Abstract
A spinner roller set adapted for use in an apparatus used to connect and disconnect threaded drilling tubulars includes a first and a second modular spinner roller that mounts independent drive and spacer discs on a central shaft. The setup is arranged so that the spinner rollers when in use can engage a small diameter tubular using the same setup as that for engaging a much larger diameter tubular. When a drive disc is in need of replacement, the worn drive disc can be removed from the central shaft and replaced with a new drive disc. The other drive discs and spacers can be reused.
