Hmm, yes, first time I've seen those. Looks good. Wont have much purchase into the concrete wall though due to its thickness. Maybe fortify with pink stuff or something?

An adhesive will help. Really depends on the wall thickness.

Thanks. Another question, for drilling through concrete would I use the hammer drill option, or just the drill?

definitely the hammer. It will bash through.

It may help to make a bit of a dimple first, without the hammer, to keep the drill in the right spot.

With SDS driils bigger isn't always better. Most industrial rated 2kg and 3kg SDS drills are in the 550 to 850 watts simply because there is no need for them to be any more powerful (the real drilling power comes from the efficiency of the pneumatic hammer mechanism) and when the weight of an SDS goes much above 3 to 3.5kg they become difficult to control and very tiring to use for horizontal or vertical into ceiling drilling ( there are such things as concrete lintels and ceilings). Personally I wouldn't have one of those 1500 watt porkers if you were giving them away

Comments based on 30 odd years trade drilling with SDS drills

Can't compete with J&K's years of experience of course, but i have to agree. i have a 5kg SDS drill and it is my most Definitely last choice of tool to use. Frankly its exhausting to use, esp bearing in mind my 2kg one will probably be fine for the job in hand.

Be aware those prefab concrete garage panels are usually reinforced with steel bars, so drill gently and if you hit one move the drill bit away slightly and starts new hole. For what your doing you only need to drill in about 25mm using decent plugs.
Batten it then you could use fibreglass insulation and use sterling board to board it.
That's worked for me and still looks like new.

Have a few spare drill bits as the tip will be ragged off if you snag steel.

Those drills you linked to are demolition drills really.
I have several drills but I have not got one that big!
