Wera BiTorsion Diamond Bit Pozi #2 50mm
Wonderful driving bit
I use this bit constantly with my impact driver, grips the screw heads well and does not cam out. Even when used putting screws into hardwoods this bit lasts and lasts well worth the money over the box sets of cheaper bits.

Disappointed with performance
After reading the other reviews rating this product highly, I opted to pay what is clearly a premium for the brand.
I was disappointed to find this piece slips just as much as other cheaper pieces I have used in the past.
It may last longer (although this is yet to be seen so rated 3* for reliability) but I won't be in a rush to pick this bit over any of the others in my box.
Next time I'll stick to the cheap bits...

The best bits you can buy
I've not come across bits that grip as well as these. They last really well too and so are good value.
This may be stating the obvious, but you must not use these with Phillips screws or you will see the damage shown in the pictures in another post.

Best Screwdriver bits around
These are the only bits I use, hard wearing and perform well.
