Smaller pilot hole first, right bits and right drill combine to make more straight holes, otherwise the pressure you put on the drill to try and get through sends it all off at angles.
It's probably overkill for most jobs but my Titan 7kg SDS drill from Screwfix will get through anything and what I've used to get through the lintels above my windows when fitting curtain poles and blinds.

But I'll start with a smaller pilot drill bit.
) it went through the tough material that was resisting. Don't know if my old bits would have as I didn't use the hammer mode yesterday, but I'm sure these new ones have made lighter work of it. So now I'm getting somewhere! I'll need to put filler in those holes and paint over. I tested offering the pole up and surprisingly it looked like it sat pretty straight on this bracket.
I actually ended up drilling higher on the right side and ignoring my markings to compensate for the middle bracket but I wish I'd gone with my markings as now it seems higher on the right. But, meh, it's fine. After removing the bin liners that have been up for weeks, I used No Nonsense sealant remover to remove the sellotape residue that was on quite stubbornly. No Nonsense is absolutely amazing stuff, it completely cleans up. I'll fill the hole under the middle bracket tomorrow and I believe the paint is somewhere around.
