Product Description
High quality bits with tiny diamond particles on the bit tip. This ensures a secure fit of the bit in the screw, reduces the contact pressure required and lowers the risk of slipping. Torsion zone – where kinetic energy is diverted from peak loads – and softer BiTorsion zone to prevent the bit tip from twisting under peak loads. This greatly extends the product service life. ¼” hexagon, suitable for holders as per DIN ISO 1173-D 6.3. BiTorsion bits included in the Wera “Take it easy” Tool Finder.

no good for impactors
Well I know people will be saying ( time machine) but paid £17.03 for this through amazon before Christmas so I don't think it's a good deal. But may be the cheapest at the moment. Have not used it to great extent yet so cannot comment on quality...

Me too. This price is around the going rate, give or take a quid or 2.

They are power bits.


Not impactor bits.. Just great for screwing stuff in.

Honestly you spend a day working standard bits that are expensive in an impactor and it can be gut wrenching.. Smashing another one every fifth screw

What would you recommend?

I don't have an impactor just a standard drill/driver Bosch thing. It's good enough for my needs but I'm getting fed up with cheap bits losing their threading (is that the term?). I think I need higher HSS rating or something. I'm clueless 😁
These are great but....id rather destroy the bit rather than the screw

Any impactor bits will be more hard wearing than standard bits ~ The Milwaukee ones are pretty cheap


Wera


Milwaukee


But if you are just using a normal rotary driver or manual driver ~ a lot is down to technique ~ Hold the tool in line and don't let it speed up so much that it starts spinning the bit in the end of the screw head ,and use the correct size bit.
Impactor guns are cheap now and are a tool in themselves if you haven't got one buy one ~ They come into their own with screw removal really or putting 3 , 4 inch or longer screws in
Impact bits aren't more hard wearing- in fact they're the opposite. They're more ductile (they'll deform more) than standard bits. Standard bits (from a decent brand) are much harder but that also makes them brittle, so they'll shatter under the impact loads from an impact driver. The higher ductility of an impact bit means it deforms rather than shatters, but does mean the bit is not as hard so is more likely to be damaged if it cams out etc.

Use the right tool for the job - these will be better in a hand screwdriver or a drill/driver, impact bits will be better if you're using an impact driver.
