I tried to use these for an impact driver and they are too soft. Drove 6 screws then was toast.
THEY MIGHT have uses for a regular drill or screwdriver combo pack or something. I think not, but that is why I am not giving them 1 star. They don't cost a lot, so maybe someone else will fill us in later.
But for impact driver use.... no way. 5pc Power Bit Set #1 Phillips Chrome Vanadium Lifetime Warranty'
