Ive read plenty of discussions about the use, pros and cons of Cr-Mo for impact versus Cr-V. But what about extensions, U-joints and related stuff?
Granted, nobody wants a socket to blow up in their hand, which apparently can happen with the cheaper Cr-V stuff. But an extension should do just that - extend and minimize energy losses... So Id think you would want a hardder, more rigid item... Of course, the torque under impact, perhaps needs some give to be easier on the anvils or to prevent breakage... What do I know.
So, do you want extensions to be Cr-V or Cr-Mo? Ive seen that HF lower end impacts and all extensions are Cr-V, vs Cr-Mo. I tried seeing what snap-on used, to see the opposite end of the spectrum, but they don't seem to say.
So, whats best for impact?
