Be prepared though, you can use up the screw bits quicker than with a
normal driver. They tend to break rather than wear out. Go and buy a tub
of 25 pz2 and pz3 bits while you're out shopping ;-) Oh - and make sure
they're the longer bits (50mm I think) rather than the more common 25mm
bits which don't fit the impact driver.

I tend to use the same Wiha diamond bits in the clickfix magnetic holder
with the impact driver, and they hold up reasonably well. As you say,
when they do go they tend to shatter or fall apart. The trick is to not
let them rattle about in the screw head too much, even though the impact
driver requires less pressure to drive the screw it is still worth using
enough to prolong the bit life.
