Ok there's no such thing as indestructible but what's the toughest brand

the market. Despite using pilot holes and the slowest speed on my Bosch
cordless, I've destroyed countless sets over the years. TIA.

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.

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.
