Are you constantly trying to deburr your rigid tube by hand? Stop hand cranking that cheap plastic reamer! The PrimoChill RFB (Rigid Finishing Bit) is a standard size drill bit with the power to save you time and energy while giving a perfectly finished tubing end. The RFB can be used at mid to low RPM to smooth out the end of your tube with no effort. Crank up the RPMs and you can customize the length of the tube as well. This functionality allows you to rough cut your rigid tube and then fine tune it to the perfect length with clean ends. Custom fitting your rigid tube is now so much easier!

  • Designed to Fit Standard Drills
  • Sealed Bearings That Allow for Scuff-Free Spinning
  • Material: PETG, PMMA (Due to extremely quick dulling of the bit, Copper tubing is not recommended.)

Parts Included
  • 1x Rigid Finishing Bit (Assembled)


Practice using the RFB on some scrap rigid or cut longer than needed until you get the hang of how fast or slow the bit will remove material.

Great Tool

Although this is for Rigid tubing, I used it for my PETG tubes and it worked great. It smooth the ends which I cut, where as the de-burring tool don't quite do the job. The price is well worth it.
