Advice re drilling 45mm dia hole JOB DONE!

I have just purchased a Status 530/5 TV antenna & mast.

Now I need to fit it.
I need advice on what to drill the hole with please.
Used to have a 'hole drill' but, in my opinion, it was a bit vicious to use on the motorhome roof.

Suggestions please.

TIA

Hi thats what I would use, make sure its sharp and the drill bit is as well, run it at a slow speed and it should be ok.

I used a 32mm one to fit mine and stew's Maxview dish.

IMO use a small dia drill bit to make 15 or 20 holes just inside the required dia and then use either a round or half round file to 'ease' the hole to the exact size . . a slower process but better [be exact - you only get one chance !

Sorry Olley, disagree (partially ) there.

Yes, make sure the drill bit and cutter are VERY sharp.
But...... NO, do not use slow speed when drilling a hole through THIN alluminium material.
Your roof will probably be 20swg (.036"/0.09mm) alluminium skin (or there abouts).
If you drill slowly through this material, odds on, as the teeth break through the other side, they will grab and rip the ally, ESPECIALLY if you apply too great a pressure.
Use a VERY fast speed and VERY light pressure and allow the cutter to take itself through the ally. This way you'll get a much neater finish and less chance of grabbing.
..........least, thats how we build aircraft

Hi Zaskar, I bow to your greater knowledge of drilling ali. Never found much of that on Dockside equipment.

If it's going on to a VW Clubman, surely they are drilling fibreglass ?

Thanks for all the advice so far.

Monocoque construction roof.

Did check Screwfix but they don't do a 45 mm one unfortunately.

Keep it coming

Hi tricia, if you use jonnyf's link they show a 44mm which would be close enough I am sure.
