Appreciate the responses - have always heard good things about DeWalt. Do many people here use Hilti? I know it costs a bomb but curious to know if the quality matches the price.
Milwaukee, Bosch, DeWalt, Makita and some others are pretty much the same, pick your favourite colour.
Hilti are a cut above but not sure its worth the difference in money unless you are going to be doing a lot of the same thing.
You will need.
A good battery SDS, something with enough clout but light enough to use one handed. No point having a 5Kg 56v monster for the occasional big hole then struggling with the vast majority of the holes you'll drill.
An impact driver is a must, don't go daft with power you're not taking wheel nuts off a bus.
A multi purpose drill for spade bits, step drills and hole cutters.
A multi tool, mine is 240 and I'm looking to get a battery one as there are many times i want to use it but can't be bothered with extensions.
A 4" grinder, I use mine a lot, mostly for trunking but will chop anything if it stays still long enough.
A lamp that fits your tool batteries, something hand held for inspection and lighting your work area, dont try to light the whole site.
As you progress...
An angle drill for joists makes running cables properly a joy rather than a chore.
A jigsaw.
A circular saw.
These are handy to have but i dont use them anywhere near as much as the first list.
