For those of you out there that clear drains from time to time, I know you have been tempted and have succeeded in drilling a hole in cast iron pipe (regular and XH) instead of installing a cleanout. I regularly use an angle grinder with a diamond blade or metal cutting blade to cut cast iron. What type of drill bits do i need to be buying in order to drill through cast? I have tried titanium coated high speed steel, but all i seem to be doing is making them dull and putting shiny spots on the pipe. I have a ridgid 18volt hammerdrill to power these so i know it's not a lack of power. I assume i should have it on high speed to drill through cast. Any help is welcomed along with web page links to look at pretty drill bits.
