#23 Judy Tryniecki asks about ONSRUD 70-502 HSS Plastic drill bit Aug 28, 2020

I am attaching a grab bar to a 1933 era cast iron (I assume) on the top of the 'side' which is what is needed (tub and house have no resale value). It is the least expensive option (and doable). There is no solid wall along the other side (builder did shortcuts!). Thank you.
