M10 Basin Fixing Removal

[leevis]

Hi
In the process of swapping basins in my bathroom and found that the basin fixings on the old sink (M10 threaded fixings) were not in the right place so I got out mr Dremmel and removed them. The problem is that I couldn't cut them flush and they need some more work done on them before I drill the new ones in. Is there a better method to remove these? I have an oscillating multi tool but not sure if that would touch these bad boys. Dremmel just seems to eat discs.

Can you cut a groove in them with a hacksaw and undo them with a flat screwdriver. Or, if there's a good bit sticking out of the wall to get a grip on, you could try a stud extractor.

Or just grind them back with a grinder.

Funnily enough, I was watching this this morning. Not sure where you get the left handed drill bit though?

I never knew you could buy a left-handed drill bit. I wonder what they are used for (apart from removing sheared bolts of course).

Left handed holes, silly.
