I usually buy Wera diamond-coated bits and make them last for as long as possible (months, rather than days or weeks).
However, I've just bought my first impact driver (yay! oodles of yummy torque!) and managed to completely trash the PZ2 bit supplied whilst just trying the damn thing out.
Now I can't afford to keep buying diamond-tipped bits if they're only going to last 5 minutes in the new beast, so I'm looking for your comments, please...
What brand do you use?
Do you go for standard quality or expensive (e.g. extra-hard/diamond coated)?
How long do bits last for you?
Considering that the likes of DeWalt sell them in packs of 25, does this mean that even the hallowed DeWalt brand is actually not very hard wearing, or do some people just go through them like wildfire (either because they do a lot of dry-lining/decking or because they're careless with their tool)?
