I need to affix some insulated plasterboard to the underside of an IG
Extra Heavy Duty steel lintel:

My plan was to glue and screw it in place, using Fischer UX plugs into the
aerated concrete blocks above. I therefore need to drill a few 6mm holes
through the lintel and was wondering how easy this will be?

The main reason I ask is that I've always found drilling metal hard work,
but then all my metal drill bits are those which either came with drills
or assorted bit sets. I'm sure in both cases they're the cheapest of the
cheap.

Ought something like this suffice?

Problem is that that situation, you'll blunt the drill with the first hole
you
drill when you go through the lintel into the aerated concrete blocks
above it. So you will need to sharpen the drill after each hole is drilled.

Better to glue the insulated plasterboard to the lintel with a decent glue.

Any other tips?
