I’ve used 1/4” hex bits a fair amount, both in my own shop, and professionally. While I’m talking about the regular bits, not impact, there’s no doubt in my mind that the PB cannot be bettered.
I had one job that involved assembling a product with an air screwdriver, and we had to use a 2.5mm ball hex bit. We were getting about 20 assemblies out of each Wera bit before they broke, but when I switched to PB we didn’t break one.
In the U.K. and Europe, Wiha, Wera and Witte are “mid price” industrial tools. I favour the latter two, but I’m more than happy with either. PB are a notch up price wise, but also quality wise. Generally I’m happy to go PB Swiss, but sometimes other makers (usually Wera) are more suited.
If I was in the U.S. I’d probably be buying Zephyr as they are much better value that side of the pond.
I’ve used PB Swiss screwdrivers, ball hex drivers, hex keys and bits for nearly 30 years now. The first PB tools I ever got were ball hex drivers. They were used then, and still show no wear now. I don’t believe a comparable tool from any other manufacturer could match that performance. These drivers and bits from my service bag are newer, but still wearing well.
PB don’t make the best of everything, but they make the best of quite a lot!
