Fixing a broken screw gun driver

[olderdan]

I often break screw driver bits especially while using an impact gun

Hi ranald, It looks a though you could do with using a BiTorsion bit holder for your impact driver, the one I have is a WERA and has not broken a bit of any kind in years of use.

I have no idea what is inside these holders and do not intend to find out until it fails but they obviously have a shock absorbing ability without hindering performance.
