How do you drill through a steel lintel?
Pilot the hole first with a 3-4mm multipurpose drill bit.
Then swap to a titanium coated drill bit to cut through the steel.
To assist on a thick lintel try the following tricks:
1) Swap between a traditional drill bit and a bullet tip bit, this changes the cutting shape.
2) Use a cooling past on the drill bits to avoid overheating.
