Wera Bi-Torsion Extra Hard Gold Pozi #3 25mm 5 5 4 4
Good product It's worth the extra money to use a hardened bit like this one unless you are screwing screws into something soft like balsa wood! I use Wera almost all the time. 23 Jan 2015
Very good Screwed about two hundred 6 x100 screws with two of these bits and one of the longer version. 6x100 - that's very heavy torque - very tough on bits. I was amazed at how long they lasted. The cheapo non branded bits lasted no time at all, and the Bosch Max Grip were not much better. 30 Nov 2014
Works anti-clockwise too!!! Wow - how do I convey the genius of these bits? I needed to use these bits to tighten some 150mm screws, which they did brilliantly. But I was amazed when I realised that I could use them to UNDO the same screws too!!! Amazing - they actually work both ways!! Utter genius - it's like having twice the number of screwdriver bits in your toolbox! To sum up if you need to tighten and remove woodscrews and don't want the expense of buying clockwise and anti-clockwise bits, buy these! They work both ways!! I'm still amazed...thank you Wera and Screwfix. 2 Aug 2013
hard as nails Chose this Wera as the cheapo bits I'd been using only lasted 10 minutes. Don't waste your money on inferior bits. This one lasts longer. That's all. 29 Nov 2012
