You can get a plastic jug(milk etc.) fill with water, poke hole (size depending on flow you want) place near bit contact area. It flows automatically cooling and clearing debri from area. Thanks for the video
i usually have a magnet with me on cast iron jobs like this because washing the black cast iron residue down the sink has stained old old porcelain i have worked on before, and the magnet just attracts all the debris from the cast iron super good, i just wipe off the magnet and throw in the trash
Thanks for posting. I had to drill a hole in a cast iron shower base to install a shower door and was a bit unsure of how to go about it. Your video really helped! I appreciate it.
It wouldn't take nearly as long if you wasn't stopping so much. The consistency and intensity of the heat plays a major role in the process, intense heat makes steel, iron and any type of metal soft and volatile as long as the heat and friction of the drilling is constantly applied, the plastic milk bottle with water and drilled holes in it is actually a good idea for the water to constantly run on to the drilling surface preventing the constant stopping. Thanks for sharing though.
Just FYI, as I ruined my new Kohler sink today. Cast iron RUSTS very quickly. In the time it took to drill the sink, the first iron dust that was rinsed into the basin had rusted and stained the porcelain. The Porcelain all around the top and around the hole also now has a nice rust-colored hue to it. Does anyone have a suggestion for getting the rust stains out of a brand new $1,000 sink?
When I did this after watching your video i cut into the bottom of a togo soup container and placed it over the bit and stuck a stream into it from the sink to stop the splash, this created a hood which i kept down with duck tape and flowed the debris into the sink well. Does anyone have some ideas for how to keep the bottom clean?
I just need to put two holes in back splash of my sink in the garage to hold it to the wall. I plan on putting gaff tape so i don't chip the porcelain, cutting oil , slow speed, and a rare earth magnet to collect the cast iron so it doesn't go down the drain.
@@hectorworksout I added a step, starting with a 1/8 tile bit. Scored the mark, then drilled through the porcelain. Once through the porcelain, I used a normal drill bit to drill through the cast iron. I applied liberal amounts of water to carry debris away and keep the bit cool. Progress was slow, and uneven: at times the drill bit would not make much progress. At other times, it would be more effective. The drill bit speed was constant, on the "High" speed setting of two on my drill.
I've had several friends swear that the 5/8 Milwaukee diamond Max bits can go through this cast iron easily even though technically the packaging doesn't mention them.
