist damage, as well as their ability to handle water. They are not usually installed in residential and commercial buildings. Iron pipes are made of iron, which has a higher melting point than steel.
This makes them stronger and more resistant to corrosion. They are also easier to install, since they don’t have to be welded together. Iron pipes can also be painted to match the color of the rest of your home or building.
Can threaded PVC go into cast iron?
Tying in to cast iron with PVC is a great way to add new waste lines. First, make your wye fitting. Using a regular wye, cut two lengths of polyvinylchloride that slip into the ends of the wye fitting and hold the no-hub fittings that attach to it. Once you have the two PVC pieces cut out, you will need to drill a hole in the center of one of them.
This hole will be used to attach the other PVC piece to the hub. Once the hole is drilled, use a small drill bit to tap the PVC into place. Make sure that you don’t drill too deep, or you’ll have to re-drill the same hole later to make sure it stays in place and doesn’t come loose. You’ll also want to use some hot glue to hold it all together.
If you’re using PVC, it’s a good idea to glue it to a piece of wood or something to keep it from sliding around. It’s also important to note that this is not a permanent fixture, so if you decide to remove it, be sure to take care of it before you do so.
