Recommend a impact gun (battery)

[Niall]

I must admit im yet to see a battery gun that particularly impresses me, and ive personally used a snap on one..Yes, for what they are there great...And i guess certainly serve a purpose / will un do most stuff.

But from my experience you cant beat a proper air one of decent brand (ingersol / snap on etc)..they just tear things apart (literally sometimes!) Do appreciate that not everyone has an air setup,so obviously depends.

I suppose for a portable tool, there good, but imo if you end up having to get the breaker bar out anyway, its not worth the money for me personally.

Agreed with that. The snap on ones are probably the best battery one I've used but still not as good as an air one.
IMO, go for mains unless your going to spend money on a decent battery one like a snap on. The cheaper battery ones are as much use as a chocolate fire guard.

Oh and ingersol Randd make Snap on air tools
