Use and fit
Read the series on your machine and match the original barrel before ordering this spare. A dedicated polishing barrel makes sense if coarse grit is difficult to clear from your current one. Keep the fit limited to the series named by the supplier and confirm your individual revision before buying.

Questions before buying
Can I dedicate this barrel to final polish?
Yes, if your machine matches the supported Professional or Hobby series and revision. A separate clean drum helps keep coarse particles away from the finish.
