I just bought another box of Dewakt PZ2 bits, cheap enough that it doesn't matter that they wear out or shatter
I was more concerned about the shrapnel flying off when mine shattered.
Safety squint needed


...enough to last for years!![]()
wira or wiha

I used up all the pz2 bits in the set & I switched to using one of the non impact rated wera ones & it lasted for ages before finally shattering. 
ThisI use Dewalt ones, the key to log life is the right bit to match the screw, and making sure your in straight and keep it pushed in.
