What kind of "destroyed"?

I find that most bits are fairly indestructible. It's the screw heads
that get mashed-up and rounded off after a couple of turns.

Which means either you are using a poorly fitting (or worn) bit, or
cheap and nasty screws.

With a good pozi bit to head fit, you should pretty much be able to lift
the weight of the driver itself, just holding the screw.


The worst screws were some which came with some Rawlplugs. I drilled
the correct size hole in the masonry and used the screws that came with
the Rawplugs (so there were definitely the right size) but they were
very difficult to screw in and kept sticking to the plugs, so I had to
use a fair amount of force. And before I'd got them fully in, the heads
of most of the screws were rounded-off. I ended up having to drill the
heads off, grab the shaft with a Mole grip and them and then use my own
screws which were a lot better. I think the ones I bought may have been
brass rather than steel.

For many thing that come with screws, the quality of screw often leaves
much to be desired IME.

I bought some long frame fixings and tore the heads off the screws with
the combi drill/driver.

I ended up having to grease the screws to stop them binding in the fixings
and snapping.
