My oven element has gone kaput, but I can’t get to it due to the screws being corroded and rounded.
My metal drill bits at low speed haven’t done much, but I think they may be crap.
What are the best type of bits for this job??
Left handed drill bits can be useful. I know it sounds like a joke, it’s not! But screws are tricky to drill, unless you’re happy to just take the head off, crosscutting the head often works better. Working on ovens is rubbish tbh
