Broken centre drill recovery

[Robin Hewitt]

Not easy when your centre drill loses it's tip and you don't want to lose position :confused:

Bottom left hole in the piccy, looks a bit chewed but hey, it's there.

I attacked the remains of the drill tip with an ordinary masonary bit and smashed it to dust, then an undersized drill to make sure it was all out.

By now the hole was clear but way off centre. I switched the drill bit to a 5mm milling cutter and put it back on centre before drilling it through and threading it M6.

Amazed I got away with it
