    Not precision enough
  

*by M***N on Reviewed in the United Kingdom on 19 February 2023*

Used to adapt router from 1/4" to 1/8" bits. First one I used introduced a run out of 0.3mm!!!! I could barely believe my eyes. This was so off centre. Compared with the collet that was standard on the router this is not acceptable.
