The inlaid handles of my cast iron manhole cover have rusted away. I need to drill holes in it to fit a small raised one. Can it be drilled and if so what drill should I use?
Any advice appreciated.
I’d plaster it with lime plaster, If you understood best building practice like me you’d know that.But Nige, I have the experience of lift manholes without drilling it. (and I'm guessing so do you!)

Don't forget to remove the cement based plinth first. It'll cause damp.I’d plaster it with lime plaster, If you understood best building practice like me you’d know that.
