Here is a video from Project Farm for torx bits. Their PZ bit video doesn't have Wera I don't think but it might help with comparison. I use mainly Dewalt bits but only for heavy DIY and never had one break. I dont think Wera will be 4 times better but for trade use maybe it's more of the frustration of having to keep changing when they wear out!
You can buy a tub of 20/25 decent PZ2 bits for a fiver. Are Wera bits really worth 4 times as much? This for example https://www.amazon.co.uk/dp/B0160RIB52
Thanks. This would be more than a lifetime's supply for me then XD
Yes I have checked it for you and they are the same. I'm guessing the other pictures are other options
Okay, silly question. Is this a pack of 20 of the same bits?
