Wera855/4 Z SB Tough Pozidriv Bit, PZ 1 x 89 mm, 05073523001
K**N
Not the hardiest of bits and will chew up with power tools and stubborn screws.
Does what it says, tightens or undoes screws. Good quality but you do pay more with wera but not very hardy and will get chewed up using with power tools.
N**.
Usual Wera Quality
Used several times and still in optimal condition.
